UNDER COLOR ELIMINATION PARAMETER TABLE, GRAY COLOR ELIMINATION PARAMETER TABLE AND GENERATING METHOD FOR COLOR CONVERSION TABLE

摘要

PROBLEM TO BE SOLVED: To generate a UCR parameter table representing a value K with respect to a combination of CMY suitable for a given print condition. SOLUTION: A printed matter in CMYK(cyan, magenta, yellow, black) and their mixed color are generated, a color measurement device measures a color of the printed matter, the result of color measurement and the Neu gebauer equation are used, a ratio of CMY providing the same chromaticity as white paper is calculated, the ratio of the calculated CMY is used to generate a density reproduction characteristic graph and the generated density reproduction characteristic graph is referenced to generate a UCR parameter table representing the K with respect to the combination of the CMY in the case of conducting predetermined UCR(under color reduction).
