Sublimation is a process whereby an inkjet printed image on special paper is transferred to a polyester coated material when heat (200°C) and pressure are applied. The inks transfer and bond to the coating on the material giving a smooth and durable finish. Other heat transfer methods only apply colour to the surface of the substrate resulting in a finish that can be easily scratched or damaged. For instance, a colour photograph can be sublimed to a metal plate. Sublimation produces stunning and vibrant colours.
