Analysis of the application of hidden printing anti counterfeiting technology

All printing anti-counterfeiting technology can be divided into two categories: dominant anti-counterfeiting technology and recessive anti-counterfeiting technology. I have introduced the application of dominant printing anti-counterfeiting technology before. Today I will introduce the application of recessive anti-counterfeiting technology.

Recessive anti-counterfeiting technology is to realize product anti-counterfeiting through the combination of information technology and packaging and printing technology, which is difficult to distinguish directly by naked eyes. In the early days, the function of anti-counterfeiting with code was realized. The specific method is to use a string of numbers on the bar code to achieve anti-counterfeiting, and then use specific equipment to decode, so as to get the information and anti-counterfeiting identification of goods. At first, the bar code is one-dimensional code, and the information storage is limited. With the development of technology, two-dimensional code technology appeared, whether it is bar code or two-dimensional code, it belongs to recessive anti-counterfeiting technology.

QR code can store a large number of commodity information. Under the specific scanning equipment, it can quickly and accurately get the information of the commodity itself, and also know the processing of the commodity in all aspects of the circulation. The generation of two-dimensional code is also very important. The use of Zhonglang two-dimensional code generation software can quickly generate tens of millions of two-dimensional codes in batches, and the production cost is very low. Therefore, the two-dimensional code anti-counterfeiting technology can be said to be the most extensive and efficient.

But also because the two-dimensional code is easy to make, so it is easy to be copied. When it is used for anti-counterfeiting, it needs to cooperate with a certain database for product anti-counterfeiting. There is also a hidden anti-counterfeiting technology is the bar code technology data symbol, using digital encryption symbols to code the commodity information, which must be used with a certain software, and contains a certain data system, making it difficult to be copied, so as to achieve the anti-counterfeiting function.

Using two-dimensional code to implement anti-counterfeiting can store a large amount of data in the database connected through the Internet, which can not only complete anti-counterfeiting query, but also facilitate more detailed data management tasks such as product origin tracing, product成人英語課程 batch query, production date query, etc., which is also of great significance to the sales management of product manufacturers. The anti-counterfeiting code can be printed with different codes for each product through digital printing technology, so that each product has its own code, and the query link information can be added to directly link to the manufacturer's database server for comparison and query of authenticity
