Problems solved by technology

[0004] At present, the invisible pattern anti-counterfeiting techniques commonly used at home and abroad include laser anti-counterfeiting, laser anti-counterfeiting and pattern anti-counterfeiting. The cost of printing also brings certain difficulties in the printing process, and only need to buy this software to imitate the production, and it cannot play the role of real anti-counterfeiting

Embodiment 1

[0038] The specific production process of the multi-level implicit image anti-counterfeiting process of the present invention is:

[0039] 1. Use Adobe's vector graphic design software (CoreLDRAW image, graphic design software)

[0040] (1) First make a group of invisible characters, then use complex superimposed lines to make textures, and then put the created textures into the previously designed characters group by group, so that the effect of invisible characters will come out.

[0041] (2) Make a solid bottom line pattern with the same method as above, and then combine two groups of designed line patterns to form a multi-level hidden image anti-counterfeiting.

[0042] (3) The anti-counterfeiting texture of the multi-level hidden image is made into a positive film through the film company.

[0043] 2. The production process of the embossed plate:

[0044] (1) Polish the front and back of the 1cr18Ni9Pi (or 0cr18Ni9) stainless steel plate with sandpaper of more than 1500...

Embodiment 2

[0058] First use graphics processing software to make the implicit graphic information into light patterns, and then output the negative film, and use the matching sensory glue to match the negative film and make the positive picture of the anti-counterfeit identifier corresponding to the negative film, and implement the other processes in the same way example 1.

Abstract

The invention relates to a multilevel implication graph anti-counterfeiting technology. The anti-counterfeiting technology is characterized by firstly making information of an implication graph into light ripple by a graphic processing software and outputting a positive film, making a positive film picture or a negative film picture into a stainless steel embossed plate by etching method, and carrying out localized embossing by embossing equipment with a heating and pressurizing device. The multilevel implication graph anti-counterfeiting process is mainly realized by the optical refraction principle, and is completed during plate making and realized during embossing without changing the original printing method and the original printing flow. The multilevel implication graph anti-counterfeiting process is characterized by high safety and reliability, easy identification and recognition, difficulty in counterfeiting, and easy operable detection, high anti-counterfeit performance, strong adaptability and the like, and has low design cost and low manufacturing lost.

Description

technical field [0001] The invention relates to an anti-counterfeiting technology in the packaging printing technology, in particular to a multi-level implicit image anti-counterfeiting technology. Background technique [0002] In the field of packaging printing, anti-counterfeiting printing plays a vital role. If general products need a prominent product logo, then many high-end and brand-name products have to need a complete anti-counterfeiting system. This is the need of manufacturers and also the needs of consumers. Therefore, anti-counterfeiting printing is widely used in the printing of packaging and decoration products, and with the continuous improvement of people's brand awareness and the strengthening of intellectual property protection, anti-counterfeiting printing will have greater market prospects. [0003] Invisible pattern anti-counterfeiting subject is a frontier and hot field of scientific research at home and abroad. It is the latest information hiding te...
