Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In consideration of the fact that malicious merchants in the related technology can scan the anti-counterfeiting two-dimensional code of the genuine product to obtain the anti-counterfeiting information included in the anti-counterfeiting two-dimensional code, the anti-counterfeiting two-dimensional code which is the same as that of the genuine product manufacturer can be generated according to the anti-counterfeiting information, namely the current anti-counterfeiting two-dimensional code is high in reproducibility, so that the accuracy of identifying the authenticity of the product through the anti-counterfeiting two-dimensional code is low. Based on this, the embodiment of the invention provides a printing method and a printing device for anti-counterfeiting two-dimensional codes with different printing heights. The following is described by way of example.
Example 1
Referring to fig. 1, an embodiment of the present invention provides a printing method for anti-counterfeit two-dimensional codes with different printing heights. The method specifically comprises the following steps:
step 101: and selecting preset N printing heights from the preset height range, wherein N is an integer greater than 1.
The height unit of the above-mentioned predetermined height range may be a very small height unit, for example, the height unit may be in the order of micrometers, and the predetermined height range may be 0 to 50 μm or 0 to 30 μm, etc. The embodiment of the invention does not specifically limit the specific range of the preset height range, and can be set according to specific requirements in actual operation. The smaller the set height unit is, the printing height is selected from the preset height range subsequently, and when the anti-counterfeiting two-dimensional code is printed according to the selected printing height, the more difficult the printing height is to be accurately measured from the printed anti-counterfeiting two-dimensional code, so that the reproducibility of the anti-counterfeiting two-dimensional code is reduced.
In the embodiment of the present invention, a preset height range may be set, and when the printing height is selected, N different height values are randomly selected from the preset height range as the printing height, where N is an integer greater than 1. For example, assuming the preset height range is 0-50 μm and N is 2, 2 printing heights randomly selected from 0-50 μm may be 11.5 μm and 13 μm.
In addition to the above-described random selection of printing heights from a predetermined height range, embodiments of the present invention may also combine the selection of printing heights with the type of material of the printed substrate. The printing substrate is a substrate for printing the anti-counterfeiting two-dimensional code, and the type of the printing substrate can be paper, canvas, plastic, a film or organic glass and the like. The selection of the printing height is combined with the material type of the printed substrate, so that the confidentiality of the selected printing height can be further improved, and the reproducibility of the anti-counterfeiting two-dimensional code is further reduced.
The selection mode combining the selection of the printing height and the material type of the printing substrate specifically comprises the following steps: according to the material type of the printed substrate, determining a height range corresponding to the material type from a preset height range, and randomly selecting N preset different height values from the determined height range to serve as the printing height.
In the embodiment of the present invention, the height ranges corresponding to different material types may be preset, and the preset height range covers the height ranges corresponding to all the material types. For example, assuming that the material type includes three types of paper, plastic and canvas, the preset height range corresponding to the paper type is 0-10 μm, the height range corresponding to the plastic type is 11-20 μm, the height range corresponding to the canvas type is 21-30 μm, the preset height range may be 0-30 μm, assuming that the material of the printing substrate of the product is the plastic type, the corresponding height range is 11-20 μm determined from the preset height range 0-30 μm according to the plastic type, assuming that N is 2, 2 height values are randomly selected from the height range of 11-20 μm as the printing height, and the randomly selected 2 printing heights may be 11.5 μm and 15 μm, respectively.
In the embodiment of the invention, because N preset printing heights are selected from the preset height range, and N is an integer greater than 1, the surface of the anti-counterfeiting two-dimensional code printed according to the selected printing heights has the characteristic of fluctuation, a malicious merchant is difficult to measure each printing height from the printed anti-counterfeiting two-dimensional code, and the reproducibility of the anti-counterfeiting two-dimensional code is greatly reduced.
After the preset N printing heights are selected through the operation of step 101, the anti-counterfeiting two-dimensional code with the preset N printing heights can be printed through the following operations of step 102 and step 104.
