What is sublimation heat transfer printing process?

Heat transfer printing is an emerging printing process that has been introduced from abroad for only over 10 years. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing uses dot printing (with a resolution of up to 300dpi) to preprint patterns on the surface of the film. The printed patterns are rich in layers, bright in color, ever-changing, with small color differences and good reproducibility, which can meet the requirements of the pattern designer and are suitable for mass production.

The transfer printing process uses a heat transfer machine to process (heat and pressure) the exquisite patterns on the transfer film and transfer them onto the surface of the product. After forming, the ink layer dissolves into the product surface, creating a realistic and beautiful appearance, greatly improving the quality of the product. However, due to the high technological content of this process, many materials need to be imported.

Sublimation tumbler is also called heat transfer baking cup, heat transfer mug, coating cup, etc. It is a personalized cup made from the external picture of the cup through heat transfer printing technology.
