The basic principle of black hot stamping paper is to heat and pressurize gold foil from one carrier to another. Generally speaking, you need to use a bronzing machine to complete this operation, and then use the template for thermal transfer. The stamping task can be completed by loading the template on the stamping machine by means of high temperature glue, adjusting the temperature and pressure to an appropriate level, and covering the stamping paper on the ironed object. Generally speaking, the bronzing process is very simple.
