Single silver powder computer color matching method and system used for car metallic paint

Abstract

The invention discloses a single silver powder computer color matching method and system used for car metallic paint. According to the method, color attributes of pigments are accurately described byutilizing a chromatics theory; optical data of basic colors of the metallic paint is established and stored in a database; when computer color matching prediction needs to be performed, color data ofa target car is read; the optical data of the related metallic paint in the database is called for performing accurate prediction calculation to obtain an accurate formula; and therefore, automatic color matching of multi-angle single silver powder car metallic paint is realized. The problems of long time, high cost and poor effect in car refinishing paint industry can be effectively solved; by introducing a multi-angle spectrophotometer capable of precisely measuring the color data, and proposing metallic paint mixed color matching for computer color matching of the metallic paint, automatichigh-precision color matching of the multi-angle single silver powder car metallic paint is realized; and the method and the system have the advantages of high timeliness, high flexibility and high precision.

Description

technical field [0001] The invention relates to the metal paint color matching technology in the automobile repair paint industry, in particular to a single silver powder computer color matching method and system for the automobile metal paint. Background technique [0002] Computer color matching can provide guidance for specific production practices and simplify the color matching process by using color theory to accurately describe the color properties of pigments. Computer color matching can be widely used in industries involving color such as paint, textiles, garments and automobiles. Computer color matching technology began in the 1930s. CIE (International Commission on Illumination) created the tristimulus value colorimetry system. Hardy successfully designed an automatic recording reflectance multi-angle spectrophotometer; The theory of absorption and scattering in the medium, which is the theoretical basis of most computer color matching systems in the present peri...
