Whether it is picture book or color page printing, it is indispensable to make a plate. The printing plate is made according to the requirements of the printed matter. The general printing plates are: ordinary hot stamping plate, three-dimensional hot stamping plate, bottom mold relief printing plate; the three hot stamping plates have different advantages and characteristics. The following introduction uses three-dimensional hot stamping The advantages of the printing plate; The use of chopsticks can be dated back to 6000 years ago, firstly by the Chinese, then it spread to other Asian countries including Japan and Korea. Today, they are widely used around the globe.For east Asian countries, chopsticks are as important as cutlery. However, we have Metal Chopsticks which are of good quality and popular.

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 version, because it needs to form a three-dimensional relief pattern, the hot stamping plate is generally concave, and has a deep and shallow level of change, depth It is also deeper than ordinary hot stamping plates and has higher precision. At present, the domestic copper photolithography corrosion method is mainly used. The advantage of this method is that the cost is relatively low and the process is relatively simple, but it is only suitable for flat bronzing. Due to the poor three-dimensional impression, the service life is relatively short, and the printing resistance is only about 100,000 prints, it is commonly used in printing plants. For packaging products that do not require high relief effect.
Nowadays, engraved brass plates are widely used abroad. Scanners are used to scan the patterns to be stamped, the data is stored in the computer, and then the three-dimensional engraving is controlled by the computer and software to form a female gravure with rich three-dimensional patterns. . Because it is controlled by a computer, it can form very fine patterns, and it is more ideal for the performance of fine parts. The printing resistance can reach more than 1 million prints, so it is very suitable for production of high quality and large printing volume. Three-dimensional bronzing female 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, three-dimensional bronzing is more suitable for some high-quality and long-term jobs that require anti-counterfeiting functions, such as cigarette packs, wine bags, health care product packaging, and greeting cards. Previously, this hot stamping plate had to be processed abroad, the cost was relatively high, the delivery was not timely, and the design effect was not satisfactory. At present, there are already a small number of domestic manufacturers that can process this hot stamping plate, which effectively reduces costs. In particular, the direct communication between the processing manufacturers and the designers of the printing plant can correctly understand the design intent and obtain satisfactory results.
