Abstract
A method and apparatus for improving color matching between original color images and reproductions thereof. Incorporated into the improved color matching technique is an improved out-of-gamut mapping strategy which does not affect in-gamut colors but which ensures that colors outside of the input device gamut will be mapped to the boundary of the output device gamut while preserving hue and minimizing the combined chrominance-luminance error.
