Installing Your Software 1-3

Chapter 2 Calibrating Your System

Sometimes the colors of your original image do not match the colors you see on your screen and in the final printed output. This is because of the different color processes your scanner, monitor, and printer use to produce color.

The scanner and the monitor both create a range of colors by adding red, green, and blue (RGB) in different proportions and intensities (an additive color process). Printers, on the other hand, produce colors by combining cyan (C), magenta (M), yellow (Y), and black (K) inks (CMYK) to create the desired hues. This is a subtractive color process.

When you print a scanned image, the image goes through both the additive and subtractive interpretive processes to acquire colorthe first when it is scanned, and the second when it is printed on your color printer. As a result, the printed colors may not match the colors in the original.

Calibration allows you to fine-tune your scanner, monitor, and printer to produce colors that are very close to those in the originals. Use the procedures in this chapter to:

Calibrate your monitor to your scanner

Calibrate your printer to your scanner

Use the resulting calibration profiles when you scan an image.

Calibrating Your System 2-1

Calibrating Your Monitor to Your Scanner To calibrate your monitor to your scanner, you first need to perform a screen calibration using EPSON Scan! II and then enable screen calibration in TWAIN.

Performing Screen Calibration

Follow these steps to perform a screen calibration:

1. Select EPSON Scan! II in the EPSON Scan! II folder.

2. Choose Screen Calibration from the Calibrate menu. You see this screen:

3. Look at the display from a distance and adjust the slide bar until the separate rows have the same basic color intensity.

Tip: If the rows dont look the same after you adjust the slide bar, increase the number of colors your monitor displays, if possible, using the Monitor Control Panel; see your Macintosh documentation.

4. Choose OK.

2-2 Calibrating Your system

Note: If you use a different monitor or change your video resolution, calibrate your screen again.

Enabling Screen Calibration

Once you calibrate your screen, you need to make sure screen calibration is enabled (the default setting). Follow these steps:

1. Start EPSON Scan! II, if necessary.

2. From the File menu, choose Acquire to start EPSON TWAIN. You see the EPSON TWAIN screen.

If the screen is fairly small and has an Advanced button, it is the easy screen. Click Advanced to switch to the advanced screen. If the screen is large and has a Configuration button, it is the advanced screen.

3. Click Configuration to open the Configuration dialog box.

4. Make sure the EPSON Calibration radio button is turned on. If it isnt, select it to enable screen calibration.

5. Choose OK.

6. Close the EPSON TWAIN screen.

When screen calibration is enabled, TWAIN uses it as it scans images until you change this setting.

Calibrating Your printer to Your Scanner

If you are printing color images on a color printer, you must choose a calibration profile for each of the printers you use. Printer calibration profiles ensure that the colors in your printed images closely match those in the original.

Calibrating Your System 2-3

If you have one of these EPSON Stylus ink jet printers, Scan! II provides printer calibration profiles for you so you do not have to create them:

EPSON Stylus COLOR EPSON Stylus COLOR II EPSON Stylus COLOR IIs

EPSON Stylus Pro EPSON Stylus Pro XL

For these printers you simply select the printer calibration profile before you scan an image. See Scanning Using Calibration on page 2-8.

If you have a color printer that is not an EPSON Stylus, you must create a printer calibration profile using the instructions in this section.

To create a printer calibration profile, you must perform these operations:

Export a calibration chart from EPSON Scan! II to your application in a format your application can open and print

Scan the printed chart to create the printer calibration profile.

Exporting a Calibration Chart

Follow these steps:

1. Start EPSON Scan! II, if necessary.

2. Choose Export Calibration Chart from the Calibrate menu.

2-4 Calibrating Your System

You see the following screen:

3.

4.

5.

6.

7.

8.

9.

From the Export File Format pull-down menu, select a format your application software can open, such as PICT.

In the Export image as field, type the name you want to use for the calibration chart file, such as COLOR1.

Click Export to create the calibration chart in the EPSON Scan! II folder.

