In the field of packaging and labeling, it includes explicit anti-counterfeiting technology and stealth anti-counterfeiting technology. Part of the explicit anti-counterfeiting is to indicate whether the packaging or the label has been artificially damaged, and the damage can be clearly judged by the human eye without any tools, and without destroying the packaging and the label itself. Invisible anti-counterfeiting is more technical and better able to protect its packaging and labeling products.
The dominant anti-counterfeiting technology mainly relies on anti-counterfeiting materials and appearance packaging and printing, which are easy to see directly, such as anti-counterfeiting paper and anti-counterfeiting tape.
Invisible anti-counterfeiting is accomplished through the combination of information technology and packaging and printing technology, which is difficult to distinguish directly with the naked eye.
At present, the relatively new invisible anti-counterfeiting technology adopts the RFID chip-radio frequency chip technology. Print or package radio frequency electronic circuit structures on packaging, labels, and store various types of information and anti-counterfeiting labels. Once peeled off from the label or item, it will not work properly. When it is necessary to read or identify the authenticity of the goods, we can use the corresponding reader to read its electronic signals, and this reading is very fast and accurate. RFID technology is very safe and reliable for anti-counterfeiting, but it still needs to be further reduced in the cost of production. At the printing exhibition of drupa2012, printing of organic electronic materials has appeared. In the near future, "large and stable reproduction of organic electronic materials by printing process" will become a reality, so that radio frequency technology can be more widely used. .
In the early stage of the development of commodity economy, the use of code security, its anti-counterfeiting is to use a string of numbers on the bar code, using a specific device for decoding analysis, so as to obtain various types of information and anti-counterfeiting labels. The original bar code is one-dimensional, containing only 10 to 20 numbers, and the storage of information is limited. With the development of technology, two-dimensional code technology has emerged, which belongs to stealth anti-counterfeiting technology. Today's QR code can store a large amount of product information and can hold thousands of characters. Under a specific scanning device, it can quickly and accurately obtain information other than the product itself, and can also know the processing of each link in the circulation of the product, which is impossible to do with the amount of data to be encoded.
With the continuous development of printing technology, more and more enterprises will accelerate the pace of research and development in the safety and anti-counterfeiting of their own products. As long as someone in the market is going to copy, steal, or tamper with anti-counterfeiting technology, there are conditions. Whether it is explicit anti-counterfeiting or invisible anti-counterfeiting, even the combination of the two is to make their goods better protected. Cost is also a major consideration for merchants, so cost and security must be optimized. Through the above discussion, the author believes that the future anti-counterfeiting technology must be a combination of explicit anti-counterfeiting and invisible anti-counterfeiting. In particular, the introduction of information technology anti-counterfeiting methods can greatly enhance the reliability of anti-counterfeiting, and for manufacturers, it can also The timely feedback of the market situation to its own sales system will greatly help the statistical management of production and sales data.
