Although the screen printing screen is a consumable, but we keep its function to a minimum in daily use, we can properly extend its life.
What we can do is the following 4 points.
1. The used screen must be cleaned up and cleaned with a special solvent, especially where there is a pattern, but not too hard; ensure that the pattern is transparent. Place the cleaned screen in a dry, ventilated place, paying attention to dust.
2. When using the screen printing 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-returning film and the screen should not be close, to prevent its internal 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 larger, the blade of the squeegee should not be too advantageous; put a layer of adhesive paper on the position where the blade of the squeegee is in contact with the screen to prevent its wear.
3. Since the mesh is glued to the frame by glue (whether it is a wooden frame or a metal frame), the corners of the inner frame of the screen should be sealed before using the screen; the general plate-making company will apply one The layer of glue is either sealed with glue; preventing ink or other solvents from penetrating into it, causing the mesh to relax or fall off.
4. How to pay attention to the screen is also a consumable. After a long time, the tension will change. The above 3 points can only reduce energy damage.
5. We also have an important point to purchase high-quality printing meshs before using. Good quality printing mesh can guarantee its service life itself is a little longer.
The products of regular screen printing mesh manufacturers are absolutely guaranteed. We can choose.
