While modern, synthetic fabrics like polyester are appealing due to their technical capabilities and seemingly limitless design enhancements, they present complex printing issues when heat is introduced. Supacolor Blocker transfers give you the confidence and ability to print on fabrics that are sublimated, dye migrate or have heavy patterns.

Supacolor Blocker Custom Transfers Application Instructions

1. Set Temperature and Time
  • 290F-300F
  • 15 seconds
2. 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.

3. Set Pressure
  • Manual Press: Tighten dial until the press won’t close. Loosen dial progressively until the press closes.
  • Hotronix and Geo Knight: 7-8
  • Pneumatic Press: 35-40 PSI
4. 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.

5. Place Supacolor

Position the transfer on the garment. Lay teflon sheet or parchment paper over the Supacolor.

6. Press 10-15 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.

8. Post-Press: 2 Seconds

Use a teflon sheet or parchment to seal the edges of the Supacolor.
