The heat transfer printing process can divide into two parts: printing on film and transfer to products.
Printing on film technique includes mold heat transfer (suitable for large quantities) and digital heat transfer (suitable for small quantities).
- The heat transfer printing process includes two parts: printing on film and transfer to products.
- Printing on film process is printing pattern (logo, texts or images) on the surface of the film in advance. The printed pattern has rich colors, small color difference, also can meet the requirements of the designer, and it is suitable for mass production.
- Transfer to products process is transferring the pattern on film to the surface of the product through a heat transfer machine (heat and pressure). And the ink layer is integrated with the surface of the product after forming. The pattern looks vivid and beautiful, greatly improves the quality of the product.

- Printing on film technique is divided into mold heat transfer (suitable for large quantities) and digital heat transfer (suitable for small quantities).
- The main difference is that mold heat transfer needs creating dot-type electro mold; then install the mold into machine, then print logo or text into PET film. So the production spend is quick, and it is more economic for large quantities;
- While digital heat transfer do not need mold, can print the pattern on transfer paper by a special printer directly. But the production speed is slow, so it is suitable for small quantities.

Heat transfer technique is an emerging printing process which has only developed for about 10 years.
