Heat transfer printing is a new printing process that has been imported from abroad for more than 10 years. The process of printing way printing and transfer printing film processing divides into two parts, printing using network printing, printing film pattern will be printed on thin film surface in advance, printing the design level of rich, colourful, go, small chromatism, good reproducibility, can meet the requirements of design patterns is effect, and is suitable for mass production; Stamping processing through the thermal transfer machine (pressurized heating) in one time will be fine pattern on the printing film transfer printing on the product surface, the surface layer and the printing ink after molding product dissolve into an organic whole, lifelike beautiful, greatly enhance the grade of the product.
