How to make sure your prints are fully cured
- Measure the ink, not the dryer setting. The whole ink film must reach cure temperature, not just the surface. Use temperature strips or a probe on the shirt as it runs through the dryer.
- Slow the belt before you raise the heat. Thick deposits (white underbase, puff, high density) need more time in the heat, not just more heat.
- Polyester and blends: use low-cure, low-bleed ink. Dye migration starts as polyester gets hot, which is why low-cure inks such as Epic Rival Sport and Low-Bleed Poly exist.
- Stretch test. Stretch a cooled print; if it cracks or the ink lifts, it is under-cured.
- Wash test the first shirt of a new job.
Equipment that holds steady cure temperatures: automatic presses, Vastex conveyor dryers such as the LittleRed X1-30 ($4270.00), EconoRed II-30 ($8374.00) and BigRed 4D-30 ($16759.00), and flash units like the ROQDry Evolution 9000 M quartz flash ($5725.00).

Frequently asked questions
What temperature does plastisol ink cure at?
Most standard plastisol cures at about 320–325°F (160–163°C) through the full ink film. WM Plastics All Purpose lists 325°F for 1 to 1½ minutes.
What is a low-cure plastisol ink?
Low-cure inks cure at lower temperatures to stop dye migration on polyester. Wilflex Epic Rival Sport cures at 250–300°F and WM Plastics Brute White at 230°F.
What flash temperature should I use?
Flash only until the ink is dry to the touch (gelled). Wilflex lists 220°F for Epic Rio and 160°F for Epic Rival Sport.
How do I know if my print is fully cured?
Measure the ink film temperature with temperature strips or a probe, then stretch-test and wash-test a sample shirt. Cracking or lifting means it is under-cured.
What temperature do you press DTF transfers?
Most DTF film and powder combinations press at about 285–315°F with medium pressure for 10–15 seconds, followed by a short post-press.
