Sublimation printing uses heat to convert solid dye directly into gas, which penetrates into polyester fibers or polymer coated substrates and bonds permanently into the material itself. The print becomes part of the substrate instead of sitting on top of it — no feel, no fade, no crack or peel.
Sublimation only works on two types of substrates: 100% polyester or high polyester blend fabrics, and rigid items with a polymer coating designed to accept sublimation dye (certain drinkware, mugs, metal panels, hard goods).
Sublimation does not work on cotton, natural fibers, dark colored polyester, or uncoated hard substrates. When a project calls for cotton apparel, dark garments, or multi fabric runs, DTF or screen printing is the right method. When a project calls for full color photo quality on white or light polyester, nothing else competes with sublimation.
