xii Introduction

The Glossary denes words in boldfor example, output prolethat appear throughout this manual. Color terms and concepts such as RGB data, color space, spot color, gamut, and source prole are used throughout this manual. If you are new to desktop color, or if any terms are unfamiliar, check the Glossary.

Key features of ColorWise ColorWise is the color management system (CMS) designed and built into the Fiery and designed to provide both casual and expert users with the best color output for a variety of purposes. The ColorWise default settings provide great out-of-box color from many Windows and Mac OS applications. This allows casual users to achieve good quality output without knowing about or changing any color settings on the Fiery.

For consistent color, calibrate the Fiery on a regular basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to calibrate using either the scanner that comes with the copier/printer or an optional spectrophotometer or densitometer (see Chapter 2).

ColorWise features let you modify printing results. Depending on your particular needs, you can:

Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset press standards.

Match PANTONE and other spot colors for the best match when printed using four-color press conditions or when printed using presses with extra, custom plates.

Select a color rendering dictionary (CRD), also called a rendering style, for RGB printing. CRDs allow for rich, saturated printing of presentation graphics; smooth, accurate printing of photographs; and relative or absolute colorimetric rendering for specialized needs.

Dene the source of incoming RGB color data for better screen matching and provide for better color conversion of RGB data with no source information.

Dene whether RGB data is converted into the full gamut of the copier/printer or whether it is rst converted into the gamut of another device, such as a press standard. This feature is very helpful for making one device behave like another. It is also useful for evaluating the appearance of the RGB le under different printing conditions without having to reprocess the RGB data each time.

xiii Key features of ColorWise

ColorWise color management (ColorWise) offers an open color architecture, letting users customize the Fiery to meet new printing needs as they arise. ColorWise supports ICC proles, which are industry standard color proles that describe the color behavior of a device. Downloading ICC proles to the Fiery enables the Fiery to simulate a custom press (or another copier/printer), as well as accurately print colors from a particular monitor or a scanner. In addition, you can create customized ICC proles for the copier/printer.

ColorWise also lets you use any Status T densitometer by importing data in a standard le format (see Appendix B). In this case, it is important to note that the quality of the instrument used will determine the quality of the calibration.

1-1 Managing color on the Fiery

The rst part of this chapter describes the options available from the ColorWise color management system and explains how to customize the color settings for your particular needs. It provides descriptions of the preset ColorWise default settings and covers additional options for users who need to customize ColorWise.

Beginning on page 1-14 is a detailed explanation of what a PostScript Level 2 or 3 printer driver does, as well as information on the capabilities of various printer drivers and instructions for setting color options with the PostScript drivers for Windows and Mac OS computers.

Managing color on the Fiery To modify the Fierys printing behavior, do any of the following:

Select ColorWise options for an individual print job using menus that appear in the printer driver.

Select most ColorWise options as server defaults from the Color Setup application in ColorWise Pro Tools (see page 3-37). Defaults can also be set from Fiery Setup or from the Control Panel, as described in the Conguration Guide. These defaults will apply to all subsequent print jobs unless you override them.

Select some ColorWise options, particularly default ICC prole settings and calibration options, from ColorWise Pro Tools. These options include default Simulation Prole (see page 1-9), Simulation Method (see page 1-10), Appear in Driver as (see page 3-8), default Source Prole (see page 1-7), RGB Separation (see page 1-8), and associated calibration set (see page 2-4).

Applications can generate color data for the Fiery in many different color spaces. The most common type of color data produced from ofce applications is RGB, while prepress applications generally produce CMYK data. Desktop applications can also generate spot colors, such as PANTONE colors. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colors. The Fiery lets users control the printing of these mixed-color documents with features that apply specically to RGB, CMYK, or spot color data.

Chapter 1: Fiery Color Management

1-2 Fiery Color Management

Fiery color management generates CMYK data to be sent to the copier/printer.

The following diagram illustrates the print options in the Fiery color management process that affect color data conversions. You access these print options when you send a print job to the Fiery. Most of these options and settings are described in subsequent sections of this chapter.

RGB Source Prole is the only color option that applies strictly to RGB color data. The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces.

NOTE: For users who are familiar with PostScript 3 color, RGB Source Prole affects all CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to the Fiery in CIEBasedDEFG format, for example, by choosing PostScript Color Management in Adobe Photoshop, the Fiery Rendering Style selectionwhich normally affects only RGB datawill also affect this CMYK data.

1-3 Managing color on the Fiery

Settings for the following options can be specied via print options when you send a job to the Fiery. Some can also be set as defaults by the administrator during Fiery Setup or using ColorWise Pro Tools. Settings specied via print options override the defaults.

Fiery color print option What it does

Color Mode CMYK/Grayscale or Print Mode Standard Color/Expert Color/Grayscale

Species the output color space of the job. Select CMYK, Standard Color, or Expert Color for a full-color document.

Combine Separations On/Off/1PgAutomatic

On/Off

Species whether to print separated CMYK data as a single, four-color composite document (see page 1-5). If you have the Fiery Graphic Arts Package option, you can combine an unlimited number of spot color separations along with the CMYK separations.

Rendering Style Photographic/Presentation/Relative Colorimetric/Absolute Colorimetric (Default set at Setup)

Applies a Fiery color rendering dictionary (CRD) to RGB data (see page 1-6), or to any incoming data with a PostScript source color space denition, including CMYK.

Brightness 85% Lightest to 115% Darkest

Performs a color adjustment on all color channels to make the printed output lighter or darker.

