What is Sublimation shirt printing?
Sublimation shirt printing is a specific process of printing that first involves printing onto a special sheet of paper, then transferring that image onto another material (usually polyester or a polyester mix).
The ink is then heated until it disintegrates into the fabric.
The process of Sublimation shirt printing costs more than other methods, but it lasts longer, and will not crack or peel over time, like other shirt printing methods.
