Heat transfer printing is a new printing process, which has been introduced into China for more than 10 years. The process printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing (with a resolution of 300 dpi) to pre print the pattern on the surface of the film. The printed pattern is rich in layers, bright in color, diversified, with small color difference and good reproducibility, which can achieve the effect required by the designer and is suitable for mass production. The transfer processing is carried out by hot transfer The printing machine processes (heating and pressing) the exquisite patterns on the transfer film on the product surface. After forming, the ink layer and the product surface are integrated, lifelike and beautiful, greatly improving the product grade. However, due to the high technological content of this process, many materials need to be imported.
