Colors Are Patchy or Distorted at the Edges of Your Image

Your Scanned Image Is Too Dark

An Image on the Back of Your Original Appears in Your Scanned Image
If your original is printed on thin paper, images on the back may be visible to the scanner and appear in your scanned image. Try scanning the original with a piece of black paper placed on the back of it. Also make sure the Document Type and Image Type settings are correct for your original. See Selecting Basic Settings for details.
Ripple Patterns Appear in Your Scanned Image
A ripple or cross-hatch pattern (called moiré) may appear in a scanned image of a printed document. It is caused by interference from the differing pitches in the scanner’s screen and the halftone screen in your original.

Scanned Colors Differ From the Original Colors
Change the Image Type setting in Epson Scan’s Home or Professional Mode. See Selecting Basic Settings for instructions. Select different combinations of this setting and the others mentioned below.
Change the Display Gamma setting to match your output device, such as a monitor or printer, in the Epson Scan Configuration window. See Epson Scan Help for details.
Adjust the Auto Exposure setting in Epson Scan’s Professional Mode. Also try selecting a different Tone Correction setting. See Adjusting the Color and Other Image Settings for instructions.
Try selecting the following settings in the Configuration window: Color Control, Continuous auto exposure, and Recommended Value (on the Color tab). Also try turning off the Fast Preview setting. See Epson Scan Help for details.
Check the color matching and color management capabilities of your computer, display adapter, and software. Some computers can change the palette of colors on your screen. See your software and hardware manuals for details.
Use the color management system for your computer: ICM for Windows or ColorSync for Mac OS X. With Windows, add a color profile that matches your monitor to improve on-screen color matching. (Exact color matching is very difficult. Check your software and monitor documentation for information on color matching and calibration.)
Printed colors can never exactly match the colors on your monitor because printers and monitors use different color systems: monitors use RGB (red, green, and blue) and printers typically use CMYK (cyan, magenta, yellow, and black).
