What exactly is sublimation? In simple terms, it’s a method of printing that transfers a design into a material or fabric using ink and heat. In the world of apparel, it’s a game-changer in that it allows whole garment prints — designs that go seam-to-seam. So how does sublimation work? Well, sublimation printing uses heat to bring ink and fabric together as one nearly. First, a design is printed onto a particular paper. The inks used turn into gas when brought under heat, then combine with the fabric and permanently print onto the fabric. The effects are permanent and less prone to fading, as the ink is embedded in the material or substrate rather than simply laying on top like a regular print.
