Film sublimation is used to print around the edges of phone cases. First step: your design is printed on film paper and the jigs are pre-heated for further processing.
Secondly, we start the transfer phase. Heat and pressure is used to melt the film around a phone case. Heat opens the outside material of the case and turns the sublimation inks into gas. That way your design can transfer onto the product.
This printing technique is mostly used for photo printing. We use phone cases with special materials to maximize ink absorption for a vivid, photo paper-like result.
