Screen printing screens that are not used in the screen printing industry require different tensions.
The screen printing mesh uses dot printing. In order to ensure the accuracy and reproducibility of the tone value. A tension of 20-30 N/CM is required. Fine silk screen prints, scale dials, etc., tension is 12-18N/CM. General graphic printing, tension is 8-12N / CM. Manual printing, rough printing products, or for precision, size, etc., the tension is 8-12N/CM. It is worth noting that when the color block is overprinted, in order to make the overprinting position accurate, not only the screen tension should be greater than 10N/CM. And several sets of overprinted plates must reach the same tension, which is more important for dot printing, otherwise it will cause deviations of moiré and hue.
When you use it, your friends will have a problem. Why do dot printing require high tension mesh templates?
1. The higher tension mesh version can obtain a lower mesh distance. When the mesh distance is doubled, the deformation of the printed graphic will be increased by 3 times. Therefore, when the tension of the mesh is low, the ink is uneven and the dots are Increase distortion and affect color uniformity.
2, the small scraping pressure, is conducive to avoid the ink around the dot, deformation, improve the sharpness of the edge of the dot, and ensure the printing effect.
3, lower grid spacing, screen printing can use less pressure on the screen version, the screen version wear reduces the life of the screen and prolongs the printing times.
The above is the tension requirement of the screen printing screen. If you don't understand it. Or if you want to buy a high quality printing mesh, please contact the brand manufacturer maishi Group.