Exit EPSON Scan! II.

Start your image editing application.

Open the calibration chart file you just created in the EPSON Scan! II folder.

The calibration chart appears in the application window. It contains nine blocks of color gradations, some grayscale gradations, and a black border on three sides.

Save the calibration chart file. You can use the same name you assigned when you exported the chart, or you can assign a new name.

Calibrating Your System 2-5

10. Print the calibration chart on your color printer.

11. Exit your image editing application.

Note: To print images on more than one color printer, print the calibration chart on each printer youll use. If you plan to print the image on a service bureaus color printer, have them print the calibration chart on their printer so you can create a calibration profile for it.

Tip: when you label the printed charts to help you identify which printer produced them, dont write on the chart itself. Write on the back of the page.

Tip: If you plan to print your image on a printing press that requires a four-color separation, youll need to ask your service bureau or printer to create a color sample using your calibration chart. You can then use that color sample to create a calibration profile.

You are now ready to scan the printed calibration chart to create a printer calibration profile.

Creating Printer Calibration Profiles

Follow these steps to create a calibration profile for each color printer you want to use:

1. Start EPSON Scan! II, if necessary.

2. Place the printed calibration chart face down on the glass surface of your scanner and close the cover.

3. Choose Create Calibration Profile from the Calibrate menu.

2-6 Calibrating Your System

You see the following screen:

4. In the Filename field, type the filename of the calibration file you want to create, such as COLOR1 PRINTER.

Tip: If you are creating more than one calibration profile (for instance, if you have more than one color printer), make sure you assign a unique filename to each calibration profile so you can distinguish between them.

5. Click Continue. You see the EPSON TWAIN advanced screen. (If you see the easy screen, click Advanced.)

Calibrating Your System 2-7

6. If necessary, choose Color Photo from the Image Type pull-down menu.

7. Choose Calibration Profile from the Destination pull-down menu.

8. Click Scan. The program scans the calibration chart and creates a calibration profile. You see the EPSON Scan! II program screen.

Note: If a message appears indicating that the specified scan settings are incorrect, you need to reset the Destination options to their default settings. Click the Destination button to open the Destination dialog box; then select General for the Calibration setting, and 180 for both the Resolution settings. Save the settings by clicking Save; then choose Scan again. Always create calibration profiles using these default settings.

You can now use the calibration profile when you scan images, as described in the next section.

Scanning Using Calibration If you are using one of the pre-defined printer calibration profiles, such as one of the EPSON Stylus printer profiles, or you have created a custom calibration profile for your printer, you can now use that profile to scan your image.

Follow these steps to use a calibration profile when you scan:

1. Choose Acquire (or Place, or the appropriate command) from the File menu of your application or EPSON Scan! II.

2. If you see a submenu, choose TWAIN (and then EPSON TWAIN, if necessary). You see EPSON TWAIN advanced screen. (If you see the easy screen, click Advanced.)

2-8 Calibrating Your System

2. If you see a submenu, choose TWAIN (and then EPSON TWAIN, if necessary). You see EPSON TWAIN advanced screen. (If you see the easy screen, click Advanced.)

3. Click Destination to open the Destination dialog box.

4. If you have one of the EPSON Stylus printers listed on page 2-4, select the printer from the Destination Name pull-down menu. The Calibration description is assigned automatically. Go to step 6.

If you created a custom calibration profile for your printer, type a unique name for the profile, such as COLOR1 PROFILE, in the Destination Name field. Go to step 5.

5. From the Calibration pull-down menu, select the filename you assigned when you created the profile, such as COLOR1 PRINTER.

6. Click Save.

7. Click OK. You see the EPSON TWAIN advanced screen.

You can now preview or scan your image using the calibration profile for your color printer, as described in the next chapter.

Note: If your scanner does not support Text Enhancement Technology, the option does not appear or is grayed out in the Image Type dialog box.

