A ripple pattern (called moiré) is a pattern that 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.

• Select the Descreening Filter check box in Epson Scan’s Home or Professional Mode window. In Professional Mode, set the Screen Ruling of the Descreening Filter setting to an appropriate setting for your document and deselect the Unsharp Mask Filter setting.

• 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 Macintosh. 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).
