The bronzing process is a special printing process that does not use ink. The so-called hot stamping refers to the process of hot stamping anodized aluminum foil onto the surface of the substrate under a certain temperature and pressure. In recent years, my country's light industry, packaging, and printing industries have developed rapidly, and commodity packaging and decoration have become an important means to promote commodity circulation. Every area of daily life from tobacco, alcohol, medicine, food to clothing, cosmetics, etc. has all reflected the rapid development of packaging and decoration printing, which has led to increasingly fierce competition in the printing market.
In order to improve the added value and technological content of printed matter, post-press finishing has attracted more and more attention. Nowadays, despite the continuous innovation of the post-press finishing process due to the development of science and technology, a variety of new processes such as cold hot stamping and holographic positioning hot stamping have appeared, but traditional hot stamping (also known as hot stamping) is an important process in post-press finishing. It plays a unique decorative role in printed matter and has not been left out. On the contrary, it still attracts people's attention and preference. Therefore, it is necessary to continue to discuss the bronzing process. The so-called hot stamping refers to the process of hot stamping the electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure.
The images and texts stamped on the anodized aluminum show a strong metallic luster, bright and eye-catching, and never fade. Especially gold and silver anodized aluminum, with its magnificent, exquisite, and elegant decoration, embellishes the surface of the printed matter, enhances the artistic quality of the printed matter, and plays a publicity effect that highlights the theme; its brightness greatly exceeds that of printed gold and printed silver, making the product It has a high-end feeling and beautiful enjoyment. At the same time, due to the excellent physical and chemical properties of anodized aluminum, it can protect the printed products, so the hot stamping process is widely used in high-end and exquisite packaging and decoration trademarks, wall calendars, book covers, and other printed materials; secondly, anodized aluminum hot stamping The range is very wide, from general book covers, trademark patterns, publicity advertisements, plastic products to daily necessities, from paper to leather, cotton cloth, etc.; furthermore, bronzing is a dry processing method, and the workpiece can be packaged and transported immediately after bronzing. Therefore, hot stamping technology is currently widely used, and the scope of application of hot stamping is still expanding.
Since the quality of electrochemical aluminum foil, specifications, models, etc. will affect the quality of hot stamping, the scientific and reasonable selection of electrochemical aluminum foil is a prerequisite for improving the quality of the hot stamping process.