Step 102: and respectively setting the printing position corresponding to each selected printing height.
The printing position is a specific position of the printing height in the anti-counterfeiting two-dimensional code, for example, the printing position can be the upper left corner or the upper right corner of the anti-counterfeiting two-dimensional code. In order to more accurately represent the printing position corresponding to each printing height, the printing position corresponding to the printing height can be represented by using a pixel area covered by the printing height, namely, the heights in the pixel area in the anti-counterfeiting two-dimensional code produced subsequently are the printing heights corresponding to the pixel area.
In the embodiment of the present invention, a plurality of printing positions may be preset, and when a printing position corresponding to each printing height is set, preset N printing positions are randomly selected from the preset plurality of printing positions, where N is an integer greater than 1, and the selected preset N printing positions are respectively allocated to the selected preset N printing heights.
Step 103: and generating a three-dimensional anti-counterfeiting image according to each printing height, the printing position corresponding to each printing height and the anti-counterfeiting information of the product.
The anti-counterfeiting information of the product can comprise a unique identifier of the product or description information related to genuine product authentication and the like. The anti-counterfeiting information of the product can be acquired from the production control terminal of a certified product manufacturer, and a two-dimensional anti-counterfeiting image corresponding to the product is generated according to the anti-counterfeiting information of the product. And then, according to each printing height and the printing position corresponding to each printing height, performing three-dimensional transformation on the two-dimensional anti-counterfeiting image to obtain a three-dimensional anti-counterfeiting image corresponding to the product.
When the two-dimensional anti-counterfeiting image is subjected to three-dimensional transformation, each printing position is firstly determined in the two-dimensional anti-counterfeiting image, a third dimension is added at each determined printing position, namely, the printing height corresponding to each printing position is respectively added at each determined printing position, and therefore the three-dimensional anti-counterfeiting image with the preset N printing heights is generated.
Step 104: and printing the anti-counterfeiting two-dimensional code with the preset N printing heights on the printing substrate corresponding to the product in a three-dimensional printing mode according to the generated three-dimensional anti-counterfeiting image.
And uploading the three-dimensional anti-counterfeiting image to a three-dimensional printer or artificially storing the three-dimensional anti-counterfeiting image in the three-dimensional printer when printing the anti-counterfeiting two-dimensional code with the preset N printing heights. The three-dimensional printer firstly carries out layering on the three-dimensional anti-counterfeiting image according to each printing height and the printing position corresponding to each printing height to obtain a plurality of two-dimensional sub-images. The three-dimensional anti-counterfeiting image is decomposed into a plurality of planar two-dimensional sub-images according to the printing height and the printing position corresponding to the printing height. In the embodiment of the invention, the heights of all positions of the anti-counterfeiting two-dimensional code printed finally are different, so that the two-dimensional sub-images of the planes obtained by the decomposition are different.
And after a plurality of different two-dimensional subimages are obtained, a plurality of different two-dimensional subimages are printed in an overlapped mode at the preset position of the printing substrate corresponding to the product in a three-dimensional printing mode, and the anti-counterfeiting two-dimensional code with the preset N printing heights is obtained. Because the two-dimensional sub-images of the planes are different, the surface of the anti-counterfeiting two-dimensional code obtained by printing the two-dimensional sub-images in an overlapped mode at the same position has the characteristic of fluctuation.
The three-dimensional printing method may be an Ultraviolet (UV) curing inkjet method or a screen printing method. When the UV curing ink-jet mode is adopted for printing, the UV light-curing ink is adopted for spraying the plurality of different two-dimensional sub-images in an overlapped mode at the preset position of the printing substrate corresponding to the product, and after the plurality of different two-dimensional sub-images are overlapped, the surface height of the obtained anti-counterfeiting two-dimensional code is fluctuated, so that the anti-counterfeiting two-dimensional code with the preset N printing heights is obtained. The UV light-cured printing ink has the characteristics of high hardness, scratch resistance and strong drug resistance, and is good in color reproducibility, and anti-counterfeiting two-dimensional codes printed by the UV light-cured printing ink can be kept for a long time and are not easy to damage.
