Get recommended heat press time, temperature, and pressure settings based on your vinyl type and base fabric.
Frequently Asked Questions
Why does polyester need a lower temperature?
Polyester scorches or melts at high heat, so most HTV manufacturers recommend reducing temperature by 15-20°F for poly and blended fabrics.
Do multiple vinyl layers need more time?
Yes, each additional layer needs a few extra seconds of press time to fully bond, though you should always press each layer separately when possible.
Is this a substitute for the vinyl manufacturer's instructions?
No — always check your specific vinyl brand's spec sheet first, since formulations vary. This calculator gives a general starting point.
