What is Dye Sublimation?
Most polyester fabrics, such as many of the popular “Performance Garments”, are dyed using a sublimation process. The dye of these fabric will migrate into the graphic after heat press. Many sporswear are made of polyester fabric.
Dye Migration Can Discolor Heat Transfer Appliques
When you heat press heat transfer vinyls onto a sublimated garment, the high heat will lead to dyes of the polyester migrate and discolor an applique.
