How important to FULLY CURED Plastisol ink?

8/23/2016

Failure to cure ink properly can result in poor wash fastness, inferior adhesion, unacceptable durability and increased likelihood of dye migration. 

Maximum ink tensile strength and elongation is accomplished by ensuring total fusion of the ink film. Testing procedures include wash testing and testing with solvent, with wash testing being the more reliable method. 

To cure plastisol inks the ink film must reach appropriate cure temperature. A heat history includes time and temperature used to reach total fusion or cure in ink. This cure or fusion is instantaneous once the entire ink film hits the cure temperature (320°F/160°C).
