Mixing ink is an important task in the color printing process. How well this work is done is directly related to the printing quality of the product. Because the color is bright and the brightness is good, the accurate hue is the basic requirement of color printing products. To achieve this requirement, the printing ink must be accurately prepared. Therefore, the operator should master good color knowledge and ink adjustment process. 1. It is necessary to master the changing rules of the three primary colors in order to achieve accurate ink preparation Any color can be mixed and mixed with different proportions of the three primary colors. The change of the hue of the ink makes use of this rule. such as: 1. The tri-primary color ink can be turned into black (approximately) after being mixed in equal amounts. 2. The three primary colors inks are mixed in equal amounts and white inks of different proportions are added to make light gray inks of various tones. 3. The three primary colors inks can be mixed in various proportions, and can be mixed into a variety of different shades of intermediate or multiple colors, but the hue is biased towards the primary colors with large proportions. 4. After the two primary colors are mixed in equal amounts, they can become standard intermediate colors; after the two primary colors are mixed and mixed in different proportions, they can be mixed into a variety of different colors, but the hue tends to be a large proportion of the primary colors. . 5. In any color ink, the hue appears brighter after adding white ink. After adding black ink, its hue becomes darker. The above-mentioned blending of primary colors into various colors is based on the subtractive color theory of the three primary colors. 2. When adjusting the ink, you should first analyze the hue of the color draft, and use the complementary color theory to correct the color shift and improve the setting effect. After receiving the printed manuscript, first of all, we should carefully appreciate and analyze the various colors in the manuscript, and weigh the proportions of the ink hue to be adjusted. Analyzing the color draft is to master a basic principle, that is, the three primary colors are the basic colors of any color. In general, applying the change rule of the three primary colors, in addition to the gold and silver colors, any complex colors can be prepared. However, in the process of process practice, it is not enough to rely on the three primary colors to prepare countless ink colors. Because, in fact, because the pigments used to make inks are not very standard, even the inks produced in each batch inevitably have a certain degree of difference in color. Therefore, in actual work, appropriate colors such as medium blue, dark blue, light blue, light blue, medium yellow, dark yellow, light yellow, gold red, orange red, deep red, light red, black, green, etc. should be added in appropriate amounts. To achieve the desired ink hue. There are many types of inks, but no matter how, in addition to the three primary colors of ink, other colors are used to supplement the deficiencies of the three primary colors. Any complex color always changes within the range of the three primary colors. As long as you master this principle, ink adjustment will not be a problem. After the color analysis determines the primary color and secondary color ink and this example, it can be adjusted. However, if there is a deviation in the hue prepared, the hue can be corrected using the complementary color theory. For example, if the hue of a certain hue is green, a small amount of red ink can be added to correct it. On the contrary, if the red taste is too heavy, blue ink can be added to correct it. Third, the inter-color and compound color deployment The so-called inter-color is made by mixing two primary colors of ink. For example, the color of the color is red and yellow, and the hue is orange; yellow and blue can get green; red and blue can become purple. The two primary colors are mixed and mixed in different proportions, and many kinds of intermediate colors can be prepared. which is 1. The primary colors pink and yellow are mixed in 1: 1 to get a big red phase; if they are mixed in 1: 3, they can get a deep yellow color; if they are mixed in 3: 1, they can get a golden red phase; 2. Mix equal amounts of primary colors yellow and blue to get green; if you mix with 3: 1, you can get emerald green color; if you mix with 4: 1, you get apple green; if you mix with 1: 3, you get dark green. 3. The primary colors pink and blue are mixed and mixed in a ratio of 1: 3 to obtain dark blue purple; if they are mixed in a ratio of 3: 1, an approximate green lotus color can be obtained. The compound color is derived from the blending of three primary inks. If they are mixed in different proportions, you can get many kinds of compound colors. 1. The primary colors pink, yellow and blue are mixed in equal amounts to obtain an approximate black; 2. Two parts of pink and one part of yellow and blue can be mixed to obtain brownish red; 3. Mix 4 parts of pink with 1 part each of yellow and blue to obtain reddish brown phase; if 1 part of pink and yellow, 2 parts of blue, can be blended with olive; 1 part of pink and yellow, 4 parts of blue Matching, you can get the green hue of single room. Fourth, the operation essentials of the deployment of black When blending inks, it is necessary to determine which kinds of inks should be used for blending according to the hue analyzed by the original. To adjust the lake blue ink, based on visual observation and practical experience, it can be determined that white ink and peacock blue should be mixed. Among them, white ink is the main color, and peacock blue is the auxiliary color. If you want to get deeper, add a little blue. To adjust the olive yellow-green ink color, it can be determined that the white ink is the main, plus light yellow and peacock blue and slightly pink. As long as the main color is determined, the other colors are auxiliary colors, which should be gradually added in small amounts and stirred evenly. After that, use two pieces of paper (the same as the printing paper), one of which is coated with a little adjusted ink, and use another piece of paper to scrape it to the thickness of the printed ink layer, which is suitable for comparison with the original. . When comparing samples, it is necessary to scrape the relatively thin and light parts of the ink layer on the paper surface to be more accurate. When adjusting the ink, you should also master a principle, that is, use inks of different colors as little as possible, that is, if you can use two kinds of ink, you should not use three kinds of ink to adjust, so as not to reduce the gloss of the ink. On the other hand, the scratched sample is a bit more muddy than the original color, so the printed color sample can be more accurate. After the ink tone of the sample is accurate, you can adjust the ink in batches according to their respective ink ratios to ensure the quality of ink adjustment and improve work efficiency. In summary, as long as we master the rules of the changes of the three primary colors, apply good color knowledge, practice carefully and analyze and summarize, we will be able to quickly and accurately distribute excellent colors with accurate phases, bright colors, bright colors and good printability. Ink lays a solid foundation for improving product quality.
