The importance of color matching in album printing!
In the process of album printing, an important link is album printing color matching. The accuracy of a printing master's grasp of product color is related to the quality of product printing.
In the pre production, due to the RGB gamut space is larger than CMYK, so before the official transfer to printing, it is processed in RGB mode, of course, you can also use lab mode, but the default is RGB mode. Why do you want to do this conversion? It is because RGB three colors belong to the three primary colors of light, in line with color addition; while CMYK is ink four primary colors, in line with color subtraction, in fact, black ink can not be counted as primary color, but it is generally used to replace the mixture of other three colors. Intuitive performance is the same image, CMYK mode is relatively dark.
The allocation of ink is an important work in color printing process. How this work is done is directly related to the printing quality of product album. Because bright color, good brightness and accurate hue are the basic requirements of color printing products. To achieve this requirement, it is necessary to accurately allocate printing ink. Therefore, the operator should master the color knowledge and inking process.
Master the changing law of the three primary colors, so as to realize the accurate ink mixing: any color can be mixed with different proportions of the three primary colors, and the color change of the ink is exactly using this law. Such as three primary color ink mixed after deployment can become black (approximate). Three primary color ink mixed with the same amount and add No
The same proportion of white ink, you can match a variety of different tones of light gray ink.

If the three primary inks are mixed according to various proportions, they can be blended into a variety of intercolor or multicolor of different hues, but the hue tends to the primary color with large proportion. If two kinds of primary color inks are mixed in equal amount, they can become standard intercolor; after mixing and mixing the two primary color inks according to different proportions, they can be matched into a variety of intercolor with different hues, but the hue tends to be the primary hue with large proportion. In addition, any color of ink, after adding white ink, its hue appears more bright. On the contrary, after adding black ink, its hue becomes deep.
Analysis of the original color: use the complementary color theory to correct the color deviation and improve the ink mixing effect. After receiving the color draft of the picture album, first of all, carefully appreciate and analyze the various colors in the original, and master a basic principle, that is, the three primary colors are the basic colors for the deployment of any ink color. Generally speaking, the application of three primary color change law, in addition to gold and silver color, any complex color can be blended out.
However, in the process of process practice, it is not enough to rely on the three primary color ink to allocate countless ink colors. Because, in fact, the production of ink pigment is not very standard, and even each batch of ink in the color inevitably there is a certain degree of difference. Therefore, in the actual work should also be used such as blue, dark blue, light blue, light blue, yellow, dark yellow, light yellow, golden red, orange, dark red, light red, black, green and other inks to be added appropriately, in order to achieve the required ink hue. There are many kinds of ink, but no matter how, in addition to the primary color ink, other colors are used to supplement the three primary colors. Any complex color, always changes in the range of three primary colors, as long as you master this principle, inking is not a problem. When the color analysis to determine the main color and auxiliary color ink and proportion, can be mixed. But if there is deviation in the hue, the complementary color theory can be used to correct the hue.
