Screen printing machine is a kind of machine that can print a lot of medium colors on the product, and it can often be seen in our lives, like the various pattern colors on the clothes, the various color patterns on the paper, etc. Then do you know how they are printed? Then, from the principle of color printing of screen printing machines, let's share the principle of color printing of screen printing machines.

Through the following points to share the principle of color printing of screen printing machine:

1. In color printing, the layering and color of the original are completed by the overprinting of the dots of each color;

2. In the color synthesis, the arrangement of the dots will be juxtaposed, superimposed, etc., but the color of the dots themselves on the printed matter will cause the subtractive method to be colored;

3. When the juxtaposed dots or the superimposed dots are mixed or not completely overlapped, the principle of additive color mixing is observed by the human eye. Therefore, the principle of color reproduction of color prints by juxtaposition and superposition of dots is first subtractive (printing on paper) and post-additive (observed by human eyes);

4. According to the principle of dot juxtaposition and superimposed color reproduction, it is known that the amount of ink absorbed by the ink, the thickness of the ink layer, the color density of the ink, and the order of printing all affect the effect of color reproduction;

5. In order to make the three primary colors inks appear to be correctly gray with different brightness, so change the dot synthesis ratio and the amount of ink of the three primary colors of ink, and realize the gray balance is the basis of the color reproduction.
