With the continuous development of the food industry, the demand for the packaging machinery industry is increasing. As an important equipment in the packaging industry, inkjet printers have become more widely used in various industries. Before the birth of the inkjet printer, the traditional logo printing forms were various, often using screen printers, pad printers or even more primitive mechanical roller punches to complete the printing. Most of these equipment used pre-printed forms, or In the form of self-adhesive paste, these printing methods can not achieve the synchronization of online production and inkjet printing. Therefore, the application of inkjet printers is becoming more and more extensive. For manufacturing companies, time is money, and inkjet printers undoubtedly maximize the value of the company's production. For a long time, due to the continuous understanding of drug and food safety issues, it has brought a broader development space to the inkjet printer industry. Because the coding function can not only know the production date, but also track potential problems and prevent counterfeiting. The printer is a kind of equipment that is controlled by software and marked on the product. The coding industry is currently one of the packaging machinery industries that are developing rapidly in my country’s market. Nowadays, inkjet printer manufacturers are conducive to product identification and follow-up investigations on product quality. Industrial applications are becoming more and more extensive, and the complexity of corresponding applications is gradually increasing. Manufacturers mark their own products and have their own product marks, which can limit the appearance of counterfeit and shoddy products. In particular, some new and expensive labeling technologies can keep manufacturers better than counterfeit products. The company’s logo is printed on the product, which indicates a promise made by the manufacturer to consumers. Generally, we think that this product is guaranteed, and the quality will be very good, which will greatly enhance the brand image.
