Sublimation Technology, What is it?

Sublimation technology is a printing method where special solid inks are transformed directly into gas using high heat, allowing the ink to permanently bond with polyester fibers or polymer-coated surfaces. Unlike traditional printing methods that place ink on top of the material, sublimation makes the design become part of the fabric itself, resulting in vibrant colors, smooth texture, and prints that never crack, peel, or fade. The process works by printing the artwork onto sublimation paper with sublimation ink, then applying heat and pressure—usually around 180–200°C—causing the ink to vaporize and penetrate the material. Once it cools, the gas turns back into solid form inside the fibers, locking the design permanently. This makes sublimation ideal for high-quality apparel, sportswear, mugs, tumblers, phone cases, home décor items, and all-over prints, as long as the surface is polyester or polymer-treated. However, it doesn’t work on cotton or dark fabrics because the ink is translucent and requires a white polyester base to appear vivid.
