Multiple anti-fake printing production method of products such as certificates and credentials and identification method thereof

Abstract

The invention relates to a multiple anti-fake printing production method of products such as certificates and credentials, which comprises the following steps of: 1) stamping a magnetic strip on the products such as certificates and credentials; 2) printing the product serial number at a place different from the magnetic strip and adopting the fluorescent black ink doped with red for printing; 3) conducting magnetic writing to a second track of the magnetic strip, wherein the magnetic writing content is consistent with the product serial number; and 4) when the user issues the certificates to the certificate users, associating the magnetic strip with the ID number of the certificate user in a client computer information system by reading the information in the magnetic strip by a magnetic reader and corresponding to the ID number of the certificate user. The method enhances the difficulty in counterfeiting from the aspect of technical anti-counterfeiting by the multiple anti-fake process, and the product number is corresponding to the computer database, thus avoiding the problem of fake certificate from the aspect of information anti-counterfeiting.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting printing, in particular to a method for making and identifying multiple anti-counterfeiting printings for certificate products. Background technique [0002] Anti-counterfeiting printing has always been an important anti-counterfeiting measure and the focus of anti-counterfeiting methods. It is also a long-term task for domestic finance, taxation and other related departments. In the past, anti-counterfeiting measures were mainly aimed at paper, ink, printing color, etc. Watermarking has been adopted Paper, fluorescent ink, colorless fluorescent ink, color-changing ink, multi-color overprinting and other methods have been used in the anti-counterfeiting printing of tickets and have achieved some results. However, due to the high cost and the difficulty of being directly identified by consumers, the use of the above measures has been restricted. It must be restricted, and the actual eff...

[0002] Anti-counterfeiting printing has always been an important anti-counterfeiting measure and the focus of anti-counterfeiting methods. It is also a long-term task for domestic finance, taxation and other related departments. In the past, anti-counterfeiting measures were mainly aimed at paper, ink, printing color, etc. Watermarking has been adopted Paper, fluorescent ink, colorless fluorescent ink, color-changing ink, multi-color overprinting and other methods have been used in the anti-counterfeiting printing of tickets and have achieved some results. However, due to the high cost and the difficulty of being directly identified by consumers, the use of the above measures has been restricted. must be limited, the actual effect is not good

Coupled with the fact that counterfeiters have mastered these printing methods, the anti-counterfeiting function becomes weaker, and it is difficult for users to distinguish the authenticity
