Silk screen printing cracks on the surface of the finished ink layer

The cracking of the surface of the ink layer of the substrate after screen printing is mainly caused by the effect of the solvent and the large temperature change. General use of styrene printing materials using solvents such as alcohol and petroleum solvents can also cause cracking. 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 taken into consideration when the solvent is used first, and the temperature in the workshop must be kept balanced. In multi-color overprinting, each color should be fully dried after printing, and the drying temperature should be strictly controlled. In general, paying attention to the above aspects can effectively prevent the occurrence of ink layer cracking.
