Brush product color saturation processing method

　　1. The depth of the basic primary color is sufficient

　　1) Make various solid color blocks, such as red, green, blue and other colors, such as headers and logos, and deep basic colors that do not require layers. Generally, customers require strong and vivid colors for these headers and logos. . In theory, it is to maximize the maximum solid density of offset ink to achieve maximum saturation. Although 95% of the dots will increase to 100% after printing, this is not the same as 100% solid printing. 95% of the dots have a density of 95% in the dot area, and the increase is 5 Although the % area has ink, the ink density is thin. 95% of the dots are increased to 100% and the ink density is not as thick and bright as 100% of the solid density.

　　2) The blue sky, ocean, green leaves, lawn and other colors in the landscape photography image, because the fixed concept has been formed in people's minds, therefore, in principle, the color quantity of the C version should be deepened on the basis of the required color quantity of the hue. Some, while the green leaves, lawns and other green, the Y version is also, so that the green is saturated and bright. For the basic colors of red, green and blue depths required, according to the color shift and ash characteristics of general offset inks, the optimal saturation configuration is:

　　Red = M95% + Y85%

　　Green = Y95% + C85%

　　Blue = C95% + M80%

　　3) The configuration of the dot value of the blue sky: First, the Y color is not placed below 40% of the C color plate to make the sky blue more beautiful; the second is to put some Y color in the C color version above 50% to make the sky blue Do not make red, but make the blue calm and thick. At the same time, because the sky blue ink used now is reddish, it is consciously light red, which makes the blue sky more beautiful.

　　4) The autumn red leaves of Xiangshan can be treated more red than the actual red leaves. The depth basic color Y is 100%: M is 95%, C can not be placed, making the red leaves appear extraordinarily gorgeous under the sunlight, giving a kind of pleasure. The sense of transparency.

　　The above-mentioned change in color pursuit breaks through the traditional color matching method and highlights the aesthetic value of color in visual art.

　　2. Depth basic color maintains the level

　　1) The depth of the basic color of the dot tone value range is 65% to 90%, because 80% increase the number of Internet points, the level is easy to level. Therefore, for this area, the basic color of the hierarchy is needed. Under the premise of emphasizing the density of the field, the level should be maintained, and the density of the field should not be emphasized, and the level of the basic color should be leveled. The essentials of processing: the depth of the basic color of the required level, the focus is that the amount of color in the area above 80% is moderately reduced, so that it can be separated from the solid color block, so that printing can not only print the density of the field, but also maintain the level. .

　　2) In the color processing, the vivid saturation of the color and the light and dark levels in the color are difficult to balance. To preserve the light and dark levels in the color, it is necessary to use complementary colors, and the complementary color is used in Shenzhen packaging and printing. The degree will decrease and the gray level will increase. To make the color bright, it is necessary to put less complementary colors, so that the light and dark levels in the color will be affected. For timeliness and packaging products, emphasis should be placed on the saturation of color, which affects the shade of some colors. In this way, the final printed image has a strong color sense and a good visual effect. The key is to master a "degree", and the "degree" is the performance of the operator's aesthetic level, directly related to the color art effect.

　　3) The layered texture in the deep basic color is mainly expressed by the main color version, such as red, orange and other warm colors: it is expressed in Y and M color versions; such as green, cyan and other cool colors, represented by C color version. Therefore, it is necessary to emphasize the hierarchical texture of the main color version, and realistically express the characteristics of the physical layering.

　　4) The basic color of the middle adjustment area is sufficient. The mid-range area has a range of 35% to 65%, which is the main part of most objects and is the key area for color processing. To adjust the basic color of this area to the optimal saturation, the method is based on the amount of color required for the hue. Further increase by about 5%, such as safflower, the color of the bright and medium tone needs 40%. It can be deepened to 45%, making red more saturated and bright.
