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 settings (if available) and try
scanning again:
• Change the Image Type setting and experiment with different combinations of the next settings.
• Adjust the Tone Correction setting.
• Adjust the Auto Exposure setting.
• Click Configuration , select the Preview tab, and turn on the Quality Preview setting.
