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.
The methods and methods are as follows:
1. Depth basic color to do enough
1) Make sure that all the color blocks in the field, such as red, green, blue and other colors, and the depth of the basic colors do not require the depth of the basic color, the general customers of these header and logo color, require a bright . 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 a level, the best saturation configuration for general offset inks is: 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.
