Two-dimensional code is also called two-dimensional bar code. The common two-dimensional code is QR code, which is also an upgraded version of bar code. It can store more information and express more data types with powerful functions. Up to now, commodity control is strict, and the two-dimensional code that realizes the identification of product packaging information is common. At the same time, the two-dimensional code inkjet UV inkjet printer is popular. The inkjet printer manufacturer recommends cost-effective equipment in accordance with the production situation of the customer. In all aspects Significantly improved, and the scope of application has been further expanded. Variable two-dimensional code has high-density coding, large information capacity, wide coding range, low cost, easy to make, and long retention time. So everyone habitually chooses inkjet printers. The circulation of market commodities requires packaging, and its packaging must be relevant Commodity information identification, especially two-dimensional codes, barcodes, it is more suitable to use inkjet printers for inkjet processing. Today's two-dimensional code printing UV inkjet printer is a new type of coding equipment. Its advantage is that it breaks through the bottleneck of printing technology and realizes high-speed coding without any material restrictions. The two-dimensional code printing system is more suitable for modern applications in practical applications. Industrial production enterprises. The generation of QR codes mainly relies on black and white or color graphics. The equipment mainly tests the stability of ink and print heads, supports seamless splicing of multiple sets of print heads, so that the printing speed is continuously accelerated, and the purchase cost is saved for enterprise users. Users use two-dimensional code printing UV inkjet printers to mark products, which is beneficial for identification, product tracking, preventing counterfeiting, and increasing added value. It not only meets the needs of various industries and applications, but also improves product supply speed and improves market response efficiency.
