The colors of industrial products such as cars, houses, and fabrics are determined by a color matching process. Color matching is a process in which colorants and their ratios should be determined. There are two methods for color matching, that is a visual color matching method and a CCM (computer color matching) method which is now used quite frequently. CCM can reduce the color difference. However, color correction must be repeated if there is poor color matching due to the limitations in color reproducibility. In color reproducibility invesigation, the same samples with the same colorant ratios must be maked several times. However, it is difficult to make several samples in the color matching process. We used reflectance simulation in CCM to obtain reproducibility in samples with different colorant ratios in color matching.