Modifying the Destination

The Destination dialog box allows you to define different resolutions for each destination output device. You can also use it to modify, add, or delete a calibration profile for your output device.

To modify the Destination, click the Destination button. You see the following dialog box:

Selecting resolution settings Use the Resolution pull-down menus to select resolutions that produce the best results for your image type and output device. You can select one resolution for line drawings and halftones and a separate resolution for photographs.

The best resolution setting for your image depends on the type of image you are scanning and your final output device. The following table shows the best scanning resolutions for most needs.

3-10 Capturing Images From Within Applications

Optimum scanning resolutions Outputdevice Monochrome printer

Printing press or imagesetter

Grayscale 80-170

150-240

150-350

The higher the resolution you select, the larger the resulting image file. For example, an 8.5 x 11-inch photograph scanned at 300 dpi can produce a 24MB file. The same photograph scanned at 72 dpi creates a file of only 1.36MB. Large files take longer to process and print. Consider the limitations of your computer and hard disk drive when you select a resolution. To keep file sizes manageable, select the lowest possible resolution that gives acceptable quality.

Tip: As a rule of thumb for any image except line art, use scanning resolutions that are one third of your output resolution. For example, use a scanning resolution of up to 110 with a 300 dpi laser printer and up to 170 with a 600 dpi laser printer. For EPSON Stylus printers, choosefrom 100 to 240 dpi for 720 dpi output and from 100 to 150 dpi for 360 dpi output.

Tip: For printing on a commercial printing press, multiply the lines per inch (lpi) the press prints by 2 to determine the scanning resolution. For example, if the lpi is 150, scan at 300 dpi. (lf the resulting file is too large, try multiplying the lpi by 1.5 to determine the scanning resolutibn.)

Tip: If you plan to enlarge an image when you print it, scan it at a higher resolution than you normally would.

Adjusting the image size

Vertical and horizontal rulers along two sides of the preview window provide measurements for the image you have previewed. You can change the unit of measure for these rulers by selecting pixels, inches, or cm (centimeters) from the pull-down menu next to the Width and Height fields.

3-14 Capturing Images From Within Applications

The size of the full image or the selected area appears in the Width and Height fields. You can type new values in these fields to define a selection area of a specific size.

You can select the Lock icons to keep specific values in either the Width field or the Height field. Click the Lock icon once to lock the value in place; the icon shows a closed lock. Click it again to unlock the value.

As you modify your selection area or other image settings, you see the file size of the image in the Size field.

Note: Some applications convert the image to fu11 24-bit data, so the actual size of the image may be larger than the value displayed in Size.

The Scale field displays the amount by which an image is enlarged or reduced during a scan. You can use this setting to scan the image from half its normal size (50%) to twice its normal size (200%). To change this value, move the slide bar or type the value you want in the % field.

Note: If you increase the Scale, the Size value also increases to indicate a larger file size.

You can use the Lock icon to keep the scale value constant. Click the Lock icon once to lock in the value; the icon shows a closed lock. Click it again to unlock the value.

Saving and Exporting Images

You can always scan an image using your TWAIN-compliant image editing application. However, if your application is not TWAIN-compliant, you can use EPSON Scan! II to scan the image and export it in a format your application can open, as described in this chapter.

Saving a Scanned Image Before you export an image, you need to save it in its original EPSON Scan! II format. Otherwise, you will not be able to retrieve it again in EPSON Scan! II. Follow these steps:

1. Start EPSON Scan! II, if necessary.

2. Select Acquire from the File menu.

3. Select Scan to scan your image.

4. Choose Save AS from the File menu. You see the following dialog box:

Saving and Exporting Images 5-1

5. In the pull-down menu at the top, select the folder in which you want to save the file.

6. Type a filename for your image in the Save image as field.

7. Click Save.

The image is saved in the EPSON Scan! II file format. You can now open this file in EPSON Scan! II and export it with a different format, as described below.

Exporting an Image

EPSON Scan! II allows you to export an image in a file format your application software can use. For information on the file formats your software can open, see your software manual.