RGB Source Prole EFIRGB/sRGB (PC)/Apple Standard/Other/ Source 1-10/None (Default set at Setup or with ColorWise Pro Tools)

Applies an RGB source space denition to RGB data (see page 1-7). If you choose the Other setting, you can specify particular settings for Gamma, Phosphors, and White Point. See the corresponding options in this table. This option, along with Gamma, Phosphors, and White Point, only affects DeviceRGB or calibrated RGB color spaces.

(Other) Gamma 1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/2.6/2.8/3.0

Applies the specied gamma value to the RGB source space denition (see page 1-7). To use this print option, you must choose Other as the RGB Source setting.

(Other) Phosphors Hitachi EBU/Hitachi-Ikegami/NTSC/ Radius Pivot/SMPTE/Trinitron

Applies the specied phosphor (monitor type) information to the RGB source space denition (see page 1-7). To use this print option, you must choose Other as the RGB Source setting.

Applies the specied white point value to the RGB source color space denition (see page 1-7). To use this print option, you must choose Other as the RGB Source setting.

RGB Separation Output/Simulation

Determines which CMYK color space your original RGB data will be separated intoCMYK for the copier/printer (Output) or CMYK for a specied simulation (Simulation) (see page 1-8). It is important to note that when RGB Separation is set to Simulation, RGB colors are affected by CMYK Simulation Prole and CMYK Simulation Method.

CMYK Simulation Prole SWOP-Coated/DIC/Euroscale/ Simulation 1-10/Match Copy/None

(Default set at Setup or in ColorWise Pro Tools)

SWOP-Coated/DIC/Euroscale/ Simulation 1-10/None

(Default set at Setup or in ColorWise Pro Tools)

Adjusts CMYK color data to simulate an offset press standard or a custom color gamut dened at your site. The Match Copy setting bypasses Fiery calibration to match a copy made from the copier glass. Choosing None bypasses simulation (see page 1-9).

NOTE: Some of the Simulation settings have slightly different names depending on the model of copier/printer.

CMYK Simulation Method Quick/Full (Source GCR)/Full (Output GCR)/With CRD (Default set at Setup or in ColorWise Pro Tools)

Quick simulation applies one-dimensional transfer curves that adjust output density only. The Full simulations apply colorimetric transformations that adjust hue as well as output density (see page 1-10).

Paper Simulation No/Yes

Adjusts color output to compensate for the white point value of the paper stock used. This option is only available as part of the Fiery Graphic Arts Package feature set.

Output Prole Output 1-10 (Default set at Setup or in ColorWise Pro Tools)

The output prole is applied to all data in the print job (see page 1-10). User-dened output proles can be downloaded to the Fiery using ColorWise Pro Tools (see Chapter 3).

Detailed explanations of how these and other settings affect your print jobs are provided in subsequent sections of this chapter.

Combine Separations The Combine Separations setting species how to print separated CMYK data. If you have the Fiery Graphic Arts Package option, you can combine an unlimited number of spot color separations along with the CMYK separations. The Combine Separations options are:

Off prints each separation individually.

On combines separations as a single, composite-color document, and constrains the settings of the following print options: Color Mode (CMYK), Rendering Style (None), Pure Black Text/Graphics (Off ), Spot Color Matching (Off ).

1PgAutomatic combines separations as a single, composite-color document, overprinting plates in the order dened by the source application.

Black Overprint On/Off (Default set at Setup)

The On setting overprints black text placed on colored backgrounds; it automatically activates the Pure Black Text/Graphics option (see page 1-11).

Black Overprint Style Text/Text & Graphics

Species whether black overprinting should apply to text only or to both text and graphics. For this option to take effect, the Black Overprint option must be set to On (see page 1-11).

Spot Color Matching On/Off (Default set at Setup or with ColorWise Pro Tools)

The On setting enables Fiery-dened matching of spot colors to their best CMYK equivalents. If you have the Fiery Graphic Arts Package option installed, you can use Spot On to manage and edit these spot color matches (see page 3-22). Off instructs the Fiery to match color output to a CMYK combination specied by the source application for the document (see page 1-13).

Image Smoothing Automatic/Off/On/Below 90300 ppi

The On setting enhances the print quality of low-resolution images.

Rendering styles The Rendering Style option species a CRD for color conversions. You can modify the Rendering Style option to control the appearance of images, such as prints from ofce applications or RGB photographs from Adobe Photoshop. The Fiery allows you to select from the four rendering styles currently found in industry standard ICC proles.

Fiery rendering style Best used for Equivalent ICC rendering style

PhotographicTypically results in less saturated output than presentation rendering when printing out-of-gamut colors. It preserves tonal relationships in images.

Photographs, including scans and images from stock photography CDs.

Image, Contrast, and Perceptual

PresentationCreates saturated colors but does not match printed colors precisely to displayed colors. In-gamut colors such as esh tones are rendered well; similar to the Photographic rendering style.

Artwork and graphs in presentations. In many cases, it can be used for mixed pages that contain both presentation graphics and photographs.

Saturation, Graphics

Relative ColorimetricProvides white-point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to neutral gray. You may prefer this style to avoid visible borders when not printing full-bleed.

Advanced use when color matching is important but you prefer white colors in the document to print as paper white. It may also be used with PostScript color management to affect CMYK data for simulation purposes.

Relative Colorimetric

Absolute Colorimetric Provides no white point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to a bluish gray.

Situations when exact colors are needed and visible borders are not distracting. It may also be used with PostScript color management to affect CMYK data for simulation purposes.

Absolute Colorimetric

11-7 Managing color on the Fiery

RGB Source Prole The RGB source prole setting allows you to dene the characteristics of the RGB data in your document so that the appropriate color conversion can occur on the Fiery. Commonly used monitor color spaces are available from the driver and from the ColorWise Pro Tools Prole Manager. In addition, for special needs you can use ColorWise Pro Tools to download custom monitor or scanner proles.

