Bronzing process in the hottest label printing

In recent years, with the development of commodity economy and the influx of foreign capital and technology, the domestic printing and packaging industry has been greatly developed. In particular, cigarette bag printing and label printing can be described as the most prominent embodiment of the use of advanced technology in the printing industry. In these two kinds of printing products, machines, consumables and technology have developed to the point that foreign counterparts are amazed

how to expand the measurement range of the most advanced technology and C) with the original licensed products; Technology is introduced into our daily production, and these technologies and processes are applied and localized, making them available as tools in the development of new products in production, which is a topic worthy of discussion by colleagues in the printing industry. Now, in the report on bronzing process and label, erdenebulgan Oyun, Deputy Minister of mining of Mongolia, is quoted to talk about the combination. If there is anything inappropriate, readers will not hesitate to correct

first of all, the bronzing process is divided into cold perm and hot perm. The principle of cold pressing is mainly to use pressure and special glue to combine the anodized aluminum with the substrate. The whole process does not need heating, bronzing plate and pad technology. At the same time, the narrow rotating machine is relatively expensive and complex to operate, which is economical and convenient. Its maximum hot stamping speed can reach 120 meters per minute. However, the cold ironing process started late, and due to the large consumption of anodized aluminum in the hot stamping process, the gloss of anodized aluminum after ironing is not as good as hot ironing, and the concave ironing effect cannot be achieved. Although the probability of electromechanical appearance is not very high, it has not yet formed a large-scale application in China. Judging from the future development trend, this is a technology with great potential and worth developing

the principle of scalding is familiar to everyone. In short, there are three material elements: machine, electrochemical aluminum, and bronzing plate. The three elements of technology are: temperature, pressure and speed. Bronzing method from round pressing, round pressing to flat pressing. Speaking of machines, people familiar with this process know that stora, which belongs to the Swiss boster group, is recognized as the king of bronzing in the world; In terms of electrochemical aluminum, Kurtz company is undoubtedly the leader in the bronzing industry; When a printing company has a first-class bronzing machine and electrochemical aluminum, the bronzing plate is very important. German h+m company belongs to Kurtz group, and its bronzing plate can make the perfect combination of machine and electrochemical aluminum. Therefore, there is often a joke in the bronzing industry: "when a Bronzer has these three things, no matter how bad it is, he can't complain.". Of course, the pad technology is also very important in the hot Ding art, and to master this technology can only depend on experience. Therefore, in a complete sense, in addition to having first-class machines and consumables, technicians' experience, that is, human experience, plays a decisive role in scalding

secondly, the stamping process has made great progress in label application in recent years. In particular, laser and holographic electrochemical aluminum, through the transfer effect of scalding, make the label products colorful and difficult to imitate. In view of the particularity of label anti-counterfeiting, anodized aluminum usually adopts a thinner PET film and glue layer to facilitate transfer, so as to achieve the purpose of mass and high-speed production. Compared with cigarette package printing process, label printing has less trouble of combining anodized aluminum with varnish and ink, so the production efficiency is higher than the former. In addition, there is another topic that cannot be ignored. The bronzing version of the big data platform needs to be managed. When pressing and ironing laser and holographic anodized aluminum, in addition to the clean and smooth surface, mirror polishing is also carried out to prevent the anodized aluminum from being Matt and distorted after transfer. Thus, the label products are bright and clean, which plays a role in protecting the brand and improving the product grade

with the development of cold pressing technology, more and more label printing manufacturers, as the development of technology and the expansion of application fields, as well as peers in the industry, have added their efforts

finally, from the perspective of the development trend of the printing industry, more and more new processes and technologies are combined with labels, such as flexo printing, silk screen printing, etc. through various methods to make labels bright and beautiful, which only improves the grade of products and increases the difficulty of anti-counterfeiting. As the saying goes, a hundred flowers bloom and a hundred schools of thought contend, making label printing more and more perfect
