The tinting work of car topcoat repair paint is very complicated, and the main methods currently used are manual tinting and computer-aided tinting. Generally speaking, automotive repair coatings are made up of three parts: the masterbatch part, the resin part, the solvent, and the auxiliary part. The color masterbatch is composed of the leading color paste with high pigment content. There are metallic paint series color masterbatches and monochromatic paint series color masterbatches. Resin is the main component of coating film formation, and the color masterbatch also contains part of the resin, which is one or more of the resin parts. Solvents are mainly used to adjust the viscosity of the finished paint. The color masterbatch and resin part also contain some solvents. All solvents in the paint must be designed according to the curing method and operation method of the paint.
Manual toning is that the operator judges the hue of the reference color panel based on the visual inspection of the reference color panel, determines its color composition, repeatedly adjusts the contrast to determine that there is no difference in hue, then determines the difference between saturation and light and dark, and repeatedly adjusts the contrast to adjust the light and dark. And saturation, and finally make the blended paint color and the reference color plate have no visual color difference.
Computer toning is to use the computer to digitize the hue and brightness of the reference color palette, and to compare and calculate it with the various color masterbatch standard colors that have been stored in the computer to determine the definite composition of the reference color palette. The color operator uses the computer toning formula to make the paint, and then uses the color difference meter to determine the color difference, and the computer or manual fine-tuning of the color adjustment process.