When you specify a setting other than None for the RGB Source Prole, the Fiery overrides source color space denitions or proles that other color management systems may have specied. For example, if you specied a ColorSync System Prole on your Mac OS computer, the RGB Source Prole setting overrides it. In cases where you do not want this setting to override another specied source color space, choose the None setting.

When you specify a setting other than None for the RGB Source Prolesince the color space denitions are overriddenthe prints from the Fiery will be consistent across platforms. The Fiery RGB Source Prole options are:

EFIRGB species an EFI-dened color space recommended for users who have no detailed information about their RGB data.

sRGB (PC) species the industry standard denition for a generic Windows PC monitor.

Apple Standard species the denition of all standard Mac OS computer monitors.

Other allows you to specify custom RGB source settings. If you choose Other as the RGB Source setting, you can choose settings for the Gamma, Phosphors, and White Point options.

Sources 1-10 specify the denitions you download as RGB source proles. For more information about downloading RGB source proles, see page 3-4.

If you are printing with the PostScript driver from a Windows computer and have two-way communication enabled, the name of each downloaded prole is represented in the RGB Source Prole setting pop-up menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded proles appear as Source-1 through Source-10. For more information on two-way communication, see the User Software Installation Guide.

11-8 Fiery Color Management

None instructs the Fiery to allow the RGB sources you dened elsewhere, such as in the application, to be used. When you set RGB Source to None, the appearance of colors will not be independent of the le type. For example, RGB EPS les will look different from RGB TIFF les.

With RGB Source set to None, PostScript RGB data that contains a source color space denition is converted using the CRD specied by the Rendering Style option (see page 1-6). Non-PostScript RGB data and PostScript RGB data that does not contain a source color space denition are converted using a general undercolor removal (UCR) conversion method.

RGB Separation The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are converted to CMYK. The name of this option is meant to be descriptive, since the option denes the color spaces that will be used by the Fiery to separate the RGB data into CMYK values.

The two choices available for this option determine whether RGB data is converted into the full gamut of the copier/printer (output) or is rst converted into the gamut of another digital printer or press standard (Simulation). This feature is helpful for making one device behave like another for RGB data. For example, if a high-quality ICC prole is available for another print device, the copier/printer can simulate the behavior of that device.

RGB Separation is also useful for prepress applications. For example, it lets you experiment with the appearance of an RGB scan under different press printing conditions, without having to convert the RGB data to CMYK data for each condition. When the desired printing condition is found, you can then convert the le to CMYK, using the same CMYK simulation prole you used during the experimentation.

NOTE: The RGB Separation print option should be used in conjunction with the Output Prole or CMYK Simulation Prole print options.

Output converts all RGB colors into the CMYK color space of your copier/printer (when set to the printers default), or a customized CMYK color space for your copier/printer (when set to Output 1-10).

11-9 Managing color on the Fiery

Simulation converts all RGB colors into the CMYK color space for a specied simulation (make sure to select the desired simulation with the CMYK Simulation Prole print option).

CMYK Simulation Prole The CMYK Simulation Prole print option allows you to print press proofs or simulations. This setting species the offset press standard or other color printing device that you want to simulate. This option affects CMYK data only.

With the Windows 9x/Me or Windows NT printer driver, you can also view an unlimited number of custom Full simulations created using ColorWise Pro Tools. On Windows 2000/XP and Mac OS computers, you can view up to 10 Full custom simulations. The number of custom simulations is limited by the disk space on the Fiery.

If you are printing with the PostScript driver from a Windows computer and have two-way communication enabled, the name of each downloaded or custom prole is represented in the CMYK Simulation Prole setting pop-up menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom proles appear as Simulation-1 through Simulation-10. For more information on two-way communication, see the User Software Installation Guide.

The CMYK Simulation Prole setting you specify depends on the press standard for which the CMYK data was separated.

For images that were separated using a custom separation (such as a separation produced with an ICC prole), choose the corresponding prole on the Fiery with the CMYK Simulation Prole setting.

For images that were separated for SWOP, choose SWOP as the CMYK Simulation Prole setting.

NOTE: To properly simulate a printed image that was separated through the use of an ICC prole, the same prole must be present on the Fiery. For more information about downloading ICC proles to the Fiery, see Downloading proles on page 3-4.

11-10 Fiery Color Management

CMYK Simulation Method The CMYK Simulation Method setting species the quality of simulation to perform.

Quick applies one-dimensional transfer curves that adjust output density in the cyan, magenta, yellow, and black channels.

Full (Source GCR) provides a more complete and accurate simulation by applying colorimetric transformations that adjust the hue as well as output density of the cyan, magenta, and yellow channels. This option preserves the black amount determined by the simulation prole. Choose this option if you are printing a color proof to simulate output from a device represented by the simulation prole.

Full (Output GCR) applies the same simulation method as Full (Source GCR), but preserves the black amount determined by the output prole. Choose this option if you are printing nal output on the Fiery.

You should choose one of the Full options if you are printing an image separated using an optimized black generation (UCR/GCR) setting, either from a scan or from within an application such as Photoshop.

Output prole The output prole is applied to all data in the print job, so make sure the selected prole is the right one for your job. The default output prole consists of both a prole for your copier/printer, describing its color characteristics, and a calibration target that describes the expected behavior of the copier/printer.

In certain cases, you may want to customize the default output prole using the ColorWise Pro Tools Color Editor to achieve particular color effects (see page 3-10). If you do so, the new customized output prole is applied to all data in the print job. Changing the output prole only does not affect its associated calibration target (since the target is based on a copier/printer model). You can edit D-Max values of the calibration target separately (see page 3-6).

