Science Nursing is divided into 4 points in total, as follows.
1. Since the mesh is glued to the frame by glue (whether it is a wooden frame or a metal frame), the angle of the screen frame should be sealed before using the screen. Generally, plate-making companies will apply one. Layers of glue are either sealed with glue; prevent ink or other solvents from penetrating into the net to cause it to loosen or fall off.
2. When using the screen version, you should keep the screen distance, as everyone knows. At this time, the pressure of the printing scrape should not be too heavy; at the same time, the distance between the ink return sheet and the screen should not be close to prevent friction, which will cause the photosensitive paste to become thin.
The length of the squeegee should be slightly larger than the pattern, generally 15-20mm, the blade edge of the squeegee should not be too profitable; paste a layer of adhesive paper at the position where the blade edge of the squeegee is in contact with the screen to prevent its wear.
3. After using the screen, be sure to clean it up and clean it with a special solvent, especially where there is a pattern, but do not use too much force; ensure that the pattern is transparent. Place the cleaned screen in a dry, ventilated place, taking care to prevent dust.
4. No matter how you pay attention to the screen, it is also a consumable. As time goes by, the tension will change.