Note: Your application software cannot import images saved in the EPSON Scan! II file format and EPSON Scan! II cannot open an exported image file. Always save an image in EPSON Scan! II before exporting.

Chapter 6 Troubleshooting

If you have problems using the EPSON Scanning Utilities, or with the quality of your printed or scanned images, check the two sections in this chapter for possible solutions.

Problems Using the EPSON Scanning Utilities

When you select a TWAIN data source, EPSON Scanners is not listed.

Either the EPSON Scanning Utilities were not installed or they were not installed correctly. Reinstall the EPSON Scanning Utilities; see Chapter 1 for instructions.

Nothing happens when you select Acquire.

Make sure your scanner is turned on and the cables are connected properly.

EPSON TWAIN may not be selected as the TWAIN data source in your application. Youll usually find the Select TWAIN Source option under the File menu.

The EPSON TWAIN data source may not be installed correctly. Reinstall the EPSON Scanning Utilities from your installation diskettes; see Chapter 1 for instructions.

You may have selected the wrong SCSI ID for the scanner. Check the settings for your scanner and any other SCSI devices you may have. Then reinstall the EPSON Scanning Utilities.

Troubleshooting 6-1

An error condition may have caused your application or the TWAIN data source in the EPSON Scanning Utilities to stop working correctly. Save any documents in process and close any open applications. Restart your Macintosh to restore the TWAIN data source; then start your application and try again.

Sometimes an error condition may cause the computer to display a message telling you that your scanner is not recognized. If this happens, reset your scanner by turning it off and on or pushing the RESET button. Then restart your Macintosh and try again.

The system fails or an error message appears when you choose Acquire from your application software.

You may have more than one TWAIN screen open at once. Reset your Macintosh and use only one active TWAIN screen.

Your scanned image may be too big. Reset your system and reduce the size of the scanned image.

If you see an insufficient memory error message, you may not have enough memory allocated to the application to use it with EPSON TWAIN. Use the Finder Get Info window to increase the memory allocated to your application by 4MB to 5MB.

The EPSON Scanning Utilities do not start.

Make sure you are using a system with the minimum requirements for the EFSON Scanning Utilities. See the Introduction in this manual.

Check that the system requirements are correct for your software application and that your software supports your scanner model.

Be sure that you have correctly installed and set up your application software.

6-2 Troubleshooting

See if your Macintosh has enough application memory to run your software. If you are running other software at the same time, you may not have enough memory left. See the section on memory allocation in your Macintosh manual.

The scanner does not start scanning.

See that the scanners READY light is on.

Make sure the scanner's terminator and SCSI ID are set correctly.

After clicking the Preview icon, the image does not appear in the preview window.

Click on the TWAIN preview window.

The scan is not the full width you selected in the preview area.

The EPSON ES-300C and ES-600C scanners restrict the scan width to 4096 pixels at high resolutions. Choose a lower resolution for a wider scan.

After scanning and opening several scanned images, your application software fails and your scanned image is lost.

Save and close the scanned images before scanning a new one.

The size of your image increases after scanning it into your image editing application.

Your image editing software may be converting the image to full 24-bit data, which requires more disk space. See your application software manual for more information.

Troubleshooting 6-3

An error in the scanner or a paper jam in the Automatic Document Feeder caused an error message.

Remove the jammed paper or reset the scanner to clear the error condition; then try scanning again.

The Sharpness setting is grayed out in the Image Controls dialog box

Your scanner does not support the Sharpness feature.

The Document Source setting is grayed out in the EPSON TWAIN screen.

This is normal. You must first install an optional Automatic Document Feeder or a Transparency Unit to be able to select these as your Document Source.

You are using Adobe Photoshop 2.5.1 and the Color Drawing and Color Halftone options are grayed out in the Image Type pull-down menu.

This is because Photoshop 2.5.1 can scan only in 1, 8, or 24 bits per pixel, so you cannot use these M-bit per pixel Image Types.

