Method of marking light-coloured polyester materials. This method is most often used for prints on sportswear: T-shirts, tops, sweatshirts and also accessories and gadgets such as cushions, mugs, bottles. Due to the fact that it is a chemical process, sublimation permanently penetrates the structure of the material, thanks to which the print is resistant to repeated washing and is not felt by touch. It perfectly reproduces multicoloured photos and graphics.
