By mixing yellow, magenta and cyan inks in different proportions, different colors of inks can be obtained. Therefore, yellow, magenta and cyan inks are called the three primary colors of pigments, and the basic rules for ink blending are as follows.

Ink blending refers to the process of mixing one or more inks together and adding certain auxiliary materials to meet the printing needs.

Packaging products often have a large site area. If four-color screen printing is used, printing will be very difficult and color difference will easily occur.

The color formed by mixing two primary inks is called intermediate color, also called secondary color. If two primary color inks are mixed in equal amounts, typical intermediate colors (red, green and blue) can be obtained; If you don't mix in equal amounts, the color you get tends to be the one with a large proportion.

Adding Bai Mo to the middle color will brighten the color; When black ink is added with intermediate color, it will become dark.
