Description
The technical field is as follows:
the invention relates to an anti-counterfeiting printing technology, in particular to a triple anti-counterfeiting two-dimensional code with pseudo-random information overprinting digital fluorescent images, which can be used for anti-counterfeiting of various printed products.
The background technology is as follows:
the current common anti-counterfeiting methods include the following: the first is a laser anti-counterfeiting mark, the logo or special identification pattern of the product is printed into an anti-counterfeiting label of the product by using a laser recessive ink fluorescent ink printing technology, and the same type of product uses the same label, so that the anti-counterfeiting label is easy to forge, and the forged anti-counterfeiting label is used on a fake product, so that the authenticity of the product is confused, and the effective anti-counterfeiting is difficult. The second is the password antifake label, its adopted method is that each product encodes a series of numbers, the code of each product is different, print this number on the label and cover up, store this number in the computer database that can supply consumer to inquire at the same time, when consumers purchase products, the number on the sign inputs the number on the computer database to compare and discern through the telephone or network computer, the same is true, the difference is false, the method is simple, discern easy, difficult counterfeit, but in the actual use, print the label after the code data is unified and produced by the computer. The true and false code data representing the product can be copied illegally to be counterfeited, meanwhile, the code can also recycle the code on the product which is not inquired to be counterfeited to be attached to the fake product, and the anti-counterfeiting effect is difficult to ensure. The third is texture anti-counterfeiting, the texture feature on the label is used for anti-counterfeiting, and the label is difficult to forge, but only the serial number of the label is set and is a plain code, each label can be repeatedly inquired, and counterfeiters can forge the serial number on the label and the necessary texture feature reflected in inquiring, namely whether the phenomenon exists in a square or not, in batches according to the feature after the counterfeiters copy the serial number on the label and the necessary texture feature in inquiring by a warehouse custodian or a salesperson. The fourth is metameric ink anti-counterfeiting, which is an anti-counterfeiting printing technology based on metameric phenomenon, namely, two substances are used for representing the same color under one light source, but representing different colors under the other light source, so that anti-counterfeiting is realized, the metameric proportion is easy to determine, and therefore, the anti-counterfeiting effect is difficult to ensure.
In summary, the existing anti-counterfeiting methods have certain defects, so that the counterfeiting of the product cannot be prevented at all.
The invention comprises the following steps:
aiming at the defects of the existing anti-counterfeiting printing technology of various printed products, the invention improves the existing technology, and provides a triple anti-counterfeiting two-dimensional code with pseudo-random information overprinting digital fluorescent images.
The four colors of cyan, yellow and black are generally described by CMYK, and metamerism generally refers to that the CMYK four inks of color printing form a group of matching color matching inks, and the inks are the same color, namely the same color, when seen under visible light; under infrared light, the color spectrum difference, i.e. the different spectrum, is generated by different proportions of the CMYK four inks, and the inks can show different colors, which is called metamerism.
The technical scheme adopted for solving the technical problems is as follows: generating a two-dimensional code image by two-dimensional code information, namely a clear code two-dimensional code image, encrypting and scrambling the two-dimensional code information to generate a pseudo-random binary information stream, generating the pseudo-random information image by using the pseudo-random binary information stream, dividing color blocks in color block diagrams of the pseudo-random information image and the clear code two-dimensional code image into black color blocks and white color blocks, printing a digital fluorescent image, the pseudo-random information image and the clear code two-dimensional code image together in an overlapping manner, printing the digital fluorescent image firstly, then printing the pseudo-random information image and the clear code two-dimensional code image on the digital fluorescent image in a fully overlapping manner by using metameric color matching ink, enabling the color blocks of the pseudo-random information image and the clear code two-dimensional code image to be overlapped together in a one-to-one correspondence manner, enabling the color blocks of the pseudo-random information image and the clear code two-dimensional code image to be required to be displayed in a white color under visible light and enabling the pseudo-random information image to be required to be displayed in a white color under the visible light, enabling the first color block clear code two-dimensional code image to be required to be displayed in a white color under the infrared light and enabling the pseudo-random information image to be required to be displayed in a white color under the infrared light, enabling the second color block clear code two-dimensional code image to be required to be displayed in a white under the visible light, and the red under the infrared light required to be displayed in a white condition under the visible light and the visible light required to be displayed in a white on the white black image and a black-black image and required to be displayed under the visible light and a black image and a black-black image and a visible image and visible condition is required to be displayed,
using CMYK four-color ink to generate four groups of matching color matching ink composed of CMYK four-color ink, wherein the ratio of the four-color ink of the first group of matching color ink is C 1 M 1 Y 1 K 1 And the first group of color matching ink shows white color under visible light and infrared light through proportion color matching, and the four-color ink proportion of the second group of color matching ink is C 2 M 2 Y 2 K 2 And the second set of color matching inks are rendered black under visible light by proportioningColor, white in infrared light, the ratio of four inks of the third color combination ink is C 3 M 3 Y 3 K 3 And the third color matching ink is enabled to show white color under visible light and black color under infrared light through proportion color matching, and the proportion of the four inks of the fourth color matching ink is C 4 M 4 Y 4 K 4 And the fourth color matching ink is enabled to display black under visible light and infrared light through proportion color matching,
