This process is a kind of thermal transfer technology and a new printing process. The printing mode of this process is divided into two parts: transfer film printing and transfer processing. The transfer film is printed by dot printing (resolution up to 300dpi), and the pattern is printed on the surface of the film in advance. The printed pattern is rich in layers, colorful, ever-changing, with small color difference and good reproducibility, which can meet the requirements of designers and is suitable for mass production.

Advantages of thermal transfer printing technology:
1, simple printing
It does not need the steps of plate-making, plate-making printing and repeated color matching, and does not need various types of tools and materials needed for screen printing and thermal transfer. To use a general printer, you only need to prepare an ordinary computer. The operator can print independently, saving manpower and material resources. The method is simple and desirable, and the experience of the operator is not high, as long as he knows simple picture processing software.
2, no damage
It can be printed not only on hard materials, such as crystal, stone, metal and glass, but also on soft materials, such as leather, cloth and cotton. It can be printed on inorganic matter or complex and changeable organic matter. More and better compatibility with materials, avoiding the problem of selecting materials for screen printing and water transfer printing, and avoiding the damage of thermal transfer printing to organic materials such as leather, cloth and cotton.
3, the location is accurate
It avoids the problem of position deviation encountered in manual printing, which is no longer a simple manual operation and process printing in the past. It is better combined with high-tech computer synthesis and automatic control technology, which can accurately align the area and position to be printed and avoid the position deviation problem encountered by manual printing. Because it is a one-time multi-color printing, there will be no problem of color registration.
These advantages can also be combined with engraving and etching very effectively, such as printing beautiful pictures in the engraved area or precise etching after printing. , in the carving industry can also have a good breakthrough.
4. Professional application
The universal printer can change the content and effect of printing at any time, and can print numbers one by one without complicated plate making. Many products have product codes on the metal nameplate behind them, and each group of codes corresponds to a product. For example, the badges and work permits of factory employees can also be printed according to one-to-one numbers, and the heads can also be added.
The manufacturing process is simple and the cost is low.
