For us on sublimaed or patterned polyester fabrics where there is potential to migrate.
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.
We combine a high opacity white water-based ink along with our special bleed resistant blocking formula to give our Blocker transfers a powerful, high dye inhibiting capability that is second to none. As an added benefit, these transfers do have good stretch capabilities making it an ideal fit for active sportswear that demand both bleed blocking and elasticity from a high-performance transfer. While using low temperature transfers can create a low bleed a scenario, only a true no bleed transfer like Supacolor Blocker transfers can completely block the capacity of the ink and preserve the integrity of your designs.
Not sure if you need to use our Blocker transfer? Use a Supacolor Test Transfers to a fabric in question to test for migrations issues. If the dye is unstable, you will see the results on the strips. Migration is not always immediately visible and can occur days after heat printing. Due to this, we recommend that you allow the transfer to rest for 4-5 days after pressing to confirm result of the test.
Experience how Supacolor Blocker transfers can elevate your printing capabilities and increase your profits by giving you the solution to printing designs on complex fabrics.
