Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-counterfeiting technology, specifically an anti-counterfeiting label with a grating-based QR code for verification. Background Technology
[0002] Currently, QR code technology is widely used for product anti-counterfeiting. Consumers scan the QR code with their mobile phones to verify the authenticity of the product. However, the QR code itself does not have anti-counterfeiting functionality; it is only used to store a link address. Counterfeiters can easily copy genuine product QR codes, making it difficult for consumers to distinguish between genuine and fake products. Therefore, developing labels with truly effective anti-counterfeiting functions is an important research direction for the anti-counterfeiting industry.
[0003] Therefore, this application provides an anti-counterfeiting label with a grating-based verification QR code to solve the problems existing in the background art. Utility Model Content
[0004] Purpose of the utility model: To provide an anti-counterfeiting label with a grating-based verification QR code. By embedding a grating structure within the QR code area, it enables both scanning of the QR code and verification of the grating information through a specific resolution chip, thereby effectively preventing counterfeiting and improving the anti-counterfeiting level.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An anti-counterfeiting label with a raster-based verification QR code includes:
[0007] The substrate layer is used to support the entire anti-counterfeiting label;
[0008] A grating layer, located above the substrate layer, includes periodically arranged grating structures embedded with preset anti-counterfeiting elements, and the grating layer covers at least a portion of the QR code area.
[0009] The QR code layer, located above the grating layer, contains a standard QR code pattern and is used to store product information and verification information.
[0010] The protective layer, located above the QR code layer, is used to protect both the QR code layer and the raster layer.
[0011] The analytical chip, used in conjunction with the anti-counterfeiting label, is used to analyze the anti-counterfeiting elements in the grating layer.
[0012] As a further improvement to the above technical solution:
[0013] The grating period of the grating layer is 10μm-50μm, and the grating depth is 2μm-10μm.
[0014] The analytical sheet has a lens or grating structure that matches the grating period of the grating layer.
[0015] The anti-counterfeiting elements are text, patterns, or special codes.
[0016] The substrate layer is made of paper, plastic film, or other suitable materials.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. High anti-counterfeiting level: The embedding of the grating structure and the use of the analytical chip make it difficult for counterfeiters to copy the anti-counterfeiting mark, effectively improving the anti-counterfeiting level.
[0019] 2. Easy to identify: Consumers can easily and quickly verify the authenticity of the anti-counterfeiting label using the analytical chip.
[0020] 3. Good compatibility: The presence of the QR code layer makes the anti-counterfeiting label compatible with existing QR code scanning devices and systems, facilitating the query and management of product information.
[0021] 4. Good concealment: Under normal visual inspection, the grating layer appears as halftone dots, making it difficult to detect its anti-counterfeiting function and providing a certain degree of concealment. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0026] Applicant's design Figure 1-2 The anti-counterfeiting label shown includes a grating-based QR code verification layer 1, a grating layer 2, a QR code layer 3, and a protective layer 4.
[0027] Substrate layer 1: PET film is selected as the substrate with a thickness of 50μm.
[0028] Grating layer 2: A periodically arranged grating structure is fabricated on a PET film using photolithography. The grating period is 25μm and the grating depth is 5μm. Anti-counterfeiting elements bearing the words "Genuine Product" are embedded in the grating structure.
[0029] QR code layer 3: A standard QR code pattern is printed on top of the lenticular layer 2 using digital printing technology. The QR code content contains product information and verification information.
[0030] Protective layer 4: A transparent UV coating with a thickness of 5μm is applied on top of the QR code layer 3 to protect the QR code layer 3 and the grating layer 2 from wear and damage.
[0031] Resolution 5: It adopts a lens structure that matches the grating period of grating layer 2. When resolution 5 observes grating layer 2 at a specific angle, the embedded "Genuine" mark can be clearly displayed.
[0032] How to use:
[0033] Consumers first use their mobile phones to scan the QR code on the anti-counterfeiting label to obtain product information and verification information.
[0034] Then, using the matching analytical chip 5, observe the grating layer 2 on the anti-counterfeiting label at a specific angle. If the embedded anti-counterfeiting elements can be clearly seen, it can be preliminarily determined that the product is genuine.
[0035] By combining the QR code scanning results and the raster analysis results, the authenticity of the product can be determined more accurately.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
