Detailed Description
The invention will be described in further detail with reference to the following figures and specific examples, without limiting the scope of the invention.
As shown in fig. 1 to 4, the anti-counterfeiting random marker according to the embodiment includes a printing stock, and further includes a substrate layer 1 covering the printing stock, a color permeable layer 2 covering the substrate layer, and a texture layer 3 located on the color permeable layer; the color-permeable layer is used for mutually repelling with UV printing ink of the texture layer to enable the UV printing ink of the texture layer to form random texture bulges and texture gaps between the texture bulges on the color-permeable layer, and the color-permeable layer enables the color of the substrate layer to be permeable and is used for forming color difference with the texture layer.
The stock can be paper or other materials such as be used for printing the label or for article extranal packing etc. again, wherein the substrate layer is colored UV printing ink printing, it is used for setoff subsequent texture layer, the layer of penetrating look is transparent UV printing ink layer generally, the texture layer is printed and possesses mutually exclusive UV printing ink with the UV printing ink of the layer of penetrating look for with the colored UV printing ink that substrate layer colour is poor great, after the layer of penetrating look printing finishes, when solidifying is incomplete, print the texture layer on the layer of penetrating look again, wherein the texture layer takes place the mutual exclusion with the layer of penetrating look after printing on the layer of penetrating look, promptly: as shown in fig. 1 and fig. 2, the two UV inks are mutually hydrophobic, and the UV ink used in the texture layer makes the texture layer become a corresponding random feature layer composed of texture ridges a1 and texture gaps a2 due to the self-tension, and then the texture layer is cured, so as to obtain the random marker applied with the anti-counterfeiting function.
In the anti-counterfeiting random marker of the embodiment, an identification code area layer is coated in a local area of the anti-counterfeiting random marker or on a printing stock, and an identification code displayed by the identification code area layer 4 is a two-dimensional code; the substrate layer and the texture layer are different in color, generally, the substrate layer is darker in color, such as dark blue or black, and the texture layer and the substrate are different in color system, such as red or yellow; the textured layer has a thickness greater than the thickness of the color permeable layer, wherein the thickness of the textured layer generally refers to the height of the textured ridges formed.
One basic anti-counterfeiting principle of the anti-counterfeiting random marker in the embodiment is as follows: when leaving the factory, gather characteristic information through equipment, promptly: acquiring texture layer characteristics of an irregular anti-counterfeiting random marker and a two-dimensional code of an identification code area layer by using a linear array camera, and then transmitting the texture layer characteristics and the two-dimensional code to a server, for example, uploading the acquired pictures to the server, calculating the characteristics of each anti-counterfeiting random marker into digital data by using a texture layer marking algorithm and storing the digital data in the server, photographing the anti-counterfeiting random marker by using mobile terminal equipment and uploading the digital data to the server when in actual use, searching original data on the server by using two-dimensional code information in the uploaded anti-counterfeiting random marker picture by using the server, comparing the original data with the data obtained by analyzing and calculating the characteristics in the newly uploaded anti-counterfeiting random marker picture, and performing true and false judgment and feeding back the result to a mobile terminal query result; the inquiry person can also change the angle of the anti-counterfeiting random marker slowly until the anti-counterfeiting random marker is horizontally placed, and the color of the raised grains can be seen by human eyes and the color of the substrate layer can not be seen gradually due to the raised grains on the grain layer.
By utilizing the scheme, the anti-counterfeiting random marker can effectively realize the anti-counterfeiting of the random characteristics with lower manufacturing cost, realize the quick, safe and accurate anti-counterfeiting identification effect through the matching of the random characteristics and the mobile terminal and the server, effectively increase the anti-counterfeiting capacity through the physical visual color change, and is suitable for large-scale low-cost printing.

It was shown by many experimental data that when the UV ink of the color permeable layer was irradiated by UV curing to have a curing degree of 60%, the UV ink of the texture layer was most easily obtained with the rise and the gap and did not flow.
E, curing the texture layer through UV curing irradiation;
practices and experiments show that the UV ink of the color permeable layer has the curing degree of 30-70% through UV curing irradiation, the UV curing irradiation causes different heights of the curing degree of the color permeable layer to cause different heights of the ridges and gaps of the texture layer, when the curing degree is higher, the larger the gap is, the higher the ridge is, the simpler the random features are, and when the curing degree is lower, the smaller the gap is, the lower the ridge is, and the more the random features are, the more the random features are; therefore, different degrees of solidification can be set according to actual use conditions to meet use requirements; a plurality of times of experimental data show that when the curing degree of the color permeable layer is 60% through UV curing irradiation, the heights of the bumps and the gaps are more clear under the condition that the bump heights and the gaps are moderate.

The UV shrink ink used in the color-permeable layer contains the color fibers or a certain amount of color fibers are added into the UV ink used in the texture layer, so that the finished anti-counterfeiting marker is firmer, and the raised texture of the texture layer is not easy to fall off.
The above procedure has also found the following unexpected effects:
in actual operation, a transparent color-permeable layer is printed on a cured substrate layer by using transparent UV (ultraviolet) shrinkable ink, and the UV shrinkable ink used for the color-permeable layer contains color fibers, namely the color fibers are immersed in the UV shrinkable ink used for the color-permeable layer before printing; experiments show that after the texture layer is printed, the raised texture is clearer and more random, and the anti-counterfeiting performance is obviously improved.
In practice, a certain amount of color fibers can be added into the UV ink used on the texture layer, namely, the color fibers are immersed into the UV shrink ink used on the texture layer before printing; experiments show that after the texture layer is printed, the raised texture is clearer and more random, and the anti-counterfeiting performance of the texture layer is also obviously improved.
