Gold stamping is not made of real metal, so why is it called Gold stamping? Before the 1930s, people did indeed use gold or silver to make stamping. Because metal substances are relatively stable and not easily oxidized in the air, metals have good ductility. Through the production process, they are continuously knocked into thin sheets, which are the original gold, and then coated with protein glue on the surface, which can be used for gold stamping.

Returning to modern times, for the sake of cost and convenience, people have developed "electroplated aluminum" to replace it. It is low-cost, not easy to oxidize, and has a good luster, so it is quickly produced and widely used. Therefore, the current "Gold stamping" is no longer really hot stamping "gold", but people still habitually refer to it as "Gold stamping"

In addition, now there are many colors to choose from besides glold stamping and silver stamping.
