Heat transfer printing is a new printing process, which has been introduced from abroad for less than 10 years. The printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing (resolution up to 300 dpi), and the pattern is pre printed on the surface of the film. The printing pattern is rich in layers, colorful, changeable, small color difference and good reproducibility. It can meet the requirements of the designer, and is suitable for mass production of 5 / 5, 5 / 5 and 5 / 5
