Problems solved by technology

Public anti-counterfeiting must be widely publicized in the society and taught to the public the knowledge and methods of identification. At the same time, it must be simple and easy to implement, so as to mobilize the masses to curb the occurrence of counterfeiting. However, the shortcomings of public anti-counterfeiting are also obvious, that is, : Poor confidentiality and low anti-counterfeiting strength. When publicizing the characteristics of anti-counterfeiting technology to the general public, it also means exposing the characteristics of anti-counterfeiting technology to counterfeiters. Therefore, in some specific occasions, public anti-counterfeiting should be combined with professional anti-counterfeiting

Embodiment

[0043] refer to figure 1 The technical flow chart of the water explicit invisible anti-counterfeiting product is completed through the following process:

[0044] 1. Select flexible film: film material: polyester plastic;

[0045] 2. Coating separation layer: separation layer material: silicone oil with a thickness of 200 nanometers;

[0046] 3. Coating multi-layer interference film group: according to the thickness and materials of each layer of interference film calculated by the computer, use physical vapor deposition methods such as vacuum evaporation to coat a multi-layer interference film on the flexible film bottom. The use of the interference film The materials are zirconium dioxide and silicon dioxide, and the interference film is four layers; respectively, silicon dioxide (sio 2 ) layer 400 nm; zirconium dioxide (z r o 2 ) layer 310 nm; silicon dioxide (sio 2 ) layer 400 nm; zirconium dioxide (z r o 2 ) layer 310 nm;

[0047] 4. Stripping: peel off the coated...

Abstract

The water display type hidden anti-fake method includes computerized design of multilayer film, coating the multilayer film, separating the multilayer film, crushing the multilayer film, mixing with print ink, printing and other steps. The present invention features the combination between the multilayer color-changing film technology and the 'water film' technology to reach the effect of dropping one drop of water to some specific area of the anti-fake product to display specific anti-fake pattern. The pattern will disappear after the water evaporates and displays color change with the altering viewing angle. The present invention has both public anti-fake function and expert anti-fake function.

Description

technical field [0001] The invention relates to the water explicit anti-counterfeiting technology, in particular to the water explicit invisible anti-counterfeiting technology of the colorless ink based on the multilayer optical film. Background technique [0002] Modern anti-counterfeiting technologies are mainly divided into two categories: [0003] The first is public anti-counterfeiting, the so-called obvious anti-counterfeiting, which is characterized by the design of signs that are easily recognizable by the public on prominent parts of the product, and the authenticity can be distinguished with the naked eye, such as various anti-counterfeiting trademarks, logos, watermarks on banknotes, security lines, Laser holographic trademarks and logos; thermochromic and photochromic anti-counterfeiting marks, etc. Public anti-counterfeiting must be widely publicized in the society and taught to the public the knowledge and methods of identification. At the same time, it must b...
