Nowadays, the traceability of counterfeiting and anti-counterfeiting is everywhere, which has become the most troublesome problem for government supervision departments: some companies start from selling codes, mainly to allow food companies to buy the labels they produce, and let consumers scan the two-dimensional labels on the labels. The query information can be displayed at the time of the code, and the content displayed in the QR code is for the client company to fill out by itself, and is not associated with any relevant department form, so it seems that a lot of money has been spent to build the system. Finally, it is found that the scanned data is either Fake, or the data is incomplete! Strictly speaking, this kind of pseudo-traceability system that only realizes terminal query convenience cannot be called traceability; such a pseudo-supervision platform not only hates the regulatory authorities, but consumers hate it even more. Seeing the traceability label should have been relieved. Who knows that the traceability information in it is actually fake, which is why the assembly line coding equipment is needed, because it directly prints the anti-counterfeit traceability QR code on the product packaging. Compared with laser printing, it will burn and damage the packaging. The equipment is more suitable for anti-counterfeiting traceability QR code printing, which can realize online/offline high-speed printing. The UV inkjet printer is closely connected to the production line. The logo printed by it usually has the characteristics of high adhesion and wear resistance, which can ensure the long-term availability of the QR code/barcode information in the product circulation process. When products circulate in the market, consumers can scan the QR code/barcode through their mobile phones to learn the traceability information of the product, and retailers can also view traceability information through the terminal scanner. The assembly line coding equipment has the characteristics of high precision and fast efficiency. UV inkjet printers can print a wide range of materials. After UV curing, the identification information such as QR codes and barcodes are firmly attached, water-resistant and scratch-resistant, and the reading level is also better. Ensure that, especially when printing images on flexible substrates such as plastic films, its adhesion and toughness are more significant. It can meet the needs of enterprises to realize packaging codes even at high speeds, and can be seamlessly integrated into existing production lines to ensure existing production efficiency.