The Preview icon is grayed out when the Automatic Document Feeder is selected under Document Source.

The preview feature is disabled when the Automatic Document Feeder is selected because the document would have to be fed through the feeder for the preview scan and then reinserted into the feeder for the final scan. If necessary, use the document table for previewing your document.

6-4 Troubleshooting

Auto Locate does not work when scanning two or more originals.

Make sure none of the documents are touching one another on the document table.

When you scan a monochrome image, the scanned image is reversed like a negative image.

If your application has an invert function, use it to reverse the image, or use the Invert option on the TWAIN advanced screen.

Some applications misinterpret the scanner data. Check with the applications manufacturer for an updated program version.

The default settings for Image Type and Destination dont meet your specific scanning requirements.

You can define your own settings; see Chapter 3.

The Halftone setting in the Image Type dialog box is grayed out.

Halftone and dither settings on most EPSON scanners are only available when the Pixel Depth setting is set to Black & White or 8 Colors (1 or 2 bits per pixel per color).

The application software displays an error message, freezes, or fails after scanning.

Make sure you close the TWAIN screen before switching to your application software.

The image you scanned may be oversized. Try reducing its file size by changing its resolution or dimension; then scan it again.

If you selected 16 Gray as the Pixel Depth setting, change to 256 Gray and try scanning again.

Troubleshooting 6-5

If you scanned an image at a high resolution (800 dpi) and at the maximum allowable width using the Color Photo Image Type setting, restart your Macintosh and reduce the resolution and the width of the scanned image. Then try scanning again.

If your application contains a scan manager feature, you may have closed it before closing the EPSON TWAIN screen. Scan your image again, but close the TWAIN screen before closing your applications scan manager.

If you selected 3-pass scanning in EPSON TWAIN, you may need to free some space on your hard disk to scan.

After scanning with an image editing application, the scanned image disappears.

Make sure you close the TWAIN screen before switching to your application software.

The rows in the screen calibration window do not match closely enough.

Try adjusting your monitors brightness and contrast settings.

The TWAIN screen changed its color settings after a preview scan.

Increase the number of colors or decrease the resolution your monitor displays using the Monitor Control Panel.

The colors in the Color Filter wheel do not reflect the gradated rainbow spectrum of colors.

Increase the number of colors or decrease the resolution your monitor displays using the Monitor Control Panel.

6-6 Troubleshooting

After starting a multipage scan using the Automatic Document Feeder, the image editing application freezes, displays an error message, or fails.

Reset the system and reduce the number of pages you are scanning with the Automatic Document Feeder.

After closing the EPSON TWAIN screen, a partial image of the screen appears over the scanned image.

Scroll the applications frame to clear the partial image.

After selecting a part of an image to scan, the image did not scan correctly.

Scan the whole image instead of a portion of it.

Problems With Image Quality This section tells you how to fix problems with image quality that may occur when you scan or print images.

The entire image is distorted or blurred.

Make sure that the document is placed flat against the document table.

You may have moved the document during scanning. Check the position of the document.

See that the scanner is not tilted or placed on an unstable surface.

Troubleshooting 6-7

Part of the image is distorted or blurred.

Part of the original may be wrinkled, warped, or not in contact with the document table. Be sure the document is uniformly flat.

Caution: Do not place heavy objects on the document table.

The edges of the document are not scanned.

The document table has non-readable areas around the edges. Adjust your documents position so that the image comes inside the readable area.

Color is patchy or distorted at the edges of the document.

If the original is very thick or warped at the edges, the edges of the image may be discolored. Cover the edges of the original with opaque paper to avoid having outside fight interfere.

If part of the original is outside the document table, the edge may not be in contact with the document table and may be discolored. Change the position of the original.

The image is faint or out of focus.

Make sure the document is placed flat on the document table.

Check your Gamma Correction setting.

Make the Brightness setting darker.

