How to identify the color of the printing plate?

In the current printing industry, the printing department usually prints Y, M, C, and BK symbols on the back of the printing plate to print yellow, red, blue, and black prints. In addition to this, you can use the dot angle and layout shades to identify plate colors.

1 dot angle discrimination method: When the original color is decomposed, different halftone angles are used for the printing plate images of each color. Therefore, the angle of each dot represents a color printing plate, and the general yellow plate is 90°. , Magenta or Blue with a 45° (or 75°) black version with 15°.

2 Graphic shades contrast discriminating method: to distinguish the shades of the printing plates by comparing the shades of the plate layout with the proofs (or manuscripts) in the same position.
