The basis of color matching
First of all, we should make a preliminary judgment of the ink color to be used according to the original hue, and then take the right amount of colored ink, on the ink platform for a small amount of deployment. Deployment, according to the color material subtractive complementary color principle, complementary color addition and subtraction. In the deployment of color ink, to treat the complementary color correctly, sometimes to avoid, sometimes to use. If in the deployment of intermediate color or dilute the original color ink, should try to avoid the mixing of complementary color ink. Because the more complementary color is mixed, the more achromatic components are added, the chroma of the color decreases and the color darkens. When the ink is adjusted to the same color as the original manuscript, the printing paper can be used to scrape the ink sample and compare it with the original manuscript. The specific methods are as follows: put the standard ink in the upper left corner of the identification paper, and put the matching ink in the upper right corner. Use a scraper to vigorously smooth the thin compress part at an Angle almost perpendicular to the scraping paper and quickly expand the thick compress part at an inclined Angle with light force. After the ink surface is dry, the ink hue can be observed in the thin compress part, and the black belt part can be identified as the hiding power and transparency of the ink; In the thick part to judge the difference between the two gloss and observe the appearance of the whole color, usually black and color ink using white scratch paper, and white ink using black scratch paper.
If there is color deviation, add color correction until it conforms to the printed sample. Ink hue adjustment can calculate their respective components, in order to proportionally to the deployment of batch. If the use of three primary ink deployment of dark ink, should master their change rules, in order to improve the effect of ink. Such as: three primary color ink equal mixing, the color obtained is approximately black; Three primary color ink in the two primary color equal or unequal temperature adjustment, can obtain a variety of intermediate color. Its hue tends to the color fruit with large content ratio; Multiple colors can be obtained by mixing the three primary colors with different proportions. Any color ink added to the black ink, its brightness must decline so that the hue becomes dark. If white ink is added, its brightness will be improved. Intercolor and compound color can be mixed with three primary colors of ink, but from the deployment of convenience, as far as possible to reduce the number of ink types, can use intercolor primary ink deployment.
