1) The depth basic color of the dot level adjustment value range is 65% to 90%, because more than 80% of the dot increase, the level is easy to level. Therefore, layers of basic colors are required for this area. The level should be maintained on the premise that the field density is sufficient, and the field density saturation should not be emphasized, resulting in the level of the basic color. Processing essentials: The basic color of the depth of the required level, the focus is on the color amount of more than 80% of the area to be moderately lightening, so that it is separated from the field color block, so that the printing can print the field density, and maintain the level.
2) In the color processing, the bright saturation of the color and the level of light and dark in the color are difficult to take into account, if you want to preserve the level of light and dark in the color, it is necessary to use complementary colors, and the complementary colors are used, the brightness of the color will be reduced, and the gray level will be increased. If you want to make the color bright, it is necessary to put less complementary colors, so that the level of light and dark in the color will be affected. For timeliness and packaging products, the saturated and bright color should be emphasized, affecting the light and dark levels of some colors. In this way, the final printed image has a strong sense of color and good visual effect. The key lies in mastering a “degree”, and the grasp of “degree” is the expression of the operator’s aesthetic level, which is directly related to the effect of color art.
3) The layered texture of the depth of the basic color is mainly expressed by the main color plate, such as red, orange and other warm tones: it is expressed by the Y and M color plate; Cool colors, such as green and cyan, are represented by the C-color version. Therefore, it is necessary to emphasize the hierarchical texture of the main color plate and realistically show the characteristics of the physical layer
4) The basic color of the middle tone area is sufficient. Medium tone area dot level value range of 35% to 65%, which is the main part of most objects, is the key area of color processing. To adjust the basic color of this area to the optimal saturation, the key is to rely on the amount of color required for the hue. Deepen about 5%, such as safflower, its bright tone of the M color needs to be 40% of the color, can be deepened to 45%, so that the red is more saturated and bright.
