The three-dimensional bronzing technology is very different from ordinary bronzing. In addition to the relief-shaped three-dimensional pattern, it is different in plate making, temperature control and pressure control. 1. Plate making 1. Ordinary hot stamping plate High-quality hot stamping plates are the guarantee of the quality of hot stamping. The production of ordinary hot stamping plates is relatively simple, mainly using photo-etching plate-making process and electronic engraving plate-making process. The commonly used plate material is copper plate or zinc plate. Copperplate is the mainstream hot stamping plate because of its fine texture, smooth surface, good heat transfer performance, wear resistance and pressure resistance, and is not easy to deform. The use of high-quality copperplate can improve the gloss and clarity of hot stamping graphics. Zinc plates can also be used for hot stamping of some packaging printing products with a small number of hot stamping and low quality requirements. Photo-etching plate making is a traditional manufacturing method with simple process, low cost and low precision. It is mainly suitable for text, thick lines and images with low quality requirements. The hot stamping plate made by electronic engraving can express the image layer richly and finely, and can reproduce fine lines and graphics with uneven thickness, but the relative cost is relatively high. 2. Three-dimensional hot stamping plate The production principle of the three-dimensional hot stamping plate is the same as that of the ordinary hot stamping plate, but it is more complicated than the ordinary hot stamping plate, because it needs to form a three-dimensional relief pattern. The printing plate is deeper and the precision is higher. At present, the domestic copper photolithography corrosion method is mainly used. This method has the advantages of low cost and simple process, but it is only suitable for flat bronzing. Due to poor three-dimensional feel, short service life, and printing resistance of only about 100,000 prints, it is commonly used in some packaging that does not require high relief effects Product. At present, engraved brass plates have been widely used abroad. Scanners are used to scan the patterns to be stamped first, the data is stored in the computer, and then three-dimensional engraving is carried out under the control of the computer and software to form a female gravure with rich three-dimensional patterns. Because it is controlled by a computer, it can form a very fine pattern, which is more ideal for the performance of fine parts, and the printing resistance can reach more than 1 million prints, so it is very suitable for the production of high-quality, large-volume three-dimensional bronzing Yin Die gravure. Of course, due to the need to be equipped with high-end electronic engraving machines, scanners, computers and software, engineering and technical personnel, etc., its production cost is higher than the photo etching method. It is precisely because of its complicated production and technical difficulty that it can better prevent counterfeiting by some illegal manufacturers and has certain anti-counterfeiting functions. Therefore, for some high-quality and long-term work that requires anti-counterfeiting functions, such as cigarette packs, wine bags, health care product packaging and greeting cards, it is very suitable for three-dimensional bronzing. Previously, this hot stamping plate had to be processed abroad, the cost was high, the delivery was not timely, and the design effect was difficult to satisfy. At present, there are a small number of domestic manufacturers that can process this hot stamping plate, which effectively reduces the cost. In particular, the processing manufacturers and designers directly communicate, and can correctly understand the design intent, so as to obtain satisfactory results. Second, the bottom mold relief Three-dimensional bronzing is different from ordinary bronzing. The base of ordinary bronzing is flat and does not require special production. The base of three-dimensional bronzing must be a male relief corresponding to the hot stamping plate, that is, the concave part of the hot stamping plate should be on the base plate. It is raised, and the height of the protrusion corresponds to the depth of the hot stamping plate. The method of making the bottom mold relief is the same as that of the concave-convex embossed positive mold relief, and the commonly used materials are gypsum and glass fiber. If you use gypsum, you must complete the production on the machine, so the process is more complicated, and it is troublesome to replace the bottom plate, but the cost is lower, and it is more commonly used in China. If glass fiber is used, it can be pre-made according to the model of the hot stamping plate, and the positioning hole is made in conjunction with the processed copper plate to facilitate replacement of positioning. The bottom relief is to cooperate with the hot stamping intaglio to form a three-dimensional relief pattern, which must exactly correspond to the hot stamping plate. However, three-dimensional bronzing is different from concave and convex stamping. Most of the concave and convex stamping does not require heating, and three-dimensional bronzing must be heated at high temperature. During hot stamping, as the temperature rises, the hot stamping plate will expand, but the temperature of the bottom mold relief will remain basically unchanged, which will cause the hot stamping plate and the bottom mold relief to not match, resulting in crushing the bottom mold Or the phenomenon that can not be hot stamped. Therefore, when making the bottom mold relief, the expansion rate of the hot stamping plate must be fully considered to produce an accurate bottom mold relief.
