Four-Color Process Screen Printing is a method of printing that uses four colors (Cyan, Magenta, Yellow, and Black) to produce full-color images.
1. Four-Color Process Screen Printing
Cyan, Magenta, Yellow and Black are also called Process Colors and are used in Four-Color Printing to reproduce other colors.

Some colors such as green and orange are especially difficult to reproducing in the CMYK model. If you want that green and orange were brighter and saturated, they can be printed as additional Spot Colors.
Fluorescent and metallic colors cannot be printed by mixing of four process colors. These colors also should be printed as additional Spot Colors.
Four-Color Process for silk-screen printing differs from traditional offset printing.
The following table shows the basic differences between printing technologies.
