Anti-counterfeiting traceability has always been an issue of great concern to all walks of life. With the development of science and technology, coding and marking equipment has more and more functions, which can be used not only for inkjet printing, but also for anti-counterfeiting traceability. Due to the mixed market, counterfeit and inferior products are common, and it is difficult for consumers to distinguish the difference between regular products and fake and inferior products, which harms the interests of consumers and enterprises. In this context, the one-code one-code anti-counterfeiting traceability technology emerged at the historic moment. The one-item one-code technology is to assign each product online or offline through the coding equipment, and the data collection function binds the products one-to-one. The traceable source code of the ink jet coding equipment on the product packaging is a two-dimensional code, a barcode, etc., so that consumers and law enforcement agencies can obtain detailed information of the product by scanning the code. How to prevent the retrospective source code from being destroyed? The data information can capture the number of times the source code has been queried. If it is queried for the first time, it can basically be determined that the product is a genuine merchant. This also dispels consumers' worries about buying second-hand and inferior products. Scanning the code to obtain information does not require any identification skills, the results are true and reliable, which greatly improves the reputation of the brand and the trust of consumers in the brand, so as to stand out in the fierce food market competition. The traceable source code is based on the one-object-one-code technology. The presentation method can be two-dimensional code, barcode, one-dimensional code, etc. The specific code format used can be determined according to the actual situation. Arnoldjet provides ink jet coding equipment, and its service tenet is committed to providing customers with high quality and stable ink jet coding equipment. When the equipment is printing on the machine, it does not directly touch the surface of the article and will not damage the food packaging. The printed logo usually has the characteristics of high adhesion and abrasion resistance, which can ensure the bar code and two-dimensional in the food circulation process. Long-term availability of code information. Packaging ink coding equipment not only has fast printing speed and wide application range, but also can mark high-quality marks on the surface of a variety of materials. Its variable data printing characteristics can solve the problems of one item, one code, anti-counterfeiting and anti-smuggling.
