ABSTRACT:
A color processing system is provided that specifies color in a standardized, perceptually uniform color space and resolves color differences between input and/or output devices. The color processing system utilizes a color mapping techniques to adjust the results of color mapping to fit the color gamut of the output device. The color processing system may be implemented as a color rendering dictionary in a PostScript.RTM. Level 2 interpreter. An additional feature involves adaptation of PostScript.RTM. Level 1 applications to take advantage of the improved color processing system and PostScript.RTM. Level 2 flexibility.
