Never have to worry about whether you're properly curing your plastisol ink again! Simply shine the laser on an area of ink and ensure that it has reached the proper 320F. If you use a flash dryer to cure your prints, just shine the light onto the print area and wait until the electronic display shows a temperature reading of 320F. If using a conveyor dryer, simply stand at the end of of the conveyor and shine the light on the ink right as it's about to come out of the chamber. If it reached 320F, it's properly cured!
