Rotary Heat Press Machine-Work Conditions in Addition to Heat and Press

What are the conditions for the rotary heat press machine to work in addition to temperature and time?

The rotary heat press is an indispensable mechanical device in thermal transfer technology. If we want to perform thermal transfer, follow the steps below: first connect the computer to the printer, edit the picture of the pattern to be printed; then print it onto the sublimation paper through the sublimation printer; then, dry the pattern on the transfer paper; Finally, the hot press is used to press the pattern on the paper onto the final material, and the thermal transfer is completed.

The traditional sublimation transfer refers to printing, by printing a sublimation transfer ink onto a paper, by overlaying the printed paper with a fabric by a rotary printing machine, heating, pressurizing or decompressing the dye on the paper. The sublimation in the gas phase state is transferred to the fabric.

There are other printing technologies, such as screen printing, gravure printing, etc., printing the graphic on the thermal transfer paper or plastic film, and then heating and pressing through a wide-width hot press to transfer the image to On fabrics, leather and other items.

The thermal transfer film refers to a graphic with a tackifier. Under the combined action of the heat and pressure of the hot press, it can be separated from the carrier film together with the protective layer to firmly transfer the special function printing film which is followed by the surface of the substrate.

In addition to temperature and time, the pressure of the heat press machine is also a very important condition. If the pressure is too small, the gap between the fabric and the flower paper is large, and the yarn is round, so that the dye gas molecules collide with the air and escape, resulting in poor effect, and the dye is easy to seep, the lines are thick and the pattern is blurred.
