Preparation method of dual-layer holographic anti-counterfeiting film, product with dual-layer holographic anti-counterfeiting film, and recognition method

Abstract

The invention relates to the holographic anti-counterfeiting printing industry, and particularly relates to a preparation method of a dual-layer holographic anti-counterfeiting film, a product with a dual-layer holographic anti-counterfeiting film, and a recognition method. Ink is partially printed between a laser information layer and an aluminum coated layer, and a random holographic information material is partially coated for the second time so as to form dual-layer holography, so that a product with the dual-layer holographic membrane is prepared, and the dual-layer holography of a full-edition secondary coating random holographic information material also can be prepared; a holographic information material in the partial holographic information material layer is manually stripped away from a product main body in recognition by recognizers so as to form an individual anti-counterfeiting holographic information material; the recognizers can check the true or false of the product in an experiencing mode; a traditional anti-counterfeiting method is combined with two-dimensional codes; the conversion of the anti-counterfeiting mode provides a great amount of product information; multiple unique anti-counterfeiting methods, the two-dimensional codes and random spray color films are adopted to form multiple unique patterns, and the anti-counterfeiting uniqueness requirement is met; the recognition method is a novel anti-counterfeiting recognition mode, expands the anti-counterfeiting data information amount greatly, is convenient to recognize, and improves the laser anti-counterfeiting identification efficiency.

Description

technical field [0001] The invention relates to a holographic anti-counterfeiting printing industry, in particular to a production method and product and identification method of a double-layer holographic anti-counterfeiting film. Background technique [0002] China's packaging and printing industry is developing rapidly, and the use of laser anti-counterfeiting technology and laser patterns is becoming more and more popular. With the popularization of laser patterns, the general laser anti-counterfeiting function is weakened; the method of laser film hot stamping and transfer is the current packaging The industry is very important and the most commonly used method. Its main material is anodized aluminum film. Anodized aluminum film is usually manufactured in a layered structure. On the PET base film layer, there are separation layer, imaging layer, laser information layer, and aluminized layer. , Adhesive layer, after hot stamping or transfer and peeling off the PET base f...

[0002] China's packaging and printing industry is developing rapidly, and the use of laser anti-counterfeiting technology and laser patterns is becoming more and more popular. With the popularization of laser patterns, the general laser anti-counterfeiting function is weakened; the method of laser film hot stamping and transfer is the current packaging The industry is very important and the most commonly used method. Its main material is anodized aluminum film. Anodized aluminum film is usually manufactured in a layered structure. On the PET base film layer, there are separation layer, imaging layer, laser information layer, and aluminized layer. , Adhesive layer, after hot stamping or transfer and peeling off the PET base film layer, a beautiful laser anti-counterfeiting pattern is produced, but it is difficult for ordinary people to have professional identification capabilities. Due to the popularity of laser films, ordinary people are accustomed to it, and no one goes to distinguish the real one carefully. Moreover, it is difficult to identify the authenticity in depth. Ordinary people will not recognize it in depth without a simple method. Therefore, ordinary people will give up identification because it is inconvenient to identify. How to design a laser anti-counterfeiting image with professional level How to combine various holographic anti-counterfeiting methods more effectively to become a holographic anti-counterfeiting method that not only has professional level anti-counterfeiting but also is convenient for ordinary people to identify , so that the product becomes the only genuine product, the anti-counterfeiting function is fully exerted, the uniqueness of fidelity and anti-counterfeiting is truly achieved, and at the same time, more and more complex data information and pattern information are conveniently recorded, making holographic anti-counterfeiting better for the anti-counterfeiting industry Service is an urgent problem for technicians in this industry to solve
