How to maintain the service life of the screen printing screen
1. Since the screen printing mesh is glued to the frame (whether it is a wooden frame or a metal frame), the angle 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 sealed with glue; it prevents the ink or other solvent from penetrating into it and causes the mesh to slack or fall off.
2. When using the screen, you should keep the screen spacing, which is known to everyone. At this time, the pressure of the printing scrape should not be too heavy; at the same time, the distance between the ink returning sheet and the screen can not be close to prevent the 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, and the squeegee blade should not be too profitable; a layer of adhesive tape should be attached to the position where the squeegee blade is in contact with the screen to prevent it from being worn.
3. The used screen must be cleaned and cleaned with a special solvent, especially in places with patterns, but not too hard; ensure that the pattern is transparent. Place the cleaned screen in a dry, ventilated place, taking care to prevent dust.
4. The mesh must be cleaned and degreased before use. If the corresponding degreasing work is not done, the screen will be delaminated or destroyed during the printing process.
Poor ink circulation and web stripping are two direct reasons for screen replacement. If properly maintained, it will reduce the problem during the printing process, so that the screen can not only withstand thousands of printing, but also extend the service life. Marking the number of meshes and the age of the mesh on the frame is also a good way to ensure normal screen printing. In addition, choosing the right frame, mesh, and reasonable maintenance will make the screen printing work more effective.
