[0002] Hot stamping is also called transfer printing, which is a process of transferring the pattern on the electroplated aluminum to the substrate through the action of heat and pressure. The substrates for hot stamping are generally paper, cardboard, fabrics, coatings, metal sheets, etc. The working principle of hot stamping equipment is: when the hot stamping plate is heated to a certain degree along with the attached electric heating base plate, it is pressed with the substrate through the electroplated aluminum film, and the glue layer, metal aluminum layer and color layer attached to the polyester film of the electroplated aluminum are transferred to the substrate by the action of temperature and pressure.
