(1) In some places, the ink layer is thick, and in some places, the ink layer is thin and the thickness is not uniform.
(2) The pattern text is distorted.
(3) Local graphics may be blurred.
(4) When the dot is printed, the dot is deformed or misaligned, resulting in color shift.
What is the size of the mesh distance under normal tension?
(1) First, the mesh distance is large, the scraping pressure of the scraper is large, and the screen is prone to premature aging (the screen tension loss is large).
(2) The mesh distance is small, and the screen cannot be immediately detached from the workpiece, so that the pattern is dirty.
Therefore, in the case of a certain tension of the screen, it is necessary to ensure that the scraping pressure is minimized during the silk screen printing process and the screen can be immediately detached from the workpiece.
