Why is bronzing called bronzing?

As early as the 1930s, people did use gold or silver to make hot stamping. Because its chemical properties are stable and it is not easy to oxidize in the air, use their good ductility to make it into a very thin metal foil by knocking and rolling, and then coat shellac (dry glue) or protein glue on one side , And then used for hot stamping.

The gold foil in the modern hot stamping process has been replaced by "anodized aluminum". Due to the low cost of anodized aluminum and its good metallic luster, anodized aluminum hot stamping has developed rapidly and is widely used, but it is still called "electrochemical aluminum". Bronzing".

"Aluminum" is a silver-white metal. Generally, it can only be imitation silver foil hot stamping. If you want to show golden yellow like gold foil, you only need to coat a layer of golden dye. In addition, dyes of various colors such as red, green, and blue can be added to make anodized aluminum a variety of colors.

The modern hot stamping method can make the surface of the printed product have multiple colors of metallic patterns at the same time, and it can also combine different hot stamping effects. In addition to the surface decoration function, hot stamping also has another important function that is anti-counterfeiting. Now we can see that many documents or certificates use hot stamping and holographic hot stamping as anti-counterfeiting methods. Many packaging boxes that require anti-counterfeiting use holographic patterns for anti-counterfeiting, in addition to using gold foil for surface finishing.

The unique metallic luster and strong visual effects of bronzing can make the decorated products look unique. Many people use bronzing to make slight changes on the business cards. If used properly, they can show a beautiful and unique sense. If the area is too large Bronzing, poor design, it is easy to look tacky. Large numbers are not necessarily beautiful, so be careful in design.
