1. Sufficient depth of basic primary color


1) All kinds of on-the-spot color blocks, such as red, green and blue lettering and logo patterns, and basic colors that do not need layers of depth, are fully done. General customers require strong and bright colors for these lettering and logo patterns when custom printing china. Theoretically, it is to give full play to the extreme effect of the maximum field density of offset ink to achieve the maximum saturation. Although 95% of the dots will increase to 100% after printing, this is different from the effect of 100% field printing. 95% of the dots only reach the field density in 95% of the dot area, while the increased 5% area has ink, but the ink density is thin. 95% of the dot increases to 100% of the ink density, which is not as thick and bright as 100% of the field density.


2) The blue sky, ocean, green leaves, lawn and other colors in landscape photography images are in people's minds


A fixed concept has been formed. Therefore, in principle, the color quantity of version C should be deepened on the basis of the required color quantity of the hue, while that of version y for green leaves, lawns and so on, so as to make the green saturated and bright. According to the color deviation and graying characteristics of general offset printing inks, the optimal saturation configuration for the basic colors with different levels of red, green and blue depth is as follows:


Red = M95% + y85%


Green = y95% + C85%


Blue = C95% + M80%


3) The dot value configuration characteristics of azure sky: first, do not put Y color below 40% of the C color version to make the sky blue more bright; Second, put more than 50% of the c-color version in Y color to make the sky blue not red, and make the blue calm and thick. At the same time, because the sky blue ink used now is red, it consciously reduces the light red, so as to make the blue sky more beautiful.


4) Xiangshan red leaves in autumn can be treated more redder than the actual red leaves. The depth basic color y is 100%: m is 95%, and C can not be put, which makes the red leaves look particularly gorgeous in the sun and give people a pleasant sense of transparency.


The above changes in the pursuit of color break through the traditional color matching methods and highlight the aesthetic value of color in visual art in custom printing china.


2. Maintain the level of depth basic color


1) The dot gradation of the deep basic color ranges from 65% to 90%. As more than 80% of the dots increase, the layers are easy to merge. Therefore, the basic color of the hierarchy is needed for this area On the premise of emphasizing the sufficient field density, the level should be maintained, and the field density saturation should not be emphasized, resulting in the level and level of basic color. Processing Essentials: the depth of the basic color of the required level, focusing on the color quantity of more than 80% of the area, is moderately reduced to make it a distance from the field color block, so that the printing can not only print the field density, but also maintain the level.


2) In color processing, it is difficult to give consideration to both the bright saturation of color and the light and dark levels in color. In order to preserve the light and dark levels in color, complementary colors should be used. If complementary colors are used for custom printing china (packaging and printing), the brightness of color will be reduced and the gray level will be increased. If you want to make the color bright, you should put less complementary colors, so that the light and dark levels in the color will be affected. For timeliness and packaging products, we should emphasize the saturation and bright colors, which will affect the light and dark levels of some colors. In this way, the final printed image has strong color sense and good visual effect. The key is to master a "degree", and the grasp of "degree" is the expression of the aesthetic level of operators, which is directly related to the artistic effect of color.


3) The layered texture in the deep basic color is mainly represented by the main color plate, such as red, orange and other warm colors: it is represented by Y and M color plates; Cool colors such as green and cyan are represented by the c-color version. Therefore, we must emphasize the hierarchical texture of the main color plate and realistically show the characteristics of the hierarchical feeling of the real object.


4) the basic color of the middle adjustment area is adequate. The range of tone adjustment in middle adjustment area is 35% 1 65%, which is the main part of most objects and the key area of color processing. To adjust the basic color of this area to the best saturation, the key is based on the amount of color required for the hue About 5% more, for example, safflower, its bright M color needs 40%, and it can deepen the processing to 45%, and make the red more saturated and bright.
