[0051] Please refer to Figure 1 to Figure 4 ,in figure 1 It is a schematic diagram of the first embodiment of the random texture anti-counterfeiting label structure of the present invention, figure 2 It is a structural schematic view (top view) viewed from top to bottom of the first embodiment, image 3 It is an enlarged schematic diagram of the random texture layer in the first embodiment, Figure 4 It is a schematic perspective view of the random texture layer in the first embodiment. As shown in the figure, the random texture anti-counterfeiting mark structure of the present invention mainly includes: a substrate 1; a random texture layer 4, which is arranged on the substrate 1, and the random texture layer includes a plurality of random The distributing texture fiber body 41, the end surface of the texture fiber body 41 is a chamfered surface.
[0052] In addition, the anti-counterfeiting label structure of the present invention may further include a coding layer 3, w...

[0060] Please refer to Figure 5 and Image 6 ,in Figure 5 It is a schematic diagram of the random texture layer of the second embodiment of the random texture anti-counterfeiting label structure of the present invention, Image 6 It is a schematic perspective view of the random texture layer in the second embodiment. As shown in the figure, the difference between the anti-counterfeiting mark structure in this embodiment and the above-mentioned first embodiment is that a pattern layer 5 is also provided on the random texture layer 4, and the pattern layer 5 can generally be a printed pattern layer, that is to say, a layer of ink is printed on the top of the random texture layer 4, that is, an ink layer is printed on the top of each textured fiber body 41, and the printed ink layer follows the pattern of the textured fiber body 41. The random distribution shows a random pattern, and the random pattern is used for image acquisition and image comparison in the subsequent anti-...

[0063] Please refer to Figure 7 and Figure 8 ,in Figure 7 The enlarged schematic diagram of the printing pattern layer of the third embodiment of the random texture anti-counterfeiting label structure of the present invention, Figure 8It is an enlarged schematic diagram of the random texture layer experiment photo of the third embodiment. As shown in the figure, the difference between the anti-counterfeiting label structure in this embodiment and the second embodiment above is that the printed pattern of the pattern layer 5 itself in the second embodiment above is Regular pattern, such as grid pattern with fixed size, slash pattern with fixed interval, etc., that is to say, the pattern engraved on the gravure printing roller is a regular pattern. If it is printed on a flat white paper, it will present a regular pattern. pattern; and in the present embodiment, the printing pattern of pattern layer 5 itself is an irregular pattern (random pattern), such as a corrugated pat...
