What are the color adjustment steps for car repair paint
When repairing the paint surface of a car, it is very important to adjust the paint to be the same as the original car paint. And in the process of adjusting the color of car paint, we also need to adjust the brightness, chromaticity, and color using different spraying methods to achieve the best color. In terms of color matching procedures, color analysis, brightness adjustment, color adjustment, chromaticity adjustment, viewing, and proofreading are required. The detailed requirements are as follows:
1、 Color analysis. Color analysis is mainly conducted from three aspects: at the top, observe the paint from the front or a certain perspective to see if the color is too deep or too light; Secondly, check the color to see if the paint is redder, bluer, greener, or yellower than the original topcoat; Thirdly, check whether the color of the newly sprayed paint is higher or lower than the original topcoat.
2、 Brightness adjustment. The main factors that affect brightness include workshop environment, spraying method, solvent use, paint dosage, spray gun pressure, and the amount of pigment mixed correctly. It is necessary to comprehensively consider various factors when adjusting brightness to obtain appropriate paint brightness.
3、 Color adjustment. Only after adjusting the brightness can color adjustments be made. The colors of each color can only change in two directions: at the top, the colors will turn green or red. The colors include blue, purple, yellow, beige, and brown; Secondly, colors that turn yellow or blue include green, black, maroon, gray or silver, and white; Thirdly, the colors that turn yellow or red include bronze, red, and orange red; Fourthly, colors that turn blue or green include navy blue and turquoise. After selecting the correct color toner based on the materials provided by the car paint manufacturer, calculate the toner dosage according to the minimum limit. After sufficient stirring, spray a small piece of the test panel and compare the color with the original topcoat after drying.
4、 Adjust the chromaticity. After adjusting the brightness and color, start adjusting the chromaticity. If you want to make the colors brighter, it is necessary to readjust the first two items from scratch; If you want to make the topcoat gray, you need to spray a wet coating, and then spray a coating with a mixture of a small amount of white and a small amount of black at a lower air pressure at a distance.
5、 View and proofread. Finally, it can be viewed from three perspectives: first, perpendicular to the surface of the car; Secondly, from a point of view that just exceeds the reflection of the light source; Thirdly, observe the car's topcoat from a perspective of less than 45 degrees. Check if the color of the repaired and sprayed topcoat is consistent with other parts, and if not, proofread until satisfactory.
