The so-called inkjet printer is an inkjet printer controlled by an industrial motherboard through a computer program or computer software, which performs analog-to-digital conversion of the analog signal on the spot, and then facilitates user operation and control. The computer inkjet printer is a kind of Equipment such as plastic packaging, paper outer packaging and other materials that print production dates, batch numbers, type standards, trademarks and anti-counterfeiting marks, graphics, two-dimensional codes, quantum cloud codes, barcodes, etc. on the surface of different types of objects are also classified as UV sprays. A kind of code machine. Under normal circumstances, computer inkjet printers are widely used in product packaging and marking. With the development of scientific and high-skills, domestic inkjet printers can reach the level of imported inkjet printers in terms of machine function or inkjet function. With the quiet rise of machines, it has also promoted the further development of domestic marking skills, especially large and medium-sized enterprises, which attach more importance to coding equipment as the new sign darling. The computer inkjet printer (UV inkjet printer) is assembled with imported industrial-grade piezoelectric nozzles, which are characterized by high speed, stability, long life, easy to protect and maintain, so that UV ink can be more circulated and achieve better effects. 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 an abnormality occurs, making the production safer and more reliable. The primary occupations used by inkjet printers are: food occupations, flexible packaging occupations, pharmaceutical occupations, cosmetics occupations, lighting appliances occupations, car parts occupations, plastic pipe occupations, health care products occupations, carton occupations, card ticket occupations, labeling occupations, electronic appliances occupations , Tobacco industry, etc.
