The bronzing process is divided into hot bronzing process and cold bronzing process.

Hot stamping is a process in which metal foil is transferred to the surface of printed matter or other items by hot pressing to increase the decorative effect. Hot stamping is further divided into: ordinary flat hot stamping, three-dimensional hot stamping (commonly known as embossing and embossing hot stamping), and holographic positioning hot stamping.

Cold foil stamping is a process of transferring metal foil to the surface of prints or other items without heating, only through pressure and the force of adhesion and peeling.
