The so-called inkjet printer is an inkjet printer controlled by a computer program or computer software with an industrial motherboard, and performs analog-to-digital conversion of the analog signal on the spot, so as to facilitate user operation and control. The computer inkjet printer is a kind of Equipment that prints production date, batch number, model specifications, trademarks and anti-counterfeiting marks, graphics, two-dimensional codes, quantum cloud codes, barcodes, etc. on the surface of different materials such as plastic packaging and paper outer packaging and different types of objects are also UV sprays. A kind of code machine. Under normal circumstances, computer inkjet printers are widely used in product packaging and identification. With the mature development of science and technology, domestic inkjet printers can reach the level of imported inkjet printers in terms of machine performance and coding effect. While the machine is quietly emerging, it has also promoted the further development of domestic identification technology, especially large and medium-sized enterprises, paying attention to the coding equipment as the new identification darling. Computer inkjet printers (UV inkjet printers) assemble imported industrial-grade piezoelectric nozzles, which are characterized by high speed, stability, long life, easy maintenance, and make UV ink smoother and achieve the best results. UV inkjet printer software is easy to learn, It is easy to understand and can be operated independently in a short time. The machine comes with UPS, and the data can be saved in time if abnormality occurs, making production safer and more reliable. The main application industries of inkjet printers are: food industry, flexible packaging industry, pharmaceutical industry, cosmetics industry, lighting appliance industry, auto parts industry, plastic pipe industry, health care product industry, carton industry, card ticket industry, label industry, electronic and electrical industry , Tobacco industry, etc.