Make sure you have calibrated your monitor and printer to your scanner, and that you are using the resulting calibration profile. See Chapter 2 for more information

6-8 Troubleshooting

The image is too dark and without details.

Adjust the Brightness, Gamma Correction, and Shadow settings to lighter values and scan the image again. Also check the brightness and contrast values of your monitor.

Check that the Destination output device is set correctly. If it is set to Screen, output on a printer may be too dark.

Straight lines in the image are jagged.

The document may be placed at an angle on the document table. Align it so that the horizontal and vertical lines are carefully aligned with the rulers on the document table.

The image does not look the same as the original.

Make sure you have performed the calibration procedures and selected the correct printer profile; see Chapter 2.

Try different combinations of scanner settings.

Check that your software is correctly installed.

If you are importing an image file into your application software, see if the file format is acceptable for your software. Also check that the settings of your application and your image match. See your application software manual.

A line of dots is always missing on the scanned image.

If this happens only on your printed image, your printer or its print head may have a problem or need cleaning; see your printer manual.

If this happens on both your screen and printout, the scanners sensor may be malfunctioning. Consult your dealer.

Troubleshooting 6-9

Using halftoning, textured dot patterns appear in the image.

This is normal halftoning; see your scanner manual for examples.

The color on the video display seems different from that of the original image.

Depending on your monitor, its resolution/color settings, and your EPSON TWAIN settings, the screen colors may be different from the original. This may be normal, especially if colors in the printed image more closely match the original.

Make sure you have correctly performed the screen calibration process in EPSON Scan! II. Recalibrate and try again.

Check your scanner settings-such as Pixel Depth, Gamma Correction, and Color Adjustment-or try a different combination of settings.

The printed color seems different from that of the originals.

Check that you have correctly performed the printer calibration process in EPSON Scan! II using the correct printer calibration profile. Recalibrate and try again.

The colors in a printed image may not match the colors of the original image exactly because the scanning and printing processes use two different color interpreting technologies.

The printed image is larger or smaller than the original size.

Check the image size settings in your application and TWAIN. You may also have used the Zoom Preview icon. Do not use the size of the image on your monitor to judge the printed size.

6-10 Troubleshooting

The image cannot be printed on the printer, the printout is garbled, or the printout is not an image.

Check that the printer is properly connected to your Macintosh and is set up correctly; see your printer manual.

Check that your software is properly installed and set up for your printer; see your software manual.

Images cannot be scanned at all or only a few dots appear in the scanned image.

Try different EPSON TWAIN settings. Be aware that some settings disable others for a particular effect. Also, depending on your scanner, some features may not be available.

Set the Brightness, Highlight, or Gamma Correction options to darker settings and scan the image again.

If you selected Line Art as the Image Type setting and any setting other than Screen as your Destination setting, try increasing the Threshold setting to a higher value.

Moir (interference) patterns appear in the scanned image.

Moir patterns commonly occur when you scan images that include halftone screens. To minimize this effect, try any of the following solutions:

Move or angle the original slightly

Change the Sharpness setting

Change the Scale setting slightly

Select 3 pass for the Scanning Sequence.

Troubleshooting 6-11

When you select 16 Gray for the Pixel Depth setting, the scanned image appears black in your application software.

Choose 256 Gray for the Pixel Depth setting and try scanning again.

The image appears upside down and truncated in your application software after scanning.

Before you scan the image, reduce its file size to less than 1MB by adjusting settings on the TWAIN advanced screen.

When you select 256 Color for the Pixel Depth setting, the scanned image does not match the previewed image.

Select Color Photo as the Image Type and try scanning again.

Select 16 Million Colors for the Pixel Depth setting and try scanning again.

The image looks corrupted.

Check your printer driver settings. If the paper size is set larger than Letter or A4, select a smaller paper size or the maximum paper size your scanner can support. See your scanner documentation for more information.

You may need to choose a lower resolution for the video display setting using the Monitor Control Panel. See your Macintosh documentation for more information.

If you change Monitor settings, perform another screen calibration.
