The emergence of QR code as a new thing has promoted the development of many industries. With the emergence of QR codes, many industries have undergone tremendous changes. In recent years, it has been seen everywhere that two-dimensional codes are needed in life, or patterns of two-dimensional codes are seen on product packaging. It can be said that because of the popularization of QR codes, the industry development of inkjet printers has also changed. Derived a UV inkjet printer that is more in line with the needs of the times. Two-dimensional code is an information technology that uses a certain geometric shape to record data in a pattern distributed on a plane according to a certain rule. Compared with one-dimensional code, radio frequency identification and other technologies, it has a small area to carry a large amount of information, the cost of reading is low, and the security and confidentiality are higher. Combined with the current mobile communication network of mobile phones, the two-dimensional code can also provide people with Various mobile application services, which are currently an important means of realizing the Internet of Things. After the widespread use of two-dimensional codes, many inkjet printer manufacturers have begun to develop special coding equipment, such as UV inkjet printers, two-dimensional code inkjet printers and so on that we know can complete the two-dimensional code assignment. Code work. It is reported that the JW5000 series of UV inkjet printers developed by the Guangzhou Jiangwei inkjet printer manufacturer has the functions of anti-counterfeiting traceability and a recognition rate of more than 90%. In terms of performance, it is more comprehensive and stable. Nowadays, companies in many industries have used UV inkjet printers to assign variable data QR codes to their products. It can be said that the emergence of two-dimensional code inkjet printers has brought more convenience to enterprises, and has also changed people's concept of life and consumption.