11-11 Managing color on the Fiery

You can use the ColorWise Pro Tools Prole Manager to download your own output prole to the Fiery (see page 3-4). Downloaded output proles are at rst associated with the calibration target that is tied to the default output prole. As mentioned above, you can edit calibration target D-Max values separately.

If you are printing with the PostScript driver from a Windows computer and have enabled two-way communication, the name of each downloaded or custom prole is represented in the Output Prole setting pop-up menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom proles appear as Output-1 through Output-10. For more information on two-way communication, see the User Software Installation Guide.

Pure Black Text/Graphics The Pure Black Text/Graphics option affects the printout for black text and vector graphics on a page. Under most circumstances, it is preferable to leave this option set to On. When Pure Black Text/Graphics is on, black colors generated by applications are printed using 100 percent black-only toner (for example, RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%). This means the black text and line art will not exhibit halftone artifacts and will not be misregistered, since there is only one toner used. In addition, this setting eliminates blasting. This option is automatically set to On when the Black Overprint option is set to On.

For some jobs, it is preferable to clear this option, for example, if the page includes gradient lls that use black. The following table describes the behavior of the Pure Black Text/Graphics option with black data dened in different color spaces.

11-12 Fiery Color Management

NOTE: The Pure Black Text/Graphics option can be used only when printing composites, not when printing separations.

NOTE: PostScript applications, such as QuarkXPress, may convert elements dened as RGB = 0, 0, 0 to four-color CMYK black before sending the job to the Fiery. These elements are not affected by the Pure Black Text/Graphics option. For details, see the application notes. Also, black text and line art dened as RGB = 0, 0, 0 in ofce applications (such as Microsoft Word) are converted to single-color black (CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows 2000/XP. To print this single-color black at the maximum toner density of the copier/printer, set the Pure Black Text/Graphics option to On.

Black Overprint The Black Overprint option lets you specify whether or not black textdened as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%overprints colored backgrounds.

OnBlack text overprints colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors. Setting Black Overprint to On automatically activates the Pure Black Text/Graphics option.

OffBlack text knocks out colored backgrounds.

Input black color

Pure Black Text/Graphics

RGB Prints 100% black With the default prole, prints a rich black using all toners.

CMYK Prints only with black toner, because CMYK simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the copier/printer.

Spot Prints only with black toner, because spot color simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the copier/printer.

11-13 Managing color on the Fiery

NOTE: PostScript applications may perform their own black overprint conversions before sending the print job to the Fiery.

One example of how you might use this setting is with a page that contains black text on a light blue background. The background blue color is CMYK = 40%, 30%, 0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%.

With Black Overprint On, the nal text portions of the page are overprinted, or combined with the underlying colors. This results in CMYK = 40%, 30%, 0%, 100% for the color used for the text. There is no transition in the cyan and magenta toners, and the quality of the output is improved since it will not show artifacts near the edges of the text. The option also works with text dened in the RGB color space, that is RGB = 0, 0, 0.

With Black Overprint Off, the border of the text is on an edge that has cyan and magenta toners on one side (outside the text) and black toner on the other side (inside the text). This transition may cause visible artifacts because of the practical limitations of the copier/printer.

Spot Color Matching The Spot Color Matching option provides automatic matching of spot colors with their best CMYK equivalents.

OnThe Fiery uses a built-in table to generate the closest CMYK matches of spot colors your copier/printer can produce. (New tables are generated when you add new output proles.) If you have the Graphics Art option installed, the Fiery uses the CMYK matches determined through Spot On (see page 3-22).

NOTE: Spot colors not included in the built-in table are treated as CMYK.

OffThe Fiery uses CMYK equivalents dened by the spot color manufacturer, such as PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.

For jobs that include spot colors, set Spot Color Matching to On unless you are printing press simulations. In that case, set Spot Color Matching to Off and choose the appropriate CMYK Simulation setting (see page 1-9).

NOTE: You can use the Spot Color Matching option only when printing composites, not when printing separations.

11-14 Fiery Color Management

Spot Color Matching and the PANTONE Coated Color Reference

The PANTONE Coated Color Reference (described in the Fiery Color Reference) prints differently depending on the Spot Color Matching setting.

OnThe Fiery uses a built-in table or, if you have the Fiery Graphic Arts Package option, the Spot On color dictionaries (see page 3-22) to generate the best matches of the PANTONE colors that your copier/printer can produce. The PANTONE number is printed below each swatch.

OffThe Fiery prints swatches using the CMYK values recommended by Pantone, Inc. (and used by applications that provide PANTONE color libraries). The CMYK values used to generate the color, as well as the PANTONE number of the color, are printed below each swatch. These CMYK values are printed through the selected CMYK Simulation and Output Prole settings.

PostScript printer driver for Windows and Mac OS You can access the printer driver options described in this section by choosing Start\Settings\Printers, right-clicking the appropriate PPD name, and choosing Properties (Windows 9x/Me), Document Defaults (Windows NT), or Printing Preferences (Windows 2000/XP) from the pop-up menu. To access the Mac OS driver options, choose Print from the File menu of your application. These settings are also accessible from the Print Setup or Page Setup dialog boxes of most applications.

For Windows computers, the Fiery driver interface enables you to save combinations of settings that you can later access. Additionally, you can choose different settings for individual jobs from the applications you use.

The printer driver writes a PostScript le containing the instructions generated by your application and the Fiery print options you chose. The printer driver sends the PostScript le to the Fiery. The Fiery then performs PostScript processing and color conversions and sends raster color data to the print device.

