Ripple Patterns Appear in an Image
You may see a ripple pattern (called a moiré) in scanned images of printed documents. This is caused
by interference from differing pitches in the scanner's screen and your original's halftone screen. To
reduce this effect, adjust these Epson Scan 2 settings (if available) and try scanning again:
• Select the
Descreening
setting.
• Select a lower
Resolution
setting.
• Place the original at a slightly different angle.
