Cracking on the surface of the ink layer of screen printing
2024-06-17 08:05:29
Cracks on the surface of the ink layer of the substrate after screen printing are mainly caused by the effect of the solvent and large temperature changes. Generally, styrene substrates may crack with alcohol and petroleum-based weak solvents. Some substrate materials can also cause cracking due to their own factors.
In order to prevent the occurrence of cracks, the nature of the ink and the solvent resistance of the substrate should be considered when using the solvent first, and pay attention to maintaining a balanced temperature in the workshop. In multi-color overprinting, each color should be fully dried after printing, and the drying temperature should be strictly controlled. Generally speaking, by paying attention to the above aspects, the cracking of the ink layer can be effectively avoided.