NOTE: The following illustrations and instructions do not apply to all applications. Many applications, such as Adobe PageMaker, Adobe Photoshop, Adobe Illustrator, QuarkXPress, and CorelDRAW, have other color management options in addition to those presented in the printer driver.

11-18 Fiery Color Management

The AdobePS driver includes the following Color Matching options.

Color/GrayscaleWhen this setting is used to print to the Fiery, ColorWise provides all color conversions on the Fiery. Typically, you should use this option when printing to the Fiery.

PostScript Color MatchingCan be used with PostScript devices such as the Fiery. It provides for color conversion using a color rendering dictionary (CRD) that is downloaded with the print job. This method requires that the le is saved as an EPS with PostScript Color Management selected.

NOTE: If you use the PostScript Color Matching option, the driver may, depending on the application in use, attach a CMYK source denition to the CMYK data in your document. In such a case, the CMYK data in the document is reseparated using a Fiery CRD. The destination color space for the CRD is determined by the RGB Separation print option. When RGB Separation is set to Simulation, CMYK data is printed according to all specied CMYK Simulation Prole and CMYK Simulation Method settings. When RGB Separation is set to Output, CMYK data is converted to the selected output proles CMYK color space.

ColorSync Color MatchingProvides for color conversion on the host computer. This option can be used with PostScript devices such as the Fiery, but it is intended for use with PostScript Level 1 devices. If you use this option, be sure to specify the Fiery ICC prole as the Printer Prole. ColorSync Color Matching is not a suggested color matching method because it does not work in conjunction with all applications and requires that you disable features of ColorWise on the Fiery.

22-1 An overview of calibration

Calibrating the Fiery ensures consistent, reliable color output. You can calibrate the Fiery using ColorWise Pro Tools in combination with any of the following color measurement instruments, available as separately purchased options:

X-Rite DTP41 automatic scanning spectrophotometer

X-Rite DTP32 automatic scanning densitometer

EFI Densitometer ED100 hand-held densitometer

EFI Spectrometer ES1000 hand-held spectrometer

By connecting the instrument to the serial port on your computer, you can quickly measure calibration color patches and download measurements to the Fiery. For information on setting up and operating the DTP41 and DTP32, see Appendix A.

You can also obtain measurements from the copiers built-in scanner and calibrate using AutoCal or ColorCal, which do not require the use of a measurement instrument and can be run from ColorWise Pro Tools or the Control Panel.

This chapter explains how calibration works and provides instructions for all calibration procedures.

For information on advanced calibration and simulation features available with ColorWise Pro Tools, such as editing proles and creating custom proles, see Chapter 3. A format for inputting color measurements from other densitometers is described in Appendix B.

NOTE: The procedures described in this chapter are fundamentally the same for Windows and Mac OS computers. The main differences are the interface cable and the port used to connect to the measurement instrument. This chapter shows screens and dialog boxes for the Windows version.

NOTE: The term computer is used to refer to any computer running ColorWise Pro Tools.

Chapter 2: Color Calibration

EX12

22-2 Color Calibration

An overview of calibration Calibration generates curves that adjust for the difference between the actual toner densities (measurements) and the response expected by the output prole.

Measurements represent the actual color behavior of the copier/printer.

Calibration sets are sets of measurements.

A calibration target that describes the expected behavior of the copier/printer is contained in each output prole.

Once you have calibrated the Fiery, a calibration set is stored. This calibration set will be used when it is associated with an output prole. Every output prole has an associated calibration set. If you have not specied one, the calibration set associated with the default output prole is used.

NOTE: Changing calibration has the potential to affect all jobs for all users, so you may want to limit the number of people authorized to perform calibration. You can set an Administrator password in Fiery Setup to control access to calibration (see the Conguration Guide).

Understanding calibration Although most users needs are met by the default calibration set, the Fiery allows you to choose a calibration set to customize calibration for specialized jobs.

Calibration allows you to:

Maximize the color reproduction capabilities of the Fiery.

Ensure consistent color quality over time.

Produce consistent output across Fiery servers that are connected to the same copier/printer.

Achieve better color matches when reproducing spot colors such as PANTONE colors or other named color systems.

Optimize the Fiery for using ColorWise rendering styles (CRDs) and CMYK simulations, and for using ICC proles.

22-3 Understanding calibration

How calibration works Success in obtaining satisfactory print quality from a color server such as a Fiery connected to a copier/printer depends on many factors. Among the most important are establishing and maintaining optimal toner densities. The density is the measure of the light absorbed by a surface. By carefully regulating toner densities, you can obtain consistent printed color.

Even with a calibrated system, toner density is affected by service settings, humidity, and temperature; density also tends to drift over time. Regular measurement detects day-to-day variations in densities, and calibration corrects for them.

Calibration works by creating calibration curves on the Fiery that compensate for the difference between actual (measured) and desired (target) density values. These calibration curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that will be made to the data you start with. Transfer functions are often graphed as input or output curves.

The Fiery generates calibration curves after comparing measured values to the nal target values for each of the four toner colors. The target values are based on the output prole specied.

Measurements

Measurement les contain numerical values that correspond to the toner density produced by the copier/printer when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.

To create a measurement le, rst print a page of color patches. Then measure the patches using either a color measurement instrument connected to a computer on the network or, if it is available, the print devices scanner. The new measurements are automatically downloaded to the Fiery.

22-4 Color Calibration

Output proles and calibration sets

Output proles and calibration sets dene desired calibration results. One or more output proles and one or more calibration sets are provided with the Fiery. When you calibrate the Fiery, you can select the calibration set that corresponds to the typical printing jobs at your site. This same calibration set can be associated with one or more output proles. (For more information on output proles, see page 1-10.)

