Ripple patterns appear in my scanned image when using Epson Scan. What should I do?

• Try the following:
  • Select the Descreening check box. In Professional Mode, select an appropriate Screen Ruling for the Descreening and deselect the Unsharp Mask setting.
  • Select a lower Resolution setting. See Selecting the Scan Resolution.
  Note: You cannot remove ripple patterns when you are scanning using a resolution higher than 600 dpi.
