The stamping paper process is to transfer the aluminum layer in the anodized aluminum to the substrate surface by using the principle of hot press transfer to form a special metal effect. Because the main material used for stamping is anodized aluminum foil, so stamping is also called anodized stamping.
Electrochemical aluminum foil is usually composed of multi-layer materials, the base material is usually PE, followed by separation coating, color coating, metal coating (aluminizing) and glue coating. In the printing industry, it is commonly used to iron the electrochemical aluminum foil on paper, which is called bronzing. Bronzing is a general term of technology.
Gilding doesn't mean gilding. There are many kinds of bronzing paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.
