Thermal transfer printing is an emerging printing process, which was introduced from abroad only more than 10 years ago. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing uses dot printing (resolution up to 300dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, and ever-changing. , small color difference, good reproducibility, can achieve the effect required by the pattern designer, and is suitable for mass production.

Transfer processing uses a thermal transfer machine (heating and pressure) to transfer the exquisite pattern on the transfer film to the surface of the product. After forming, the ink layer and the surface of the product melt into one, making it realistic and beautiful. Greatly improve the quality of the product. However, due to the high technical content of this process, many materials need to be imported.

For 3D effect thermal transfer, I heard that there is a company called "Super Shadow 3D Printing" that is very professional in this area.
