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 can scan the anti-counterfeiting two-dimensional codes of genuine products in the related technology to obtain the anti-counterfeiting information included in the anti-counterfeiting two-dimensional codes, the anti-counterfeiting two-dimensional codes identical to genuine products can be generated according to the anti-counterfeiting information, namely the current anti-counterfeiting two-dimensional codes are high in reproducibility, and the accuracy of identifying the authenticity of the products through the anti-counterfeiting two-dimensional codes is low. Based on this, the embodiment of the invention provides a printing method and a printing device for an anti-counterfeiting two-dimensional code with printing height, which are described below through embodiments.
Example 1
Referring to fig. 1A, an embodiment of the present invention provides a printing method for an anti-counterfeit two-dimensional code with a printing height. The method specifically comprises the following steps:
step 101: the printing height is selected from a range of preset heights.
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 with the printing height is printed, the more difficult the printing height is accurately measured from the anti-counterfeiting two-dimensional code, so that the reproducibility of the anti-counterfeiting two-dimensional code is reduced.
In an embodiment of the present invention, a preset height range may be set, and when a printing height is selected, a height value is randomly selected from the preset height range as the printing height. For example, assuming a preset height range of 0-50 μm, the randomly selected printing height therefrom may be 11.5 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 printing substrate, determining a height range corresponding to the material type from a preset height range, and randomly selecting a height value from the determined height range 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 height range corresponding to the paper type is preset to be 0-10 μm, the height range corresponding to the plastic type is 11-20 μm, and 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 determined from the preset height range of 0-30 μm according to the plastic type to be 11-20 μm, and then the printing height is randomly selected from the height range of 11-20 μm, and the randomly selected printing height may be 15 μm.
After the printing height is selected through the operation of step 101, the anti-counterfeiting two-dimensional code having the printing height can be printed through the following operations of steps 102 and 103.
Step 102: and generating a three-dimensional anti-counterfeiting image according to the 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 a production control terminal of a certified product manufacturer, the anti-counterfeiting information is packaged into a planar two-dimensional code image, and a third dimension, namely the selected printing height, is increased on the basis of the planar two-dimensional code image to generate a three-dimensional anti-counterfeiting image with the printing height.
Step 103: and printing on a printing substrate corresponding to the product in a three-dimensional printing mode according to the generated three-dimensional anti-counterfeiting image and the preset printing height to obtain the anti-counterfeiting two-dimensional code with the printing height.
The preset printing height is a height value according to which the anti-counterfeiting two-dimensional code is printed, and the preset printing height is equal to the height value of the printing height selected in the step 101. And when the anti-counterfeiting two-dimensional code with the printing height is printed, 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. The three-dimensional printer firstly carries out layering on the three-dimensional anti-counterfeiting image according to the generated three-dimensional anti-counterfeiting image and the preset printing height to obtain a plurality of two-dimensional sub-images. Namely, the three-dimensional anti-counterfeiting image is decomposed into a plurality of planar two-dimensional sub-images according to the preset printing height. In the embodiment of the invention, the heights of all positions of the anti-counterfeiting two-dimensional code printed finally are the same, so that the two-dimensional sub-images of the planes obtained by the decomposition are the same.
And after a plurality of two-dimensional subimages are obtained, overlapping and printing the two-dimensional subimages at the preset position of the printing substrate corresponding to the product in a three-dimensional printing mode to obtain the anti-counterfeiting two-dimensional code with the printing height.
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 curing ink is adopted for spraying the plurality of two-dimensional sub-images in an overlapped mode at the preset position of the printing substrate corresponding to the product, and the overlapping height of the plurality of two-dimensional sub-images is just the printing height, so that the anti-counterfeiting two-dimensional code with the printing height 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 two-dimensional subimages on the preset position of the printing substrate corresponding to the product in an overlapping mode, and the anti-counterfeiting two-dimensional code with the printing height 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. As shown in fig. 1C, the side view of the packing box of the product shows that the anti-counterfeiting two-dimensional code printed by the embodiment of the invention has a certain printing height.
In the embodiment of the invention, the printed anti-counterfeiting two-dimensional code has a certain printing height, 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 (ultraviolet) photocuring ink or silk-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 material type of the printing substrate and the anti-counterfeiting information of the product are correspondingly stored in the corresponding relation among the printing height, the material type and the anti-counterfeiting information.
After the product is on the market, a genuine product manufacturer can randomly inspect the product sold on the market, scan the anti-counterfeiting two-dimensional code corresponding to the product through a microscopic three-dimensional scanning device, obtain anti-counterfeiting information from the scanned anti-counterfeiting two-dimensional code, measure the printing height corresponding to the anti-counterfeiting two-dimensional code, and obtain the material type of the printed substrate corresponding to the product, then inquire the corresponding relation among the stored printing height, material type and anti-counterfeiting information according to the measured printing height, the obtained anti-counterfeiting information and material type, and determine that the product is genuine if the material type, the printing height and the anti-counterfeiting information corresponding to the product can be inquired in the corresponding relation, otherwise, determine that the product is counterfeit. 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, the printing height is selected from a preset height range; generating a three-dimensional anti-counterfeiting image according to the printing height and the anti-counterfeiting information of the product; and printing on a printing substrate corresponding to the product in a three-dimensional printing mode according to the three-dimensional anti-counterfeiting image and the preset printing height to obtain the anti-counterfeiting two-dimensional code with the printing height. According to the invention, the printing height is increased when the anti-counterfeiting two-dimensional code is printed, so that the finally printed anti-counterfeiting code is the three-dimensional anti-counterfeiting code, and the printing height of the generated three-dimensional anti-counterfeiting code is very difficult to measure, so that the reproducibility of the anti-counterfeiting code is reduced, and malicious merchants are difficult to print the anti-counterfeiting code with the same printing height as that of genuine manufacturers, so that the accuracy of identifying the authenticity of the product through the height information of the anti-counterfeiting code is improved, and the genuine manufacturers can also identify the malicious merchants imitating the product through the printing height and pursue the blame of the malicious merchants.
