You can cure plastisols on a heat press, just adjust the clamp so it's about an inch off the shirt. The heat is there. You just wouldn't want to touch the ink with it.
That's what I luv about this place. You literally learn something new every day.Heat presses can fully cure a plastisol print in 15 seconds at 320 degrees. The cure from a heat press is as good as any other heat method.
