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.

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:
• If the Image Type setting is Color or Grayscale, adjust the Contrast setting.
• If the Image Type setting is Black & White or Grayscale, adjust the Color Enhance setting.
