In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the present application, the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. These terms are used primarily to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to a particular orientation or to be constructed and operated in a particular orientation. Moreover, some of the above terms may be used to indicate other meanings besides the orientation or positional relationship, for example, the term "on" may also be used to indicate some kind of attachment or connection relationship in some cases. The specific meaning of these terms in this application will be understood by those of ordinary skill in the art as appropriate.
As shown in fig. 1, the laser anti-counterfeit label according to an embodiment of the present invention includes, from top to bottom, an ink layer 3, a substrate layer 4, a glue layer 5, and a release layer 6, where the ink layer 3 is printed on the surface of the substrate layer 4, and includes a two-dimensional code area and a random pattern area, and the two-dimensional code and the random pattern are used as different anti-counterfeit means and both need to be scanned and identified by a mobile phone. The color of the ink in the random pattern area is obviously different from that of the substrate layer 4, so that the random pattern formed by the part of the substrate layer 4 which is not covered by the ink is easy to identify. Since the color of the base material layer 4 itself is usually a chromatic color, it is preferable to use a black ink for the random pattern region in order to form a color difference. The viscous force between substrate layer 4 and glue layer 5 is greater than glue layer 5 and from the viscous force between type layer 6 to guarantee that substrate layer 4 and the layer combination above that closely just easily break away from type layer 6, substrate layer 4 and 3 accessible glue layers 5 firm pastes on article on its surface on the substrate layer.
Specifically, the two-dimensional code area can be formed by directly printing ink on the surface of the base material layer, or a layer of ink is printed on the base material layer as a substrate, and then the two-dimensional code area is printed on the substrate, wherein the color of the substrate and the color of the two-dimensional code should have obvious color difference. For example, the substrate is white ink and the two-dimensional code is black ink.
Generally, the laser anti-counterfeiting label also comprises graphic and text information such as logo and the like, the graphic and text information is positioned in the two-dimensional code area, and the ink is sprayed or printed on the substrate layer 4 or the ink substrate. Preferably, the laser anti-counterfeiting label further comprises a laser layer 2 which is composed of a plurality of laser particles and distributed in the area outside the random pattern area. The laser layer 2 is made of a plain laser material, and commonly comprises PET, OPP and the like. The laser layer 2 is composed of laser particles made of the materials, the shape of the laser particles can be any one or combination of a plurality of circular, triangular, rectangular, trapezoidal, polygonal or linear shapes, and the laser particles are randomly distributed on the ink layer 3 in the modes of powder scattering, spraying, silk screen printing and the like to form the laser layer 2.
Preferably, the laser anti-counterfeit label further comprises a protective layer 1, wherein the protective layer 1 is a transparent film, and common transparent films include a PET film, a PP film, a PE film, a PVC film, and the like. Protective layer 1 covers on radium-shine layer 2 and printing ink layer 3 surface, sees through transparent protective layer 1 and enables radium-shine layer 2 pattern and printing ink layer 3's picture and text easy scanning and discernment, because protective layer 1 material can be water and oil proofing again, consequently can prevent that radium-shine layer 2 and printing ink layer 3's effective information from being contaminated or blade coating. The protective layer 1 must be free of bubbles to ensure the identification accuracy and stability of the laser area. An embodiment of a label having 6 layers is shown in fig. 2.
The ink layer 3 adopts a printing mode of digital printing, carbon ribbon printing or spray printing. Because the two-dimensional code and the image-text information are printed, the ink layer 3 needs to have a certain thickness in order to guarantee a higher two-dimensional code recognition rate.
In order to observe different effects from different angles, the substrate layer 4 is usually made of laser synthetic paper, which can be printed to print ink.
The glue layer 5 can be made of water glue, oil glue, non-setting adhesive, UV glue, gloss oil and the like.
The release layer 6 is usually release paper or release film.
The schematic diagram of the laser anti-counterfeit label with the six-layer structure is shown in fig. 2.
When the label is used, the release layer 6 is torn down, the label is attached to a target object, and the label is lightly smoothed. When the counterfeit is checked, whether the particle area on the surface of the label has a three-dimensional effect is checked through touching, the black random laser pattern of the label is observed from different angles to determine that the label can present different colors, the label is scanned by using counterfeit checking software, so that the two-dimensional code, the random pattern and even the laser pattern are all positioned in the identification frame, and the software carries out internal operation according to the scanning result, compares the two-dimensional code, the random pattern and even the laser pattern with the stored data of the article and checks the authenticity of the article. Common counterfeit detection software is APP or WeChat applet.
