UV printers and hot stamping are two different devices and cannot be compared. The processes are different. The application of UV printers in the advertising industry can print album covers or other signs, hard and soft materials. Both can be printed, and the printout will have a concave and convex effect. Then hot stamping is simply to apply a layer of gold on the surface of the material. The function of the hot stamping machine is relatively simple, it can only be gold or silver, but UV printers can print many colors, too. The computer controls CMYK, but it cannot produce gold or silver.
