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
settings (if available) and try scanning again:
- Select the
Descreening setting on the Advanced Settings tab.
- Select a
lower Resolution setting.
- Place the original at a slightly different
angle.
