How to Depth basic primary color?

1) The various field color blocks, such as red, green, blue and other colors of the masthead and logo patterns and do not need to level the depth of the basic color, the general customer for these masthead and logo pattern colors, are required to be strong and bright. Theoretically speaking, it is to give full play to the extreme effect of the maximum field density of offset printing ink to achieve maximum saturation. Although 95% of the outlets will increase to 100% after printing, this is not the same as the effect produced by 100% field printing, 95% of the outlets only reach the density of the field in 95% of the dot area, and the increased 5% area although there is ink, but the ink density is thinner. 95% of the dot increase to 100% ink density is not as thick and bright as 100% field density.

2）The color of blue sky, ocean, green leaves, lawn and other colors in landscape photography images, because it has formed a fixed concept in people’s minds, therefore, in principle, the color amount of the C version should be deepened on the basis of the color amount required by the hue, and the green leaves, lawns and other green, then the Y version is also saturated and bright green. For the basic color of red, green and blue depth that needs to be layered, according to the color bias and gray characteristics of the general offset printing ink, the optimal saturation configuration is:

red =M95%+Y85%

green =Y95%+C85%

blue =C95%+M80%

3) The dot value configuration characteristics of the azure blue sky: first, it does not put Y color below 40% of the C-color version, making the sky blue more beautiful; The second is to put more than 50% of Y color in the C-color version, so that the sky blue does not run red, but also makes the blue calm and thick. At the same time, because the sky blue ink used now is red, it is consciously reduced to light red, so as to make the azure sky more beautiful.

4）Autumn Xiangshan red leaves can be treated a little redder than the actual red leaves, the depth of the basic color Y is 100% : M is 95%, C can not be put, so that the red leaves in the sun, it is particularly beautiful, giving people a pleasant sense of transparency.

The above changes in the pursuit of color break through the traditional method of color matching and highlight the aesthetic value of color in visual art