Scheduling calibration In general, you should calibrate the Fiery at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the copier/printer is subject to wide uctuations in temperature or humidity, calibrate every few hours. For the best performance, calibrate whenever there is a noticeable change in print quality.

If you need to split a print job into two or more batches to be printed at different times, it is especially important to calibrate before printing each batch. You should also calibrate the Fiery after copier/printer maintenance. However, because the copier/printer may be less stable immediately after maintenance, wait until you have printed approximately 50 pages before you calibrate.

NOTE: Since printed output from the copier/printer is very sensitive to changes in temperature and humidity, the copier/printer should not be installed near a window or in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes, as well. It should be stored in a cool, dry, stable environment, and reams should remain sealed until they are needed.

Print color reference pages. You can print Color Charts from the Control Panel (see the Conguration Guide) or Command WorkStation (see the Job Management Guide), and the color reference pages included with the user software (see the User Software Installation Guide ). All of these pages include fully saturated color patches and pale tints of cyan, magenta, yellow, and black. Images with skin tones offer a very good basis for comparison. You can save and compare pages you printed at different times. If there is a noticeable change in appearance, calibrate the Fiery.

22-5 Using Calibrator

When you examine the Test Page, keep in mind that all color patches should be visible, even though they may be very faint in the ve percent and two percent range. Each colors patch set should show uniform gradation from patch to patch as the color lightens from 100 percent to zero percent.

If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated with time, show the pages to your copier/printer service technician to nd out whether adjusting the copier/printer can improve output.

Checking calibration status You can check whether the Fiery is calibrated, which calibration set and output prole were used, and when the copier/printer was last calibrated:

Print a Conguration page or Test Page from the Control Panel or Command WorkStation.

Select a calibration set in Calibratorthe last calibration and the user who performed it are displayed.

Using Calibrator ColorWise Pro Tools Calibrator lets you calibrate the Fiery using the measurement method of your choice.

Changing the calibration has the potential to affect all jobs for all users, so you may want to limit the number of people authorized to perform calibration. You can set an Administrator password to control access to calibration (see the Conguration Guide).

NOTE: Multiple users can be connected to one server with ColorWise Pro Tools, but only one user at a time can use Calibrator. An error message appears if you try to calibrate when another user is already using ColorWise Pro Tools to calibrate.

22-6 Color Calibration

Starting Calibrator You start Calibrator from the ColorWise Pro Tools main window.

TO CALIBRATE THE FIERY USING CALIBRATOR

22-16 Color Calibration

Using the EFI Spectrometer ES-1000 and EFI Densitometer ED-100 The EFI Spectrometer ES-1000 is a hand-held spectrophotometer that measures the spectral light reected from printed output and other colored materials. Since the ES- 1000 accurately measures both the density and color of printed output, it is an effective tool for calibrating the Fiery.

The EFI Densitometer ED-100 is a hand-held instrument that measures the density of printed ink and toner. Like the DTP32, the ED-100 is a reection densitometer that you can use to calibrate the Fiery.

The ES-1000 and the ED-100 are available as separately purchased options.

Setting up the ES-1000 To use the ES-1000 for calibration purposes, you must rst set it up for use with your computer. For best results, you should also calibrate the ES-1000 itself using the white point calibration card that is included with the instrument.

For complete instructions on setting up and calibrating the ES-1000, see the documentation that is included with the instrument.

The following illustration shows the different parts of the ES-1000.

All ICC proles in the selected directory on your computer are displayed in the list in the main Prole Manager window. However, because a prole is listed does not necessarily mean it can be downloaded to the Fiery.

33-6 ColorWise Pro Tools

Simulation proles should only be proles for those devices you want the Fiery to match in terms of color output characteristics. Output proles should only be proles for the device to which your Fiery is connected. Although CMYK printer proles can be downloaded as Simulation or Output, consider how they will be used. If you want the Fiery prints to look like another printer, download that prole as a Simulation. If you have a custom prole of the copier/printer your Fiery is connected to, download that prole as an Output prole.

4. Click the arrow to download the prole and click OK when the download is complete.

The new prole now appears in the list of proles on the right side of the Prole Manager main window.

For Mac OS computers, this prole must be associated with one of the predened names (Source-1 through Source-10 for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output) or set as the default before it can be used. For Windows computers, all proles can appear in the printer driver by their prole descriptions (see Dening proles on page 3-8).

NOTE: When an output prole is downloaded, it inherits the calibration target of the current default output prole.

Editing proles The proles on the Fiery can be customized to meet your specic needs and the characteristics of your copier/printer using Color Editor, either directly or through Prole Manager. For more information on editing proles, see Color Editor on page 3-10.

Managing proles Prole Manager lets you back up proles to ensure that no custom proles are lost when the Fiery software is updated. You can also upload a copy of a built-in Fiery prole to your workstation in order to use it with an ICC-aware application, such as Photoshop. Prole Manager also lets you delete unwanted proles.

NOTE: You can back up and delete only those proles that appear in the main Prole Manager window without a Lock icon next to them. Locked proles cannot be deleted, but most can be backed up.

4. To delete a prole currently set as the default or associated with a custom name, click Prole Settings and clear the default option.

33-8 ColorWise Pro Tools

Dening proles For Mac OS computers, before you can apply any downloaded or edited prole to a print job, that prole must be linked to one of the predened custom names, or you can set the prole as the default for all print jobs (see setting default proles, page 3-3). Ten names are available for custom prolesSource-1 through Source-10 for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output.

