Matching hardcopy color to display color.

摘要

A method for matching hardcopy color to display color for registered-dot ink-jet copies. Video RGB is converted into chromaticity coordinates in XYZ color space. An explicit solution is achieved by defining a new MSW color space which restricts the hardcopy colors to some percentage of one of the binary Mixtures of inks, some percentage of one of the Single inks, and some percentage of paper White. The color data in XYZ space is converted to MSW space and unreachable colors are mapped into reachable colors. Correction for hardcopy non linearities is accomplished by considering the interaction among the inks by using a coverage ratio to correct for color shifts. The MSW values are, thus, converted to CMY values which are sent to an appropriate dithering algorithm for conversion into dots on the paper.
