Color Matching/Correction
Color Matching allows you to fine-tune the colors of scanned
images so that they emulate the colors of your original source
documents as closely as possible. This is accomplished using
MagicMatch.
When you click on the MagicMatch checkbox (so a checkmark
appears) the Profile List displays. A profile is a list of applicable
calibration profiles, which MagicMatch uses to render a final output
image. If a printer or calibration profile is not chosen, MagicMatch
will calibrate the image to optimize its display on a monitor.
MagicMatch only functions when you are scanning in color mode.
When you are using Magic Match you need to disable the
Level/Curve and Color Adjustment/Balance settings in the
VistaScan Advanced window.
