In the process of card game printing wholesale and album printing, an important link is the color mixing of card game printing wholesale. Whether a printing master grasps the color of the product accurately or not is related to the quality of the product printing. How to better grasp the color in printing, let's understand several aspects together.

In the pre-production, because the RGB gamut space is larger than CMYK, it is processed in RGB mode before being officially transferred to the printed piece, of course, you can also use Lab mode, but the general default is RGB mode, why do you want to convert it? Because RGB three colors belong to the three primary colors of light, in line with color addition; CMYK is the ink four primary colors, in line with color subtraction, in fact, black ink can also not be the primary color, but it is generally used to replace the other three color mix. Intuitive performance is the same image, CMYK mode is relatively dark.

Deployment ink is an important work in the color printing process, how to do this work, directly related to the quality of the product card game printing wholesale, because bright colors, good brightness, accurate color printing is the basic requirements, to achieve this requirement first accurately deploy printing ink. Therefore, the operator must master the color knowledge and ink mixing process.

Master the three primary color change law in order to achieve accurate ink allocation; Any color can be mixed into different proportions of the three primary colors, and the hue of the ink changes, officially using this law. If the three primary color ink is mixed with the same amount, it can become black (approximate). The same amount of three primary color ink and adding different proportions of mixing, can be deployed into a variety of different colors of the intermediate color or compound color, but the color tends to the proportion of the large primary color; After the two kinds of original color demons are mixed and deployed in different proportions, they can be matched into a variety of different colors, but the color tends to be a large proportion of the primary color hue, in addition, any color ink, after adding ink, its hue appears brighter. On the contrary, after adding black ink, its hue becomes darker.

Analysis of the original color: the use of complementary color theory to correct the color bias, improve the effect of ink when receiving the propaganda printing color manuscript, the first should be a careful appreciation and analysis of the various colors in the original manuscript, master a basic principle, that is, the three primary colors are the basic colors of any ink. In general, the application of the change law of the three primary colors, in addition to gold and silver color, any complex color can be deployed. However, in the process of process practice, it is not enough to rely only on the three primary colors to deploy countless ink colors.

Because, in fact, the pigment for manufacturing ink is not very standard, and even each batch of ink produced is inevitably different in color to a certain extent. Therefore, in the actual work should also use medium blue, dark blue, light blue, light blue, medium yellow, dark yellow, gold red, orange red, dark red, black, green and other ink appropriate to add, in order to achieve the required ink color, ink types are many, but in any case, in addition to the three primary colors magic, other colors are used to supplement the lack of three primary colors.

Any complex color, always change in the range of three primary colors, had to master this principle, ink is not a problem, when the color analysis to determine the main color and auxiliary color ink and proportion, you can be deployed, but if the deployment of the color deviation, the complementary color theory can be used to correct its hue.
