Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting labels, in particular to an anti-counterfeiting laser cat's eye paper. Background Art

[0002] Current anti-counterfeiting label technology mainly relies on printing or spraying ink on paper or other substrates to generate identification patterns. Although these patterns have different designs, they are easy to copy through modern digital printing technology, which greatly reduces the anti-counterfeiting effect. Counterfeiters can easily imitate existing anti-counterfeiting patterns, causing the problem of rampant counterfeit goods in the market. Traditional label structures usually cannot directly achieve high anti-counterfeiting through simple embossing processes, and require complex design and manufacturing processes, which undoubtedly increases the cost and technical difficulty of label production.

[0003] In view of this situation, the utility model aims to propose a new anti-counterfeiting laser cat's eye paper and a preparation method and a counterfeit identification method thereof, so as to overcome the limitations of traditional label anti-counterfeiting technology. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides an anti-counterfeiting laser cat's eye paper.

[0026] Example 1, reference Figure 1-2 The anti-counterfeiting laser cat's eye paper includes a bottom layer 1, a transition layer 2, a glue layer 3 and an embossed surface layer 4 which are compositely arranged in sequence from bottom to top. A cat's eye layer 5 is arranged on the embossed surface layer, and a plurality of photoetched patterns 6 and hot stamping patterns 10 are arranged around the cat's eye layer.

[0027] The label of the present application includes a bottom layer, a transition layer, an adhesive layer and an embossed surface layer which are compounded in sequence, and can emboss durable and effective photoetching patterns and hot stamping patterns on the label. The surface has a good metallic luster and is not easy to be imitated. It also has a simple structure, is easy to manufacture and has a low cost.

[0028] The composite structure design, which consists of a base layer, a transition layer, a glue layer and an embossed surface layer from bottom to top, enhances the overall physical properties and visual effects of the paper through the combination of different materials, making it more durable and beautiful, while also increasing the difficulty of counterfeiting.

[0029] Among them, the photoetching pattern is processed by photolithography technology, and the hot stamping pattern is processed by hot stamping technology.

[0030] Specifically, a transition layer is arranged between the bottom layer and the adhesive layer; the bottom layer is a paper layer; the embossed surface layer is a laser film; the cat's eye layer is circular and is a laser film; a printing layer 7 and a varnish film 8 are arranged on the embossed surface layer; a two-dimensional code printing area is provided on the embossed surface layer, and an anti-counterfeiting digital code 11 is arranged in the two-dimensional code printing area 9; and the transition layer is a PET film.

[0031] Among them, the embossed surface uses a laser film. This special film can present rich laser effects under light, adding a strong anti-counterfeiting element that is difficult to copy.

[0032] Among them, the cat's eye layer is designed as a circular laser film. This structure makes the product present an unpredictable three-dimensional visual effect similar to a cat's eye when observed at different angles, which greatly enhances the uniqueness of the anti-counterfeiting mark and improves the ability to identify authenticity.

[0033] A printing layer and a varnish film are set on the embossed surface, which not only allows for graphic printing to enhance information display, but the addition of the varnish film also provides additional protection and gloss, making the product surface smoother and brighter, while also helping to enhance the anti-counterfeiting function.

[0034] A QR code printing area is specially set on the embossed surface, and an anti-counterfeiting digital code is printed in this area. This design allows each laser cat's eye paper to carry unique and verifiable information. By scanning the QR code and querying the digital code, consumers and relevant institutions can quickly and accurately identify the authenticity of the product, greatly improving the anti-counterfeiting effectiveness. Moreover, when comparing with the pictures in the database, it does not only rely on the arrangement of the photolithography and hot stamping patterns for comparison, but also adds the comparison of the anti-counterfeiting digital code to improve the comparison accuracy.

[0035] The preparation method of the present application comprises the following steps:

[0036] S1: Laying a transition layer, and using a laminating machine to coat the PET film on the bottom layer to form a layer of PET film;

[0037] S2: Glue coating: using a spray device to evenly coat the DVA glue on the surface of the transition layer in step S1 to form a DVA glue layer;

[0038] S3: Laminating, laminating the laser paper on the DVA adhesive layer in step S2 through a laminating machine to form an embossed surface layer and a cat's eye layer;

[0039] S4: printing, using a printing device to print a desired pattern or color on the embossed surface layer in step S3, thereby forming a printed layer;

[0040] S5: applying varnish, using an oiling device to apply varnish on the surface of the printing layer in step S4, so that a varnish layer is formed on the surface of the printing layer;

[0041] S6: embossing, using embossing equipment to emboss the desired convex pattern on the surface of the varnish layer in step S6 to complete the preparation of the anti-counterfeiting laser cat's eye paper.

