Ans: Sublimation ink is very different from dye-based ink. The key difference lies in the way ink bonds with the fibers of the substrate fabric. Sublimation ink undergoes a transformation from solid to gas on application of heat and fuses with the fibers of polyester fabric. Meanwhile, dye-based ink merely sits on the fabric surface. Due to this difference, sublimation ink offers a more vibrant and durable print when compared to dye-based ink.
