With the advocacy and implementation of Industry 4.0 and the call of China Smart Manufacturing 2025, many Internet of Things companies have responded to their respective strengths and developed and produced anti-counterfeiting traceability based on Internet of Things technology. The concept of one thing, one code was born from this. , The so-called one item, one code refers to one commodity and one identity, which can check the authenticity and information of the commodity. One thing one code includes barcodes, QR codes, PDF417 codes, Hanxin codes and other code types, which are printed on the surface of each product as the basic information carrier for the anti-counterfeiting traceability of the Internet of Things. As a modernized brand-new information storage, transmission and recognition technology, two-dimensional code has been widely used in all walks of life. In recent years, two-dimensional codes have developed rapidly, and two-dimensional codes can be seen everywhere in life. The content forms of variable data two-dimensional codes include: Chinese and English, database, garbled, random code, anti-counterfeiting code, etc. The carton inkjet printer takes this opportunity to realize the dynamic generation of two-dimensional codes through the innovation of system software, to carry out perfect brand promotion for merchants, and at the same time to expand the scope of space for merchants' brand promotion. In terms of product identification, the carton inkjet printer uses a QR code as the carrier for information transmission. Scan the QR code to quickly find the basic information of the whole box product, including product name, product model, product batch, production date and production location And so on, and there are anti-counterfeiting traceability functions. The use of two-dimensional codes is driving the presentation industry to further improve the technology of Ru0026D and production. For inkjet printers, an important marking device, the printing of two-dimensional codes is not a big problem. The important thing is to speed up the work speed and quality of inkjet printers. At present, the high-end models in the industry have achieved good results in printing QR codes, and the recognition rate of the QR codes has reached 80%~95%. However, for the broad application market of QR codes in the future, the technology of inkjet printers still needs Keep improving to achieve technological breakthroughs and create more secure QR code products.
