Supacolor Blocker Transfers – Sublimated or Patterned Polyester Fabrics

Supacolor Blocker Transfers for Sublimated & Patterned Polyester

Supacolor Blocker transfers are engineered to stop dye migration — the bleed-through that ruins prints when you decorate sublimated or patterned polyester. A built-in blocking layer traps the garment’s dyes so your colors stay true and your finished pieces don’t turn pink, gray, or muddy after pressing.

If you’re printing on dye-sublimated jerseys, patterned poly, or any fabric you suspect might bleed, the Blocker transfer is the safe choice. It delivers the same vibrant, durable, full-color Supacolor finish — with the added insurance of migration protection that saves garments and reprints.

What Are Blocker Transfers For?

Use Blocker any time the garment’s own dye could migrate up into your print — most commonly on sublimated or patterned polyester. If your fabric is a softshell, use the Softshell Blocker, which is tuned for that material. For standard cotton and blends with no migration risk, Wearable or SupaDTF will be more economical.
