What Heat Press Temperature Is Safe for DTF on Polyester?

BY : Mike DeGroot

Press DTF on polyester at 302°F. The working range is 300 to 320°F, and 320°F is the maximum. Polyester is heat-sensitive, so use a cover sheet and test a spare garment first. If the fabric shines or marks at 300°F, it is not a good fit for DTF.

Why is polyester tricky?

It softens under heat and can show shine, scorching or dye bleed. Cotton forgives more. That is why testing matters more on polyester.

How do I press it safely?

  • Preheat to 302°F
  • Use a Teflon or parchment cover sheet
  • Press a scrap or spare garment first
  • Check for shine, marks and colour change
  • Use a pillow if seams are near the print

What if the garment marks?

Stop and test a different garment. Do not raise the temperature past 320°F. Pink or tinted colour on red polyester is dye migration. See why it happens.

Does temperature change the peel?

Hot peel is our recommendation and cold peel also works.

Quick answers

Can I press lower than 300°F?

Our working range is 300 to 320°F. Test on a spare garment first, and ask us.

What is the max?

320°F.

Order ready-to-press DTF gang sheets and press with confidence.
