Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0038] Such as figure 1 The invisible encrypted two-dimensional code printing and identification method of the shown embodiment includes:

[0039] S1, using the QR code management system to generate encrypted QR code files;

[0040] S2, using off-line direct plate-making CTP equipment (CTP: Computer-to-plate, off-line direct plate-making) to output the encrypted two-dimensional code file to the printing plate;

[0041] S3, installing the printing plate in S2 on a certain color group of the printing equipment, and printing with invisible ink;

[0042] S4, after the operation of S3, a printed semi-finished product containing an invisible encrypted two-dimensio...

Abstract

The invention discloses a printing and recognition method for an invisible and encrypted two-dimension code. In combination with dual anti-fake characteristics of the encrypted two-dimension code and invisible ink, anti-fake information can be recognized only by professional reading equipment, and therefore the anti-fake performance is improved. By the utilization of the technology, the information of the encrypted two-dimension code can be displayed under ultraviolet or infrared lamplight, and then the professional reading equipment is used for reading the encrypted information in the two-dimension code, so that the dual anti-fake purpose is achieved to improve the anti-fake performance.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a method for printing and identifying an invisible encrypted two-dimensional code. Background technique [0002] The use of two-dimensional code technology is quite mature, and two-dimensional codes also have stable production technology, but the current two-dimensional code printing, whether it is a fixed code or a variable data code, is printed with black or dark ink. Moreover, the common two-dimensional code technology is public, and its information is not protected. The information in the universal QR code is not encrypted and can be easily read and reused. Even encrypted QR codes can be directly scanned, copied and reused in the case of colored ink printing. Colored inks are widely used. Ordinary signs, texts and other information printed with this ink are easy to be copied, with poor concealment and reduced anti-counterfeiting performance. [0003] The two-d...