[0042] In the gluing step in S2, oil glue can also be sprayed on the surface of the transition layer, and the oil glue can be used as a substitute for the glue layer of DVA glue.

[0043] Furthermore, the gluing temperature in the gluing step in step S2 is 200-300°.

[0044] Furthermore, the coating temperature in the coating steps in step S1 and step S2 is 80-150°.

[0045] In addition, when making anti-counterfeiting laser cat's eye paper without a transition layer, directly apply glue on the base layer, and then go through lamination, printing, varnishing and embossing.

[0046] The authentication method of the present application comprises the following steps:

[0047] S1: Obtaining the QR code image data in the preset QR code printing area on the surface of the anti-counterfeiting laser cat's eye paper through the terminal device, and obtaining the photolithography pattern arrangement information and the hot stamping pattern arrangement information through the terminal device;

[0048] S2: transmitting the two-dimensional code image data, photolithography arrangement information and hot stamping arrangement information to a cloud server, and searching the cloud database for matching pre-stored two-dimensional code image information, photolithography arrangement information and hot stamping arrangement information;

[0049] S3: The cloud server compares the pre-stored QR code image information, photolithography pattern arrangement information and hot stamping pattern arrangement information with the received QR code image information, photolithography pattern arrangement information and hot stamping pattern arrangement information in real time;

[0050] S4: If the comparison results are consistent, the anti-counterfeiting laser cat's eye paper is determined to be authentic, and a verification success message is fed back to the user through the terminal device; otherwise, it is determined to be counterfeit and the user is prompted that the verification failed;

[0051] Among them, the pre-stored QR code image information contains encrypted QR code image data bound to the unique anti-counterfeiting digital code on each anti-counterfeiting laser cat's eye paper, and the cloud database is used to store the unique anti-counterfeiting identification data corresponding to each authentic laser cat's eye paper.

[0052] The above anti-counterfeiting laser cat's eye paper authentication method has the following advantages:

[0053] 1. Convenient and efficient verification process: Through simple scanning steps, users only need to use terminal devices (such as smart phones) to scan the QR code printing area to start the verification process. No complicated operations and professional knowledge are required, which greatly improves the convenience and efficiency of anti-counterfeiting verification.

[0054] 2. Cloud-based intelligent comparison: The scanned QR code data is compared in real time with the genuine data pre-stored in the cloud database, ensuring the authority and accuracy of the verification results and effectively preventing the penetration of counterfeit products.

[0055] 3. One-to-one binding anti-counterfeiting: The QR code, photolithography pattern arrangement information and hot stamping pattern arrangement information on each piece of laser cat's eye paper are bound to the specific anti-counterfeiting digital code stored in the cloud database, ensuring that each piece of paper has a unique anti-counterfeiting identity, greatly enhancing the anti-counterfeiting effect.

[0056] 4. Timely feedback of results: After receiving the verification results from the cloud server, the terminal device can immediately provide users with information feedback on success or failure of the verification, helping users to make quick judgments and ensure transaction security and consumer rights.

[0057] 5. High degree of automation: This method replaces traditional manual inspection with intelligent means, reducing the errors and time costs that may be caused by manual participation, while enhancing the response speed and consistency of the anti-counterfeiting system.

[0058] 6. Comprehensively upgrade the anti-counterfeiting system: This method combines the complex physical structure anti-counterfeiting characteristics of the laser cat's eye paper itself with modern information technology to form a double or even multiple anti-counterfeiting barrier, effectively cracking down on illegal counterfeiting and maintaining market order and brand image.

[0059] Example 2: The difference between Example 2 and Example 1 is that the transition layer of Example 2 is a varnish layer, and the corresponding S1: laying the transition layer, and using a varnish machine to coat the bottom layer to form a varnish film.

[0060] Example 3: The difference between Example 3 and Examples 1 and 2 is that the transition layer of Example 3 is an OPP film, and the corresponding step S1 is: laying the transition layer, and covering the OPP film on the bottom layer by a laminating machine to form a layer of OPP film.

[0061] In the comparison of the three embodiments, the embossing formed on the anti-counterfeiting label with the transition layer made of PET film is clearer, the surface metallic feel is stronger, and it has relatively better anti-counterfeiting effect and appearance.

[0062] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the utility model concept of the utility model is not limited to this utility model. Any modification using the utility model concept will be included in the scope of protection of this patent right.
