1. The hot stamping plate is the primary factor to ensure the quality of hot stamping
At present, the production of hot stamping plates mainly uses photographic etching technology and electronic engraving technology, and the materials are commonly used copper plates or zinc plates. The copper plate is made of fine material, and its surface smoothness and heat transfer effect are better than that of the zinc plate. Using high-quality copper plate can improve the gloss and outline clarity of the hot stamping graphics. The traditional photoetching technology is simple and low-cost to produce hot stamping plates. It is mainly used for text, thick lines, and general images. For finer foil stamping plates with uneven thickness of graphics and text, it is necessary to use secondary etching or electric engraving technology. Electric engraving to produce hot stamping plates can express rich and delicate layer changes, which greatly expands packaging expressive capabilities. This process is beneficial to environmental protection, but the investment in electric engraving equipment is relatively large, and the current engraving depth is not ideal enough, which can easily cause hot stamping

. The production technology of holographic anti-counterfeiting hot stamping plates is relatively high. In the past, they were mainly produced in Taiwan or abroad. The plate making cycle was long and they were only used for the packaging of fixed and large-volume products. At present, there are several domestic units that can produce it in Yuncheng, Shanxi, Beijing and Shanghai.

The selection of hot stamping equipment is a key factor in determining the quality of hot stamping. There are three types of sheet-fed foil stamping machines: flat-flattening, round-flattening, and round-pinching. Currently, the flat-flattening machine is the most widely used, mainly by Shanghai Yahua Printing Machinery Co., Ltd.

sheets per hour, which is currently the fastest single sheet hot stamping speed in the world. The fastest device. The three embossing methods of round press, round press and flat press, each have their own advantages and disadvantages. Round press and round press hot stamping are implemented using linear pressure. The total pressure is small, and large-scale printing can be easily completed with relatively small pressure. The area is solidly stamped, the movement is smooth, and the round-pressed round type has high production efficiency, which is especially suitable for large-volume hot stamping. However, because the arc surface of the copper plate is more difficult to process, the production cost is higher, and the heating roller is also more difficult to heat than the flat surface. The flattening operation is flexible and convenient, and is more suitable for short-run products. Compared with imported hot stamping equipment, domestic hot stamping equipment has obvious advantages in performance and price. The price of domestic hot stamping equipment is only equivalent to the price of similar foreign products

, but The registration accuracy, stability and function of the imported machine are significantly better than that of the domestic machine. It is also more durable than the domestic machine and is more suitable for the processing of fixed batches of high-end packaging products. Therefore, product type and batch size are the keys to determining the selection of hot stamping equipment. Whether you have

3. Hot stamping suitability
The so-called hot stamping suitability refers to the matching between the model selection of anodized aluminum and hot stamping speed, temperature, pressure and other factors. When equipment and other hardware are fixed, correctly grasping the hot stamping suitability is the most important means to improve the quality of hot stamping. The following is an analysis of some quality issues reflected in actual operations, in order to scientifically grasp the hot stamping suitability.

Failed hot stamping or inaccurate hot stamping is related to various factors such as surface characteristics of printed parts, properties of anodized aluminum, hot stamping temperature and pressure.
Powder spraying on the surface of the print
Too much or the surface contains additives such as adhesive remover and gloss paste, which will hinder the adsorption of anodized aluminum and paper. The solution is to remove powder from the surface or solve it in the printing process. Improper selection of anodized aluminum directly affects the hot stamping fastness. What type of anodized aluminum should be selected based on the size of the hot stamping area and the characteristics of the hot stamping material.
In short, there are many factors that affect the quality of hot stamping. Making high-quality hot stamping plates and correctly grasping the hot stamping suitability are the keys to improving the quality of hot stamping
