Document Type and Number:
Japanese Patent JP3406675
Kind Code:
B2
Abstract:
PURPOSE: To provide a paint color matching method that can rapidly obtain precise mixture.
CONSTITUTION: In this paint color matching method, the predictive result obtained by computing the paint film color of a mixed paint, obtained by mixing plural raw material paints, on the basis of basic data every raw material paint is compared to the colorimetric result of a color sample, and raw material paint mixture with the difference between both results being within a specified range is obtained. At this time, the predictive result is computed by a two- constant method, and when the difference between the colorimetric result and predictive result is not within the specified range, a single constant method is applied, or in a color matching method to a color sample with high saturation, the predictive result is computed by a single constant method.
