Epson Perfection V500 Office Color Scanner

Selected FAQ

Ripple patterns appear in my scanned image. 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:
  • Select the Descreening checkbox in Epson Scan’s Home or Professional Mode window. 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 when you are scanning in Home Mode using a resolution higher than 600 dpi. In Professional Mode, you may be able to remove ripple patterns at resolutions higher than 600 dpi if you reduce the Scale setting.
