Design method of color sample of metallic glitter paint

Abstract

The invention relates to a method for designing a color template of metallic glitter paint, comprising the steps of: obtaining a color design drawing of metallic glitter paint; collecting Lab values ​​of basic colors; making a color template of plain paint; collecting the Lab value of the color template of plain paint, Calculate the color difference value of the Lab value of the color sample of plain paint; compare the color difference value of the Lab value of the color sample of plain paint with the color difference value interval, if it does not fall in the color difference value interval, return to production The color sample of plain paint; otherwise, make the color sample of metallic flash paint; collect the color of the color sample of metallic flash paint from multiple angles; solidify the Lab value of the color sample of metallic flash paint collected each time, and then install all Import the Lab value set of the metallic glitter paint color template; output the color paste ratio, effect pigment ratio, and metallic glitter paint color template Lab value set. The invention greatly reduces the dependence on human eye recognition, greatly improves the accuracy of recognition and comparison, and makes the final design result more accurate and the error smaller.

Description

technical field [0001] The invention relates to the technical field of metallic glitter paint design, in particular to a design method of a metallic glitter paint color template. Background technique [0002] Metallic glitter paint is based on ordinary plain paint, adding effect pigments, so that the final paint surface has various flashing effects in addition to the color of plain paint; metallic glitter paint is especially used in the field of commercial vehicles. widely. [0003] For the design of metallic glitter paint, the existing technology is generally manual color matching. The specific steps are: the designer designs the ideal metallic glitter paint color on the computer; the color grading staff adjusts a large number of different metallic glitter colors according to the effect displayed by the computer. Paint samples; spray different metallic flash paint samples into color samples; manually pick out the color samples closest to the designer's ideal metallic flash...

AI Technical Summary

Problems solved by technology

[0005] 1. Because the colors designed by the designer on the computer will have different visual effects due to screen, printing or other technical reasons, so that the colors presented in different technical ways are very different in the eyes of colorists, so that the production The metallic glitter paint samples that come out are also very different;

[0006] 2. Since the color matching and selection of samples are completely dependent on the visual ability and experience judgment of the color palette personnel, the produced metallic glitter paint samples are quite different from the ideal color designed by the designer;

[0007] 3. Due to the existence of effect pigments, the visual perception of the color swatches of metallic glitter paint from different angles is very different for human eyes, which leads to the step of manually selecting the color swatches that are closest to the designer’s ideal metallic glitter paint color. In the process, subjective uncontrollable factors are magnified, and the obtained color sample is not the closest to the designer's ideal