For Windows computers, all proles appear by their actual names in the printer driver. These xed names are used in the PPD so you can select proles for each job even if your driver does not have the capability to obtain an updated list from the server.

NOTE: A custom simulation prole is used to illustrate this procedure. The same steps apply for dening custom or downloaded output proles.

TO DEFINE A PROFILE

1. Start ColorWise Pro Tools and click Prole Manager.

For the purposes of this example, assume DIC-new is a custom simulation prole created with Color Editor and, as such, no information is displayed for DIC-new under the heading Appear in Driver as.

Custom prole created with Color Editor

33-9 Prole Manager

2. Select DIC-new in the Simulation list, and click Prole Settings or double-click DIC-new.

3. Select the Appear in Driver as option, choose one of the predened custom simulation names (Simulation-1 through Simulation-10) from the menu, and then click Apply.

NOTE: Choose a name that is not already linked with another simulation. If you try to dene two proles with the same name, you will get an error message.

For an output prole, the predened custom names would be Output-1 through Output-10.

NOTE: While you cannot delete a preset prole, you can use the name of a preset prole name for your edited prole when you select the Appear in Driver as option. This replaces the preset prole with your own prole.

When you choose Prole Settings for an output prole, the Use Calibration Set options also appear. You must calibrate the Fiery with this calibration set before this option has any effect. If you have never measured for this calibration set, default measurements will be used. For more information about calibration sets, see page 2-2.

In Prole Settings, you can also change prole descriptions for all non-locked proles.

33-10 ColorWise Pro Tools

4. Click OK.

Simulation-1 now appears under the Appear in Driver as column for DIC-new. Choosing Simulation-1 from the CMYK Simulation option of the printer driver applies the DIC-new simulation to the print job.

If you do not dene a custom simulation prole, your job will print with CMYK Simulation Prole set to None. If you do not dene a custom RGB Source or Output prole, the default prole is used.

33-11 Color Editor

Editing proles Color Editor allows you to create custom proles by editing existing simulation or output proles and saving the changes as a new prole. With Color Editor, you can ne-tune a prole on your Fiery to meet your exact specications.

NOTE: You cannot edit source proles; only simulation and output proles can be customized.

Color Editor has two Edit Modes for editing output proles.

CustomEdit output proles and save customized versions of them.

% DensityView the calibration target, which is one component of the output prole. You cannot make changes to the calibration target in this window, but you can import a new target (see page 2-2).

Color Editor also has several Edit Modes for editing simulations.

MasterCreate a custom master simulation that affects all print jobs to which it is applied, unless a linked simulation exists for the selected combination of simulation prole, simulation method, and output prole.

Quick, Full (Source GCR), or Full (Output GCR)Create custom linked simulations. Linked simulations affect the print job only if the corresponding simulation prole, simulation method, and output prole are selected. If you choose an output prole and simulation method for which you have created a custom linked simulation, that simulation is applied automatically to the job. If you choose a simulation method or output prole for which there is no custom linked simulation, the master simulation is automatically applied. For detailed information about simulation methods, see page 1-10.

NOTE: If you made edits to a master simulation after you created a linked simulation, the edits are not applied to the linked simulation.

If you use Dot Gain values, apply the settings rst, so that the curves are deected from their straight-line positions. Then make edits to the new curves. When you adjust Dot Gain values, all existing points on the curve are removed. A warning dialog box allows you to cancel Dot Gain settings before they are applied.

7. Use the plus and minus buttons to adjust brightness.

Changes to the brightness are reected in the curve(s).

8. To adjust the curves directly, click and drag points on the curve or enter numbers into the input and output boxes.

The graph maps the input percentage to the output percentage. (These percentages refer to the size of the CMYK halftone dots.) The curve you selected appears, and points along the curve are marked so you can adjust them.

NOTE: You should adjust points in this way only after you have entered the Dot Gain and Brightness values.

A curve with this shape makes a color appear lighter by reducing density in the midtones.

A curve with this shape makes a color appear darker by adding density in the midtones.

A curve with this shape increases contrast.

33-16 ColorWise Pro Tools

For greater precision, you can type percentages in the Input and Output boxes or use the arrow keys on the keyboard to adjust the curve. To use the arrow keys, you must rst click the curve to establish an anchor point that serves as a reference.

9. For an output prole, you can set maximum densities of the C, M, Y, and K channels.

You can enter the maximum densities, called D-Max values, of individual colors for proles that support density settings. D-Max settings are not available when editing Simulation proles in Master mode.

10. When you are nished, click Save and enter a name for the new prole.

The new custom prole is saved to the Fiery with the new name. If you edit one of the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), you may want to include the original name as part of the new target name (for example, DIC-new) to help you remember the source of the new target.

NOTE: Preset default proles are locked and must be saved with a new name.

For Mac OS computers, custom proles must be linked to one of the 10 predened custom prole names (Simulation-1 through Simulation-10 for Simulation or Output-1 through Output-10 for Output) in order to be accessible from the printer driver. You can create as many custom proles as you want, but a maximum of 10 are available from the printer driver at any one time. For information on linking custom proles to the predened custom prole names, see Dening proles on page 3-8. If you are using the printer driver for Windows, custom proles will appear in the driver window without being associated with a predened prole name.

If you set a custom prole as the default, you can access it from the printer driver without linking it to one of the predened custom names. Simply select Printers default from the printer driver.

NOTE: When editing a simulation prole in Quick mode, clicking Import at the bottom of the Color Editor window lets you import a custom Quick Simulation created on another Fiery using the previous version of ColorWise. The current version of ColorWise does not allow you to save custom Quick or Full Simulations independently; rather, they are saved as components of the same prole.

