You can understand this by screen printing: it is like having a circular hole in the paper. Place it on the table, then sweep over the paper with a large ink-filled brush to remove the paper.

This is the realm that screen printing can achieve now. . What is its specific principle?
The working principle of the clothing T-shirt screen printing mesh: evenly apply the adjusted photosensitive material on the already fixed screen, and then prepare the designed pattern to be printed out through the transparent paper; apply the blackening agent on the printed pattern. To make the black and white contrast more intense. The printed pattern paper is attached to the screen which has been exposed to the photosensitive material, and the whole screen frame is placed in a professional exposure machine, and the black pattern is exposed through a professional GaN lamp to deposit gallium in a dark room environment. The lamp illuminates and decomposes with light; the black part blocks the iodine gallium light line, no reaction occurs, the mesh is soluble in water, leaving a net on the wire mesh; otherwise, the rest of the screen is penetrated by the iodine gallium lamp and sensitized The material reacts and the mesh is blocked.
Remember to note that after using the T-shirt screen printing mesh, you still need to wash it for a long time. Otherwise, it will be troublesome next time. It was used up at the time and washed at that time
