How to deploy printing inks in color printing process?
How to adjust the printing ink in the color printing process? The following will be introduced by printers in China:

1.Master the change law of the three primary colors in order to achieve accurate ink blending

We know that any color can be mixed and adjusted by using the different proportions of the three primary colors, and the hue of the ink changes by using this law. For example, the three primary color inks can become black (approximately) after being mixed and blended in equal amounts. The three primary color inks are mixed in equal amounts and added with different proportions of white ink to form a variety of light gray inks with different tones.
If the three primary color inks are mixed in various proportions, they can be mixed into a variety of inter-colors or multiple colors of different hues, but the hue is biased toward the primary color with a large proportion. If the two primary color inks are mixed in equal amounts, they can become standard secondary colors; after the two primary color inks are mixed and mixed in different proportions, they can be mixed into a variety of secondary colors with different hues, but their hue tends to be the primary color with a large proportion. In addition, in any color ink, the hue appears brighter after adding white ink. On the contrary, after adding black ink, its hue becomes darker. The above-mentioned blending of primary color inks into various colors is based on the theory of subtractive color of the three primary colors.

2.Analyze the hue of the original manuscript

Use complementary color theory to correct the color cast and improve the effect of ink adjustment. After receiving the printed color manuscript, you should first carefully appreciate and analyze the various colors in the manuscript, and think about 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 ink color. Generally speaking, using the changing laws of the three primary colors, any complex colors can be deployed except for the colors of gold and silver. However, in the process of technological practice, it is not enough to use the three primary color inks to mix countless kinds of ink colors. Because, in fact, the pigments used to make inks are not very standard, and even the colors of each batch of inks inevitably have a certain degree of difference. Therefore, in actual work should also be used such as medium blue, dark blue, light blue, light blue, medium yellow, dark yellow, light yellow, golden red, orange red, deep red, light red, black, green and other inks should be added in an appropriate amount, In order to achieve the required ink hue. There are many types of ink, but no matter what, in addition to the three primary colors, 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 this principle is mastered, the ink adjustment will not be a problem. After the color analysis determines the main color and the auxiliary color ink and the proportions, it can be mixed. But if the mixed hue is deviated, the complementary color theory can be used to correct its hue. For example, green ink is too heavy, which can be corrected by adding a small amount of red ink. On the contrary, if the red smell is too heavy, add blue ink to correct it.