When a screen printing mode is adopted, screen printing ink is adopted to print the plurality of different two-dimensional subimages at the preset positions of the printing substrates corresponding to the product in an overlapping mode, and the anti-counterfeiting two-dimensional code with the preset N printing heights is obtained.
In the case of printing the forgery-preventing two-dimensional code by the UV curing ink-jet method or the screen printing method, single black printing is used, and cyan, magenta, yellow, and register colors of CMYK (cyan magenta yellow key plate, printing color pattern) are set to 0, and 100, respectively, in the single black printing.
As shown in fig. 1B, the anti-counterfeit two-dimensional code is printed on the printed substrate corresponding to the product, which may be printed on the packaging box of the product. The side view of the packing box of the product shown in fig. 1C shows that the surface of the anti-counterfeiting two-dimensional code printed by the embodiment of the invention is fluctuated and has a plurality of different printing heights.
In the embodiment of the invention, the printed anti-counterfeiting two-dimensional code has a plurality of different printing heights, so that the reproducibility of the anti-counterfeiting two-dimensional code is reduced, and the anti-counterfeiting concealment performance and the anti-counterfeiting effect of the anti-counterfeiting two-dimensional code are improved. The ink layer of the anti-counterfeiting two-dimensional code printed in the embodiment of the invention is UV photocuring ink or screen printing ink, the ink curing and drying speed is high, the ink layer has good luster and bright color, and the anti-counterfeiting two-dimensional code has high water resistance and wear resistance.
After the anti-counterfeiting two-dimensional code with the printing height is printed, the printing height, the printing position corresponding to the printing height, the material type of the printed substrate and the anti-counterfeiting information of the product are correspondingly stored in the corresponding relation among the printing height, the printing position, the material type and the anti-counterfeiting information.
After the product is on the market, a certified manufacturer can randomly inspect the product sold on the market and scan the anti-counterfeiting two-dimensional code corresponding to the product through microscopic three-dimensional scanning equipment; acquiring anti-counterfeiting information from the scanned anti-counterfeiting two-dimensional code, and measuring each printing height corresponding to the anti-counterfeiting two-dimensional code; respectively determining a printing position corresponding to each printing height from the anti-counterfeiting two-dimensional code, and acquiring the material type of a printing substrate corresponding to the product; and inquiring the corresponding relation among the printing height, the printing position, the material type and the anti-counterfeiting information according to the measured printing height, the determined printing position corresponding to the printing height, the obtained anti-counterfeiting information and the obtained material type, if the corresponding relation can inquire the printing height, the printing position, the material type and the anti-counterfeiting information corresponding to the printing height, the printing position corresponding to the printing height and the anti-counterfeiting information corresponding to the product, determining that the product is a genuine product, and otherwise, determining that the product is a counterfeit product. When the product is determined to be a counterfeit, the genuine manufacturer can blame a malicious merchant that produces the counterfeit.
In the embodiment of the invention, N preset printing heights are selected from a preset height range, wherein N is an integer greater than 1; setting a printing position corresponding to each printing height; generating a three-dimensional anti-counterfeiting image according to each printing height, the printing position corresponding to each printing height and the anti-counterfeiting information; and printing the anti-counterfeiting two-dimensional code with the preset N printing heights on the printing substrate according to the three-dimensional anti-counterfeiting image. Because the anti-fake two-dimensional code of printing has a plurality of different printing heights, this anti-fake two-dimensional code has the height and fluctuates, because the measurement degree of difficulty of each printing height of the anti-fake two-dimensional code that generates is very high, the reproducibility of anti-fake two-dimensional code has been reduced, malicious trade company hardly prints the anti-fake two-dimensional code the same with genuine goods producer, the improvement is through the accuracy of anti-fake two-dimensional code authentication product true and false, genuine goods producer accessible has the anti-fake two-dimensional code of height and fluctuation to imitate the malicious trade company of its product.
