Thermal transfer technology is to print the pattern on thermal transfer paper, and then transfer the pattern to the substrate by applying certain temperature and pressure. In this process, thermal transfer paper plays the role of transfer carrier. According to the principle, thermal transfer paper can usually be divided into two types: hot melt adhesive type and thermal sublimation type.

Hot melt adhesive thermal transfer paper has a hot melt adhesive coating on its surface. This kind of thermal transfer paper is usually only used for cotton, silk, hemp and other substrates.

Thermal sublimation heat transfer paper is a pattern pre-made by computer, printed on paper with special ink by inkjet printer, and then overlapped with the substrate. At a certain temperature and pressure, the ink on the paper sublimates into gas phase and is transferred to the substrate to form a continuous and complete pattern.

Precautions:

1. pressure: if the pressure is not enough or too high, adjust the pressure adjustment knob at the back of the machine and increase the pressure clockwise; On the contrary, reduce the pressure;

2. Time: When the hot stamping time is up, the buzzer doesn't ring or keeps ringing. If it is uncomfortable, it must be transferred to the appropriate position;

3. Temperature: When the adjusted temperature is reached, the pointer of the thermostat is at the position of "180℃" (about 5 minutes). If the thermometer starts to rise and the heating plate does not generate heat, check the circuit.

4. When the handle is pressed down to the bottom, release the hand, and the handle will automatically lift and adjust the adjusting knob downward.

5. After hot stamping, raise your hand. When you feel tired, you can adjust the adjusting knob downward.
