Screen Printing Hot Stamping Process Gorgeous and beautiful, bright color aluminum, through the hot stamping machine, displayed on the substrate, its beautiful color has won wide appreciation. With the development of the printing industry, the printed matter nowadays is focused on the printing of gold patterns on the surface of prints. Such as: book covers, book cover, invitations, business cards, couplets and so on. According to years of experience, a simple, low-cost method of bronzing is the screen printing bronzing method. This hot stamping method can be compared with the past zinc and copper plated hot stamping methods. Zinc and copper plate hot stamping method is more expensive than screen printing hot stamping method, and the system hot stamping plate has a long cycle time. Screen printing hot stamping plate hot stamping plate making has a short time and low cost. No matter how complicated the pattern is, as long as the computer outputs the hot stamping plate. Film can be plated hot stamping. The hot stamping method can be hot stamped in metal, bamboo, paper, glass, cloth, plastic, leather, stone, etc. Process flow: pattern negative film → screen printing plate → hot stamping paste → hot stamping → finished product 1. Pattern negative film production. Use a computer to eject the desired pattern and text and use a laser printer output. 2. Stencil version. Use 100-200 mesh polyester screen and water-oil photosensitive plastic plate, according to different hot stamping materials, choose different hot stamping adhesive. The hot stamping glue has water-based and oily points, and the water-based hot stamping glue is suitable for hot stamping of paper and cloth materials. Oily hot stamping adhesive is suitable for non-paper and cloth hot stamping. In order to make the stamping firm, non-paper, cloth material hot stamping must use oily hot stamping glue. Therefore, when the screen version of the election of water and oil sexy light plastic plate. Whether it is paper, cloth material, non-paper, cloth material can use water oil sexy light plastic version, printing hot stamping glue. 3. Printing hot stamping glue, according to different hot stamping materials, choose different hot stamping glues, after selecting the hot stamping glue, the printing pattern needs hot stamping pattern to be dry stamping. The pattern is clear when printing. 4. Hot stamping. Put the required size of anodized aluminum on the hot stamping material, and then hot stamping. Note that the temperature is controlled at 60°C during hot stamping. Hot stamping equipment used hot stamping machine or iron and other hot stamping. After a few seconds of hot stamping, the cold aluminum foil was slowly torn off after the cold stamping of the material. The pattern was dazzling. Through the screen printing gilding method can be produced bronzing crafts, couplets, calligraphy, art mirror and so on. Problems in the hot stamping process In China, anodized hot stamping has become an indispensable method of surface decoration for modern packaging. However, in addition to having a pleasing, eye-catching, or eye-catching effect, packaging cartons must also convey certain product information. In order to facilitate the display of modeling, it is necessary to have the function of protecting the goods. To achieve the above purpose, the birth of a packaging carton must be printed, stamped, glazing (UV glazing, water-based glazing, ink glazing, etc.), laminating (precoating film dry coating, ie, coating Wet coating, counter-boring, die-cutting indentation, folding gluing, and multiple processing steps. Faced with such a complicated processing process and so many choices, how to apply the hot stamping process reasonably to complement each other's various processing technologies is a profound knowledge, and it requires process designers to gradually explore each process operator. Collaborative solution. However, the hot stamping of aluminum foil is a relatively complicated processing technology and is influenced and restricted by materials, equipment, and process conditions. Therefore, at present, the overall level of hot stamping in our country is not too high and there are many problems. Here we summarize some issues that need attention in hot stamping. 1. Reasonable selection of anodized aluminum The choice of anodized aluminum must be matched with the hot stamping substrate. For example, the commonly used electroplated aluminum Venus No. 400 imported from the United States is not suitable for hot stamping on the ink layer, while the type 338 electro-aluminum imported from Germany and the type 88 electro-aluminum produced by Shanghai Hot Stamping Material Factory of China are both There is a good combination of fastness with the printing ink layer, and other domestic brands of aluminum also have models suitable for hot stamping on the ink layer. In addition to considering the color and price of galvanized aluminum, the user selects the galvanized aluminum, and the hot stamping of the substrate and its surface state (whether on the printing ink layer, the glazing surface or the surface of the coating film) must be addressed to the supplier. Explained. 2. Determination of hot stamping process conditions Moderate hot stamping pressure, hot stamping temperature and hot stamping time are three prerequisites for good stamping quality. Hot stamping temperature and hot stamping time can be coordinated within a certain range. For example, when the hot stamping temperature is slightly lower, it can be compensated by reducing the stamping time. When the hot stamping temperature is slightly higher, it can be matched by reducing the stamping time. At present, neither the materials used in hot stamping in China nor the hot stamping process are standardized. As there are no provisions in this area, there are many printing companies that are very random when processing. The strict management of the printing plant will, after a period of practice, find out a set of suitable process conditions for the factory: experienced stamping workers who pay attention to the accumulation can even pass water by hand even without a temperature indicator. Quickly touch the plate to determine if the stamping temperature is appropriate. The adjustment of hot stamping pressure should be flexibly controlled according to the layout. Large areas of hot stamping require greater pressure, while fine text and lines require less pressure. When the same layout has both a large area of ​​hot stamping and a small text to be stamped, it is possible to perform partial pressure compensation by pad printing in order to balance both. If layout factors are not taken into consideration, the entire plate is stamped with the same pressure, which will inevitably result in a large area of ​​hot stamping with fine text stencils, or fine text stamping with clear and large areas of hot stamping.
