Classification Of Thermal Transfer Technology

Apr 01, 2020

Thermal transfer technology can be divided into thermal forward transfer and thermal pressure transfer. Thermal forward transfer is also called gas phase thermal transfer, which is to choose dye-based ink with forward conditions, and use lithography, screen printing, gravure printing and other methods to mirror portraits, scenery, characters and other graphics that need to be printed. The reverse method is printed on the paper. Then put the paper with the printed text on the substrate, and heat (usually about 200 ℃) pressure method to make the ink on the forward transfer paper directly change from the solid state to the gaseous state, thus transferring the graphic to the substrate Physics. In this process, the paper used for transfer is called "forward transfer paper", and the forward transfer ink is mainly composed of the forward dye and the binder.

Thermal press transfer uses screen printing (also gravure printing, etc.) to print graphics on thermal transfer paper or plastic, and then transfer the graphics to the substrate by heating and pressing. However, with the widespread use of laser printers and inkjet printers, many small workshops choose laser printers to print graphics made with a computer directly on transfer paper, perhaps using inkjet printers to print graphics on ordinary printing paper. Then copy it to the transfer paper with an electrostatic copier. At the end, transfer the graphics on the transfer paper to the substrate by heating and pressing. This is the digital thermal transfer technology that we have widely mentioned today.
