The production of bronzing plate mainly adopts photographic corrosion technology and electronic engraving technology, and the material is mostly copper plate or zinc plate.

The material of the copper plate is delicate, and the surface finish and heat transfer effect are better than those of the zinc plate. The use of high-quality copper plate can improve the gloss and outline clarity of the hot stamping graphics. The traditional photographic corrosion technology has the advantages of simple process, low cost and short service life. It is mainly used for bronzing of text, thick lines and general images.

The hot stamping plate produced by electro-engraving can express rich and delicate layer changes, and its printing resistance is high, which is suitable for the packaging of cigarette packs, products with fine product quality requirements and large batches.