33-18 ColorWise Pro Tools

4. Edit and save the simulation as described in steps 5 through 10 of the procedure starting on page 3-14.

For this new simulation to be automatically applied to a print job, the CMYK Simulation, Simulation Method, and Output Prole settings must be the same as those used when you edited the prole. If the Simulation Method is different or a different output prole is selected, the Master simulation is applied.

NOTE: A Simulation Prole can have a custom Master and one or more custom links up to three links (Quick mode and the two Full modes) for each output prole on the system. (For the CMYK Simulation Prole option in the printer driver, note that if you select a custom prole for which the output ink percentage is greater than 0 and the input ink percentage is 0, the Use Master print option will have no effect.)

Undoing simulation edits You can undo the changes you made to simulations (master and linked) in the following ways:

If you have not yet saved your edits, click Done on the Color Editor menu bar, and do not save the changes.

If you saved your edits under a new simulation name and want to delete all edits (in Master, Quick, and Full modes) to the simulation, see page 3-7.

Correcting gray balance The AutoGray feature lets you use the copiers built-in scanner as a measurement device for correcting the gray balance of output proles. Gray balance refers to the quality of neutral gray tones in a prole. In many cases, gray tones may contain a bluish or reddish color cast. AutoGray helps shift these tones back toward neutral grays.

The current color appears in the center patch of the window.

2. To update the center patch to a neighboring color that more closely matches the target, click the corresponding neighbor patch.

Neighboring patches represent variations from the center patch and can be selected if they offer a closer match to the desired color. Clicking one of these patches updates the center patch to the new color and provides a new selection of neighboring colors. These patches are either lightness or saturation neighbors, depending on the option specied in the following step.

Center Patch

33-32 ColorWise Pro Tools

NOTE: When you select certain colors, an exclamation point icon may appear in the upper right corner of the window. This icon indicates that the center patch color lies at the edge of the copier/printers printable gamut and may not be reproducible. In such cases it is recommended that you use an approximate target that lies within the gamut, rather than the out-of-gamut color.

You can also click the center patch to enter CMYK values directly. For more information, see the procedure on page 3-34.

3. Use the following techniques to control how neighboring color patches are generated:

Select either Lightness or Saturation in the Color Directions Legend.

Lightness generates neighbor patches based on darker to lighter shades of the original color. This variation is displayed from left to right, with the original color remaining in the center of the middle group.

Saturation generates neighbor patches based on less saturated to more saturated variations of the original color. This variation is displayed from left to right, with the original color remaining in the center of the middle group.

Choose a setting from the Color Spacing menu to control the closeness of the neighbor patches.

A higher setting generates neighbor patches that differ more noticeably from the center color. As you get closer to your target color, you will want to reduce the color spacing to a smaller value.

Select Monitor Compensation to simulate how all the on-screen color patches will appear when printed on paper.

This simulation depends on the monitor prole that has been congured for the display. To specify the monitor prole, choose Preferences from the Edit menu in the Spot-On main menu.

4. Continue adjusting the color patch controls and clicking neighbor patches until the desired color appears in the center patch. Then click Print Pattern.

5. Choose Output Style, Paper Size, and Paper Tray options.

For Output Style, choose between Color Search Pattern and Color Neighbor Pattern. Color Search Pattern prints patches with the same pattern as displayed in the Color Search window. Color Neighbor Pattern prints patches in a three column by eight row format.

For Paper Size, choose the size of the paper you want to use for printing the patches.

For Paper Tray, specify the input tray for the paper you want to use.

6. Click OK to print the patches.

The Print Pattern test page prints with following information:

Center patch color CMYK value

Color spacing

Lightness or Saturation neighbors selected

Output prole selected

The goal of the Spot Color Search is to nd the color values that make a printed color patch match a target, not the screen simulation of it. Printing a Print Pattern of the neighbor color patches allows you to compare the printed patches to the color target. Once you compare the printed patches and nd the one that matches most closely, you can then select the corresponding patch on the screen.

7. When you have selected the desired target color in the Spot On Color Search window, click OK.

The edited color appears in the color list of the main Spot On window.

BB-1 Importing density measurements

This appendix describes Simple ASCII File Format, which can be used to import density measurements from measurement devices. To use your own measurement data from an alternate measurement instrument, record your individual readings in a text le and structure it as follows.

Simple ASCII Import File Format (SAIFF) This format describes Status T measurement data and is for import into the ColorWise Pro Tools Calibrator. The three possible le formats are:

1D Status T density for EFI 34 patch page

1D Status T density for EFI 21 patch page

1D Status T density for other pages (maximum of 256 patches per ink)

The le format is ASCII and has no tabs. A single space or multiple spaces are used as delimiters. Blank lines are not allowed. Each line in the le represents four patches (C, M, Y, K) of a specic ink value. Comments may be on any line in the le, and these lines start with a pound sign (#) followed by a space. A line with a pound sign followed by any character other than a space has been reserved. Comments must be on an entire line by themselves.

Each line of data contains ve values. The rst number is the sequential patch number (for EFI 34 and EFI 21 pages) or the ink value percentage (for other pages). The four values that follow are the density values of C, M, Y, and K of the corresponding patch. Lines are ordered either by increasing sequential patch numbers or by increasing the ink percentage.

For Windows computers, the le extension must be .cm1. For Mac OS computers, the le type must be TEXT.

Measurement data in EFI 34 and EFI 21 are paper-relative. For other pages, if the rst line corresponds to zero ink value, the Calibrator assumes that the measurement data is absolute and adjusts it to become paper-relative by subtracting the density values of the rst line from the remaining patches.
