Heat transfer film hot stamping pressure, speed and temperature

Heat transfer film hot stamping pressure, speed and temperature

1 Heat transfer film hot stamping factors
During the hot transfer hot stamping process, the hot transfer film hot stamping pressure, hot stamping speed and hot stamping temperature are mutually restricted, and its process parameters are always determined in the order of hot stamping speed, pressure and temperature.

2 Hot transfer film hot stamping speed
First determine the hot transfer film hot stamping speed. Generally, it is treated as a constant and not easily changed. Then find the hot stamping pressure and hot stamping temperature that are suitable for it. This can simplify the operation procedure and easily control the hot stamping quality of the hot transfer film.

In addition, during the hot stamping process of the hot transfer film, it is also necessary to consider whether the substrate, hot stamping plate, hot stamping machine hot transfer machine fixture and pad are suitable.

Finally, the environmental conditions should be studied, including indoor temperature and humidity, substrate temperature, indoor air cleanliness (dust content), etc.

3 Hot transfer film hot stamping pressure
Generally speaking, the hot transfer film hot stamping pressure, the pressure applied by the hot transfer rubber roller to the surface of the hot transfer printing film and the hot transfer carrier, should be moderate.

So, how to control this moderate hot transfer film hot stamping pressure? !

First of all, if the ink falls off locally or the transfer surface is not smooth after hot stamping, it can generally be judged that the pressure of the hot roller is not enough; on the contrary, if the ink on the transfer surface is open or the base film is difficult to fall off after transfer, it can be judged that the pressure is too high.

All of these are the most basic criteria for judging whether the pressure is appropriate.

4 Hot stamping temperature of hot transfer film

The hot stamping temperature of hot transfer film has a significant impact on the hot stamping effect. If the hot stamping temperature of hot transfer film is too high, it is easy to damage the substrate, and if the hot stamping temperature is too low, it may not achieve normal transfer. The hot stamping temperature of hot transfer film should be determined according to factors such as substrate, flower film, and hot transfer machine. Different materials have different hot stamping temperatures.
