The printers we use do not use a stick on vinyl to print your shirts, hoodies, and more. So you never get a shirt with a hard stiff design printed on it. No, they use a process called dye-sublimation. This means Dye-sublimation printing is a computer printing technique which uses heat to transfer dye onto materials such as a plastic, card, paper, or fabric. The sublimation name was first applied because the dye was considered to make the transition between the solid and gas states without going through a liquid stage.
Dye sublimation inks are a disperse dye suspended in a liquid solvent, like water. The images are initially printed on coated heat-resistant transfer paper as a reverse image of the final design, which is then transferred onto polyester fabric in a heat press operating at a temperature around 180 to 210 C (375 F).
This type of printing yields beautiful and permanent colors that are embedded in the substrate or fabric, rather than printed on the surface. Images on fabric won't fade or crack even after multiple washings.
