Scanned Image Colors Do Not Match Original Colors
Printed colors can never exactly match the colors on your computer monitor because printers and
monitors use different color systems: monitors use RGB (red, green, and blue) and printers typically use
CMYK (cyan, magenta, yellow, and black).
Check the color matching and color management capabilities of your computer, display adapter, and the
software you are using to see if they are affecting the palette of colors you see on your screen.
To adjust the colors in your scanned image, adjust these Epson Scan 2 settings (if available) and try
scanning again:
• Make sure you select the correct
Image Type
for your original.
• If the
Image Type
setting is
Auto
,
Color
or
Grayscale
, adjust the
Contrast
setting.
• If the
Image Type
setting is
Black & White
or
Grayscale
, adjust the
Color Enhance
setting.

Image Colors are Patchy at the Edges
If you are scanning a thick or warped original, cover its edges with paper to block external light as you
scan it.

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 on the Advanced Settings tab.
• Select a lower
Resolution
setting.
