Ripple patterns appear in my scanned image when using Epson Scan. What should I do?
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. Try the following if this occurs:
Original image Descreening applied
- Select the Descreening check box in Office Mode, Home Mode, or Professional Mode. In Professional Mode, select an appropriate Screen Ruling for the Descreening and deselect the Unsharp Mask setting. See Adjusting the Color and Other Image Settings for instructions.
Select a lower Resolution setting. See Selecting the Scan Resolution for instructions.
Note: You cannot remove ripple patterns when you are scanning film or monochrome images, or scanning using a resolution higher than 600 dpi.
