Set Temperature and Time
- 290F (140C)
- 10 Seconds

Load a Test Polyester Garment
If possible, slip the platen through the shirt so there is only one layer of fabric on top. Otherwise, lay shirt on top of the platen. Avoid pockets if possible.

Set Pressure
- Manual Press: Tighten dial until the press won’t close. Loosen dial progressively until the press closes, use less pressure for polyester.
- Hotronix and Geo Knight: 7-8
- Pneumatic Press: 35-40 PSI

Pre Press: None
100% polyester does not hold moisture, so should not require a prepress unless you just need to smooth out the fabric for 2 seconds

Place Supacolour
Place Supacolour transfer on the garment. Lay a teflon sheet or parchment paper over the Supacolour.
6
Press 8-10 Seconds
7
Peel Immediately
Hot peel immediately from a corner in one smooth motion. Peel with confidence and without hesitation. Hold down shirt with your free hand for better control.

Post-press: 2-4 Seconds
Use a teflon sheet or parchment to seal the edges of the Supacolour.
- Always test press on a spoiled or old polyester garment to dial in your press before pressing your production.
- Supacolour always gives you spares so you can dial in your press.
- Supacolour not sticking when you peel? Increase pressure and peel quickly within 2 seconds of lifting press, keep transfer a clear distance from pockets and seams.
- Still won’t peel easily? Repress for 4 seconds then try from a different corner.
- Color changing after pressing? Order [BL] Blocker. These come with a blocking layer to stop dye migration from dyed or sublimated polyester garments!
- These instructions are your default starting point, settings may vary for different garments and presses.
