How to match saturation is an important part of color processing, and the timeliness and packaging products are particularly emphasized on the degree of saturation of the color, to an excessive extent, so that the color has a strong visual impact, in order to satisfy the viewer's appreciation and pleasure. In color processing, some screens can enhance the color of another part or the main part based on the equal compression of various colors or the loss of a certain part of colors, and some pictures can balance the saturation of all colors according to the original content and the main body. Optimal treatment of color conditions. The methods and methods are as follows:
1. Depth basic color is enough 1) Make all kinds of solid color blocks, such as red, green, and blue color header characters and logos, and do not need the depth of the basic color to do the full, general customers of these header words and signs Pattern colors require thick and bright colors. In theory, it is the maximum effect of the maximum solid density of offset ink to achieve maximum saturation. Although 95% of the printing sites will increase to 100% after printing, this is not the same as the effect produced by 100% on-site printing. 95% of the printing sites only reach the actual density in 95% of the dot area, and the increased number is 5. Although the % area has ink, the ink density is thin. The 95% dot gain to 100% ink density is not as thick and bright as 100% solid density.
2) The colors of blue sky, ocean, green leaves, and lawn in the landscape photography image have been fixed in people's minds. Therefore, in principle, the amount of color in the C version should be deepened based on the amount of color needed in the hue. Some green leaves and lawns are green, and the Y version is also green and bright. For the red, green, and blue depth base colors that require the level, the best saturation configuration is based on the color shift and ash characteristics of general offset inks:
Red = M95% + Y85%
Green = Y95%+C85%
Blue = C95% + M80%
3) Configuration features of sky-blue sky points: Firstly, 40% or less of the C-color version will not contain Y color, making the sky blue brighter; second, put some Y color at 50% of the C color version to make the sky blue Do not take the red, and make the blue calm and thick. At the same time, since the sky blue ink now used is reddish, the light blue is consciously reduced, making the sky blue more beautiful.
4) The autumn leaves of Xiangshan Mountain can be treated more reddish than the actual red leaves. The basic color Y is 100%: M is 95%, and C can hold it, making the leaves in the sun shine, it is extraordinarily gorgeous, giving a joy The sense of transparency.
The above-mentioned changes to the pursuit of color break through the traditional color matching methods and highlight the aesthetic value of color in the visual arts.
2. Depth basic color retention level 1) The range value of the dot depth of the basic color is in the range of 65% to 90%. Since the 80% increase in the Internet point is more, the level is easy to merge. Therefore, the basic color of the hierarchy is needed for this area. The emphasis should be on the premise of emphasizing the fact that the density of the field is relatively sufficient, and maintain the level among them. The intensity of the density of the field cannot be emphasized, and the level of the basic color level can be achieved. Treatment essentials: The depth of the required level of basic colors, the focus is more than 80% of the color of the area for the appropriate lighten, so that it is a distance away from the field color, so that printing can not only print the full density, but also to maintain the level of .
2) In the color processing, the vivid saturation of the color and the light and shade levels in the color are difficult to both take into account. To preserve the light and shade levels in the color, complementary colors are used, and complementary colors are used. The vividness of the colors will be Decrease, increase grayscale. To make the colors colorful, complementary colors should be placed less, so that the light and shade levels in the colors will be affected. For timeliness and packaging products, emphasis should be placed on the saturated color of the color, affecting the light and dark levels of some colors. In this way, the color impression of the final print image is strong and the visual effect is good. The key lies in mastering a "degree", and the grasp of "degree" is the performance of the operator's aesthetic level and is directly related to the effect of color art.
3) The texture of the depth in the basic color is mainly expressed in the main color version, such as red, orange and other warm colors: it is expressed in Y, M color version; such as green, cyan and other cold colors, expressed by the C color version. Therefore, we must emphasize the hierarchical texture of the main color version, and realistically display the characteristics of physical layering.
4) The basic color of the intermediate tone area is sufficient. The tone of the mid-range area is in the range of 35% to 65%. This 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 essentials are based on the amount of color needed for the hue. Deepen 5% or so again, such as safflower, its bright midtone M color needs 40% of color, deepening treatment can be 45%, making red more saturated and bright.
