Epson ES-1200C - Manual (Page 54)

The color on the display seems different from that of the original
image.
Check the settings of the scanner functions, especially data
format (bits/pixel/color), gamma correction, and color
correction. Try a different combination of these settings.
Check the capability of your computer, display adapter, and
software. Some computers can change the color palette to
adjust colors on your screen. (gee your computer manual.)
Exact matching of colors is very difficult. Check the manuals
for your software and your monitor for information on color
matching and calibration.
The printed color seems different from that of the originals.
Exact reproduction of colors is very difficult. See your software
manual or your printing company for guidance on color
matching.
The printed image is larger or smaller than the original size.
Check the image size settings in your software. Do not use the
size of the image on your monitor to judge the printed size.
