The advantage of UV inkjet printer is that it breaks through the bottleneck of printing technology, is not restricted by any material, and can realize inkjet marking on various materials, which truly realizes that printing can be completed at one time without plate making. In terms of printing effect, UV inkjet printers also solve a series of problems of common ink inkjet printers, such as ink drop after encountering strong acid and strong alkali. In practical applications, it is more suitable for modern production enterprises. Especially in the aspect of barcode traceability, UV machine can be said to perform well. First of all, with the high dpi piezoelectric nozzle, it can achieve A-level barcode printing, and a series of traceability background associations such as database query correlation, which plays a good role in the appearance of the product and traceability and anti-counterfeiting. The role of. To sum up, it has the following advantages: 1. Instant curing, no need to wait. 2. It is suitable for a wide range of materials and good printing effect. 3. There is no volatile toxic pollutant VOC emission in line with the new standard. 4. Hardness and softness after curing can choose different inks, which are resistant to friction. 5. After curing, it is resin composition, resistant to alcohol, ketones, and other acids and alkalis. 6. The ink will not evaporate and dry for a long time, and the nozzle will not be easily clogged. The UV digital inkjet printing system adopts a modular design, each printing unit is highly integrated, and can be easily installed on various roll paper, roll film, sheet-fed printing machines, and numerous post-press processing equipment to easily realize roll film. The variable data printing requirements of a single sheet can also be integrated and installed on the customer's existing equipment to quickly form production capacity and improve production efficiency. At present, it has been applied in many fields such as drug supervision code, veterinary drug QR code, rainbow code, blog code, Hanxin code, and can seamlessly connect with enterprise management systems (such as ERP systems) for real-time online printing.
