The inkjet printer is a high-tech product that uses charged ink particles and is deflected by a high-voltage electric field to print patterns, text and numbers on the surface of various objects. The establishment of a two-dimensional code system can play a role in purifying the market. As information is more open and transparent, the living space of some low-cost and low-quality products will become smaller and smaller. In addition, it can further regulate the industry market and promote the healthy development of various industries. The two-dimensional code inkjet printer for commodity packaging supplied and sold can print production date, batch number, barcode, two-dimensional code, trademark patterns, anti-counterfeiting marks and Chinese characters. It is a powerful equipment for implementing the hygiene law and promoting packaging modernization. The QR code will play a very important role in standardization. With the continuous improvement of technical means, the use of product packaging QR code inkjet printers to resist counterfeiting is increasingly being applied to enterprises, that is, the trademarks of the same products. In different regions, under the premise of keeping other signs unchanged, through text marking, that is, different words are printed on the outer packaging of each product. The focus is on the variable QR code marking and the use of UV inkjet printers. In order to prevent merchants from destroying patterns and letters, invisible ink can be used to replace ordinary ink for printing. At present, UV coding equipment is increasingly used in various enterprises to give product coding. At the critical moment when packaging companies use product packaging QR code inkjet printers to improve their efficiency, the advantages of QR codes continue to be demonstrated. With the development of mobile Internet information technology, each product is assigned a variable QR code to achieve a bag. One code, build a product two-dimensional code tracking and traceability system, and supervise the flow of products throughout the process. This trend will gradually extend to other fields.
