Sublimation transfer is also known as vapor phase thermal transfer, which uses dye-type inks with sublimation conditions to use lithography, screen printing, gravure printing and other methods to mirror images, landscapes, and text that need to be printed in mirror image. The printing method is printed on paper. Then put the paper printed with graphics on the substrate, and then heat (usually about 200 ° C) and pressurize the ink on the sublimation transfer paper to directly change from solid to gaseous state, so as to transfer the graphics to the substrate Thing. In this process, the paper used for transfer is called "sublimation transfer paper", and the sublimation transfer ink is mainly composed of a sublimable dye and a binder.
So how to choose a thermal transfer printer?
- The temperature of the machine iron must be average
The temperature of the hot plate determines the quality of the transfer. The temperature of each place on the hot plate must not differ too much, and it must be average and not small or large to ensure the quality of the hot stamping.
- Constant temperature of hot plate
Constant temperature is a place that most people often overlook. The constant temperature of hot stamping is very important for a large number of hot stamping. Having good constant temperature can ensure the quality of hot stamping from the first garment to the 100th garment, and even the 200th garment. The temperature of the hot plate is at the temperature you set, so that the quality of the hot stamping will not be discounted.
- Is the pressure of the machine even?
The more even the pressure, the tighter the pattern can be pressed against the cloth or other objects. Often, the pressure around the transfer machine will be uneven, concentrated only in the center, and the transfer will fail.
