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

In the product bronzing process, the choice of bronzing paper plays an important role, so the following 6 aspects should be paid attention to when choosing bronzing paper:1. Understand the substrate of the product. The bronzing substrate determines the series of bronzing paper.

There are many methods of Relief Printing. It can be selenium from a photographic negative on a metal sheet and corroded to form a relief printing plate, or a photographic negative can be sun-dried on a photosensitive resin to form a relief printing plate; and an electronic engraving machine can be

Etching machines can be divided into chemical etching machines and electrolytic etching machines. In chemical etching, a chemical solution is used to achieve the purpose of etching through a chemical reaction. A chemical etching machine is a technology that removes materials by chemical reaction or

Relief Printing, printing using letterpress (printing plate with raised parts of graphics and text). Referred to as embossing. It is one of the main printing processes. The longest history, continuous improvement in the long-term development process.

The hot stamping process uses the principle of hot-press transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for hot stamping is anodized aluminum foil, the hot stamping is also called anodize

The pretreatment processes for metal corrosion mainly include: photosensitive etching, screen printing, and stickers. Each process has its own advantages and disadvantages.
