Making ink is an important work in the silk printing process. How this work is done is directly related to the quality of printing. Because bright color, bright brightness, accurate color phase are the basic requirements of silk printing, to achieve this requirement must first accurately deploy the printing ink. Therefore, the operator should master color knowledge and ink adjustment technology.
1.Master the three primary color change rules
To achieve accurate ink deployment. Any color can be mixed with different proportions of the three primary colors (magenta, yellow, green), the color phase of the ink changes, it is the use of this law. For example, three primary color ink can become black (approximate). Three original color ink equal amount of mixing and add different proportions of white ink can be matched into a variety of different colors of light gray ink. If the three primary color ink is mixed according to various proportions, it can be deployed into a variety of different colors or compound colors, but its color phase is biased to the larger proportion of the primary color phase. If the two primary color ink mixed, can become the standard intercolor; the two primary color ink mixed to different proportions, can be matched into a variety of different colors, but its color tends to be a large proportion of primary color. In addition, in any color ink, the color is brighter when white ink is added. On the contrary, adding black ink becomes dark and dark. The above deployment of primary color ink into various colors is according to the theory of three primary color reduction methods.
2.Analysis the color phase of the original manuscript.
Use the color repair theory to correct the color bias and improve the ink adjustment effect. When you get the color sample, first of all, the various colors in the original draft should be carefully appreciated and analyzed, and think about the proportion of the ink color phase to be deployed. Analysis of color sample is to master a basic principle, that is, three primary colors is the basic color of any ink color. Apply the change law of three primary colors, except for gold and silver colors, any complex color can be deployed. However, in the process of process practice, only by the three primary colors to deploy countless ink colors, is not enough. Because the paint for making ink is not standard, and even each batch of ink produced inevitably has a certain degree of color difference. Therefore, in the actual work, it should also use such as medium blue, dark blue, light blue, light blue, blue, medium yellow, dark yellow, light yellow, gold, orange, deep red, light red, black, green, and other ink to add, to achieve the desired ink phase. There are many types of ink, but anyway, all other colors are used to supplement the shortage of three primary colors. Any complex color, always change within the range of three primary colors, as long as you grasp this principle, adjusting the ink is not a problem. When the color analysis determines the primary color and auxiliary color ink and proportion, it can be deployed. However, if the deployed color phase is biased, the supplementary color theory can be used to correct the color phase. For example, the color green is heavy, can add a small amount of red ink to correct. Otherwise, brown is too heavy can be added with blue ink to correct.
3.Intermediate and compound inks matching.
The so-called intercolor is made of two primary color ink mixing. For example red and yellow after the color is orange; yellow and blue after the color is green; red and blue to purple. In two matches, you can deploy a variety of intercolors. Nam: original color peach and yellow in 1:1 mix, can get big red phase; if 1:3 mix can get dark yellow; if 3:1 mix can get gold red phase. Green if the original color is yellow and blue; emerald green if 3:1; apple green at 4:1; dark green if 1:3.If the original peach and blue are mixed with 1:3, you can get the dark blue and purple, if the 3:1 mix can get the approximate green lotus color. The compound color comes from the three kinds of primary color ink mixing and deployment. If they mix in different proportions, you can get many kinds of complex colors. Original peach, yellow, and blue, almost black; peach, yellow and blue, red-brown; l, yellow and blue, olive; peach, yellow, four blue, dark green, etc.
4. Method of allocating ink
When we mix the inks, we should analyze the color phase according to the original draft. For example, making the lake blue ink, it can be mixed successfully by observation, and practical experience. Among them, white ink is the main color, and peacock blue is the auxiliary color that should be slightly added. If you want a deeper color, then add blue. If you want to adjust the olive-yellow and green ink color, you can be determined to be mainly white ink, add light yellow and peacock blue and slightly add peach red can be. As long as the main color is determined, the other colors are auxiliary colors, which should be gradually traced added to stir evenly. Then, using two pieces of small material (the same as the printing material) one coated with some ink, with the other piece to the thickness of the printed ink, that is, the appropriate compared with the original draft. To the same draft, to the scratch type ink layer relatively thin and light parts, to see some accurately. When adjusting ink, we should master a principle, that is, use as little ink of different colors of ink as possible, that is to say, can with two kinds of ink adjustment, do not use three kinds of ink to adjust, so as not to reduce the gloss of the ink. On the other hand, the ink color deployment of the scratch sample is slightly darker than the original color, so that the printed color sample can be accurate. After the ink color adjustment of a small sample, batch ink adjustment can be conducted according to their respective ink proportion to ensure the quality of ink adjustment and improve work efficiency
To sum up, as long as we master the change rulers of the three main colors, apply good color knowledge, seriously practice and analyze, and summarize. We will be able to quickly and accurately match color ink, bright color, bright and good printing adaptability, to lay a solid foundation for improving the quality of silk printing
