Composite multifunctional anti-counterfeiting mark manufactured by utilizing laser etching

Abstract

The invention provides a composite multifunctional anti-counterfeiting mark manufactured by utilizing laser etching. With respect to adopted technical means, the composite multifunctional anti-counterfeiting mark manufactured by utilizing laser etching is composed of a thin film layer, a stripping layer, a mould pressing layer, an aluminized layer and a glue layer; an optical variable image is provided with a reserved position which is added with a background pattern with the anti-counterfeiting function; the substances of the mould pressing layer and the aluminized layer in the background pattern are selectively gasified by high-energy laser to obtain an image, characters or marks which are formed by a blank position and the background pattern; consumers can easily judge the authenticity of the product by the direct visual observation by virtue of the high anti-counterfeiting performance of the optical variable image on the mark and the uniqueness of a two-dimension code and the optical variable image which are located and processed; and the invention can also provide a platform to form an interaction between the consumer and a product manufacturer by utilizing a terminal device, so that the anti-counterfeiting mark provided by the invention achieves the purposes of market popularization, market information collecting and product tracking while the information of the product is assured.

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

[0010] 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

[0011] 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 adhesive layer is superimposed and compounded, and a laser holographic pattern is made on the local position of the digital code and the PDF417 two-dimensional code anti-counterfeiting layer. The anti-counterfeiting mark adopts local holographic technology, plastic printing miniature 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.

[0012] 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
