説明

The color constancy for process color printing was maximized. A color inconstancy index (CII) was defined as the color difference between the CIELAB values under D50 and the corresponding colors under D50 that were transformed from tristimulus values under other illuminants, applying CIECAM02. Two methods were evaluated for Japan Color 2007. One was directly minimizing the CII. The other was controlling the amount of black ink where no CII information was given. It was found that the maximum black method was effective as a direct search method. When the illumination condition is unknown, the maximum black method might be the best way to maximize the color constancy for process color printing.
