And drying the anti-counterfeiting label main body, scanning a code under a multifunctional ultraviolet analyzer for inspection, selectively adding a pasting film layer, and finally vacuumizing and sealing for packaging to obtain the anti-counterfeiting label based on the combination of the novel room-temperature phosphorescent anti-counterfeiting material and the digital anti-counterfeiting.
(3) Application of anti-counterfeit label
The application condition is as follows: the novel room-temperature phosphorescent anti-counterfeiting material replaces printing ink, anti-counterfeiting codes and patterns are combined on a base material to form a label main body by using a water-based printing and intaglio filling mode while high optical encryption is realized, the label main body is isolated from the external environment through a protective film, then in the using process, after an ultraviolet lamp is excited, a visible trademark and codes are formed on an anti-counterfeiting information layer, a mobile phone scans a two-dimensional code, and a product detail page is successfully jumped to, so that multiple anti-counterfeiting and multi-layer anti-counterfeiting are realized; after the anti-counterfeiting information layer is excited by white light, the product mark can be seen by naked eyes, so that preliminary anti-counterfeiting is realized while the use is convenient; after the anti-counterfeiting mark layer is irradiated by a specific light source, phosphorescence with a certain color can be seen by naked eyes, the pattern is clear after the light-emitting time is long, and further anti-counterfeiting is realized.
The working principle is as follows: the invention relates to a method for printing product information, enterprise commodity introduction websites and anti-counterfeiting IDs (identification) into anti-counterfeiting code patterns by using common ink, wherein the ink is replaced by a novel room-temperature phosphorescent anti-counterfeiting material, the anti-counterfeiting codes and the patterns are combined on a base material to form a label main body while high optical encryption is realized, the label main body is isolated from the external environment by a protective film by using a water-based printing and intaglio filling mode, and then in the application example process, as shown in figure 6, the anti-counterfeiting two-dimensional codes on jewelry certificates can be successfully skipped to a detection center page after being excited and scanned by an ultraviolet lamp.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
