Sublimation is the process of printing designs on fabric. The process involves the use of heat and pressure to imprint dye on your fabric of choice. One difference between sublimation and screen printing is that the former infuses the dye into the fabric, while the latter lays the print on top of the fabric. As a result, bulk sublimation t-shirts produce better and longer-lasting quality. During the process of sublimation, the ink changes from its solid state to a gas without liquifying, enabling the ink to penetrate and settle on the fibres of the fabric.
The end product is detailed imprints that are visible but that you can’t feel when you run your palm across the print. With sublimation, there’s no concern for prints peeling, wearing, or washing out, unlike with screen printing.
