The dye sublimation process uses heat and pressure to turn solid dye into gas that bonds inside polyester or polymer-coated surfaces. You mirror a design, print it on sublimation paper, then press it at the temperature, time and pressure your blank, paper and ink makers specify. The result is a permanent, full-color print that will not crack, peel, or wash away.

Sublimation printing is a digital method that uses heat and pressure to turn solid dye into gas, which bonds with polyester fibers or polymer-coated surfaces. The image becomes part of the material, so it resists cracking and peeling. Press settings depend on the blank, paper and ink, so follow their makers' instructions; the method works on polyester apparel, coated mugs and metal panels, but not cotton.

DTF powder is selected by matching particle size to fabric: fine (80–120µm) for lightweight and detailed work, medium (120–160µm) for general apparel, coarse (160–200µm) for heavyweight fabrics like hoodies and canvas. This guide covers particle-size effects on adhesion, detail, hand feel, and durability, plus curing specs, common mistakes, and Alpha Print Supply's fine and premium powder options.
