Composite multifunctional anti-counterfeiting mark with combination of two-dimensional code and optically variable image

Abstract

The invention provides a composite multifunctional anti-counterfeiting mark with combination of a two-dimensional code and an optically variable image. In a technical means adopted by the invention, the composite multifunctional anti-counterfeiting mark with combination of the two-dimensional code and the optically variable image is provided with an optically variable image area and a two-dimensional code identification area; the optically variable image area comprises a thin film layer, a stripping layer, a mould pressing layer, an aluminium coated layer and a glue layer; the two-dimensional code identification area is integrally connected with the optically variable image area, and the position of the two-dimensional code identification area is adjusted according to pattern information to be reserved in the optically variable image area by taking the reference that anti-counterfeiting pattern information to be reserved in the optically variable image area cannot be shielded and damaged; and the two-dimensional code identification area is structurally the same with the optically variable image area and comprises a thin film layer, a stripping layer, a mould pressing layer, an aluminium coated layer and a glue layer.

Description

technical field [0001] The invention relates to the fields of anti-counterfeit marks and anti-counterfeit stamps, in particular to OVD and digital anti-counterfeit technologies. Background technique [0002] Optically variable image (OVD) is a sophisticated optical anti-counterfeiting mark, which applies complex laser diffraction technology, and when the light is projected on the surface of fine stripes, it will be transformed into a diffraction effect, which can produce depth, perspective and so on in the design. And multi-level reflection effect, easy to identify, easy to remember, easy to describe, making it stand out among many anti-counterfeiting technologies. Optically variable images are characterized by photorefraction, in which variable light incidence can cause changes in the image, from different viewing angles, showing clear image contrast, even in diffuse light or dim lighting conditions, and its structure. Can be identified, thus providing consumers with a sim...

Problems solved by technology

At present, the master generation technologies commonly used at home and abroad are mainly "two-dimensional / three-dimensional" and "digital lattice". However, the above two mastering technologies that are still effective abroad have become commodities in China. Reliability is already very low

[0004] Two-dimensional codes have the characteristics of large storage capacity, high confidentiality, high traceability, and low cost, but they do not have anti-counterfeiting functions. To apply two-dimensional codes in the field of commodity anti-counterfeiting, the first thing to do is to solve the problem of the two-dimensional code anti-counterfeiting label itself. The problem of unforgeability, that is, the anti-counterfeiting of the logo itself

[0008] The anti-counterfeiting mark disclosed in the above-mentioned patent has the following problems: when consumers use it, they can only scratch off the first layer, find the digital code, and send the digital code to the system through telephone, network, SMS, etc., and the system can only identify the authenticity of the product after feedback. False, inconvenient to use, and the anti-counterfeiting mark cannot be organically combined with the product packaging, and the consumer acceptance is not high

[0009] The Chinese utility model patent with the patent number of 02270995.9 discloses a holographic miniature printed digital two-dimensional code anti-counterfeit label, which is composed of digital code and PDF417 two-dimensional code anti-counterfeit layer, color printing machine micro-miniature anti-counterfeit composite layer, pressure-sensitive The glue layer is superimposed and compounded, and a laser holographic image is made at a local position on the digital code and PDF417 two-dimensional code anti-counterfeiting layer. The anti-counterfeiting mark adopts local holographic technology, plastic printing micro-technology, digital code technology and PDF417 two-dimensional code technology Comprehensive application forms multiple anti-counterfeiting. The anti-counterfeiting label includes digital codes and PDF417 two-dimensional codes, which are all attached by printing. The abrasion resistance is poor, and more information patterns are combined together, which is a bit complicated. Furthermore, The production of the anti-counterfeiting label involves a variety of processes and is relatively complicated. The laser holographic technology used has basically lost the anti-counterfeiting function, which will increase the production cost and is not conducive to the promotion and use of ordinary commodities.

[0010] The patent numbers are 201020102478.2, 201010101642.2, 201020115905.0, 200710173477.X, 200920060588.4 Several Chinese patents disclose different anti-counterfeiting technologies and signs involving two-dimensional codes, but the above patents have a common feature: computer-generated two-dimensional codes and other information , the code reading equipment obtains the two-dimensional code information, and after conversion, the two-dimensional code is marked on the surface of the product (the surface of the card, glass, etc.) through the high-energy laser beam through the laser marking device. It is used on products with hard surface and not easy to deform, but it cannot be implemented for many products such as paper packaging and plastic packaging products
