Abstract

A method and system for matching color displayed by source and destination display devices and particularly for providing color matching between a computer monitor and an ink printer. The technique of the present invention initially determines the combination and color value ratios of single destination color components that will cause the destination device to display a color that essentially matches each of fully saturated single and dual colors of a source display device. These combinations of single destination color components and their corresponding color value ratios determine the best available blends of destination device color components for printing source device colors. A color matching algorithm is employed to derive the color value ratios--one for each of the single destination color components. Each color component ratio is then scaled and linearly interpolated over a range defined by the color matching algorithm to generate a set of look-up tables (LUTs)--one for each single destination color component. Color matching is performed by 1) performing a first series of computational steps to translate the source color value into an intermediate color value which is expressed in terms of single destination color components, 2) accessing the set of LUTs with the intermediate color value obtained in step 1 to obtain a second color value composed of the scaled linearly interpolated color values stored in the LUTs, and 3) optionally performing a second series of computational steps to translate the second color value into a color value which is expressed in terms of the original source color components.
