Screen printing failures and countermeasures--film cracking

Eleven, ink film cracking

The cracking of the ink film is caused by the effect of the solvent and the large temperature change. Substrate material itself can also cause ink film cracking.

In order to prevent the occurrence of ink film cracking, the nature of the ink, the substrate, and the solvent resistance should be taken into consideration when selecting the solvent. Use solvent-resistant and oil-resistant materials as printing materials, and pay attention to maintaining a balanced shop temperature. In multi-color overprinting, it is necessary to fully dry each color after printing, and strictly control the drying temperature to effectively prevent ink film turtles. Cracking occurs.
