Description

Random net anti-fake printing material and printed matter thereof

Technical Field

The application belongs to the technical field of anti-counterfeiting, and particularly relates to an improved application technology of a Chinese patent 'structural texture anti-counterfeiting method (CN 1074563C)'.

Background

The inventor of the present application originally invented "structural texture anti-counterfeiting method (CN 1074563C)" in 1998, which belongs to the information inspection type anti-counterfeiting technology. It has acquired international patents such as chinese invention patent, US invention patent (US6623041), russian invention patent (2202127), korean invention patent (0419436), vietnam invention patent (3347), etc. The material with clear random structure texture is selected to manufacture the structure texture anti-counterfeiting marker (CN 2365711Y); and printing an identification code with uniqueness; the random structure texture on the 'structure texture anti-counterfeiting marker (CN 2365711Y)' is scanned and collected to be used as anti-counterfeiting characteristic information, namely a basis for identifying authenticity, and is combined with the identification code to be recorded and stored in a computer anti-counterfeiting query system database accessed to a telephone network or/and the Internet; the public can inquire and verify whether the random structure texture on the structure texture anti-counterfeiting marker conforms to the anti-counterfeiting characteristic information in the database through the identification code through communication tools such as a telephone, a mobile phone short message, a mobile phone multimedia message, a WeChat, a fax, a computer on the Internet and the like, thereby verifying the authenticity. The patent 'grafting the ancient tiger-sign anti-counterfeiting principle with the modern communication technology and the computer technology', creating a new anti-counterfeiting field, and being evaluated as an anti-counterfeiting technical product which is 'originated in the world, advanced in the world, extremely difficult to forge, easy to identify and effective for a long time' by 'national anti-counterfeiting office' and national anti-counterfeiting industry association and organized national level evaluation and identification. And honor the first-class prize of the anti-counterfeiting science and technology of the third China Association for anti-counterfeiting industry. After more than twenty years of popularization, the anti-counterfeiting paper becomes the leading technical product in the domestic anti-counterfeiting market. The anti-counterfeiting technology has wide application, and is recognized as the anti-counterfeiting technology of the second generation information inquiry in China in the industry. Because the identification code and the anti-counterfeiting characteristic information are clear, the anti-counterfeiting product can be purchased after being checked, so that the inquiry rate is high, the anti-counterfeiting strength is strong, and the anti-counterfeiting effect is good.

In the above "structural texture anti-counterfeiting method (CN 1074563C)", individual elements such as randomly distributed fibers, chips, irregular particles, bubbles, and impurities are used to form texture. For a long time, there has been a difficult application: in order to identify fake textures copied, a user needs to continuously publicize and warn the public that fibers are not printed ink marks, can be adjusted out by using a needle, and gives a needle to take a test (the details can be checked in hundred degrees 2018 edition of 'Mofu brand-new packaging certified product identification guide video'). Since 99.9% of consumers do not have sharp tools such as needles at hand during shopping, counterfeit goods using counterfeit-grain anti-counterfeit prints copied by copying are mistakenly purchased by consumers because they cannot be checked by needles.

In order to conveniently discriminate true and false textures by the public by hands, improve the anti-counterfeiting effect of a 'structural texture anti-counterfeiting method' and overcome the difficulty of disturbing texture anti-counterfeiting application, the inventor applies for a 'hand-tearing texture anti-counterfeiting method and a product and a material thereof (patent grant publication No. CN 109215493B)'. The random structure texture is made into a flat texture string, the characteristic information of the flat texture string is collected and stored in an anti-counterfeiting checking system database accessed to the Internet as a texture information file, so that the public can check the authenticity. The method overcomes the defect of selecting fibers (textures), achieves the purpose of manually detecting the textures, can be convenient for the public to manually discriminate true and false textures, and avoids the application trouble of selecting the textures for anti-counterfeiting. There is still a potential risk of 3D printing forgery and the disadvantage of inconvenient hand tearing to check the texture.

How to increase the difficulty of copying and counterfeiting the anti-counterfeiting marker, facilitate the bare-handed check of the texture of the public, prevent recycling and counterfeiting is always an urgent technical problem to be solved.

Preferably, the random net anti-counterfeiting printing material is characterized in that: the back of the substrate layer sequentially comprises a release agent layer, a disordered net layer, an opaque substrate layer or/and a non-dry glue layer and a release paper layer.

Preferably, the random net anti-counterfeiting printing material is characterized in that: the disordered net layer is woven by fancy yarns; preferably, the fabric is made of elastic yarn which can stretch 50-800% (for example, 5-75D).

The technical scheme of the random net anti-counterfeiting printed matter is as follows.

A random net anti-counterfeiting printed matter comprises a random structure texture layer; the random structure texture characteristic information is used as a texture information file and is stored in an anti-counterfeiting checking system database accessed to the Internet for the public to check the authenticity; the method is characterized in that: the random net anti-counterfeiting printing material is printed, and random patterns of the random net layer are used as texture information files (stored in an anti-counterfeiting checking system database accessed to the Internet for the public to check the authenticity).

The random net fabric is irregular macroporous net cloth, cannot be used as a printing material, is commonly used for wedding dresses and stage clothes, and is not repeated.

Compared with the prior art, the application can produce the following beneficial technical effects.

Firstly, 3D printing cannot be performed for counterfeiting: test experiments show that the conventional 3D printer cannot print a disordered net layer which can simulate a part of line segments to be shifted, and particularly cannot print an elastic wire which can be stretched by 50-800%. This is because: the production process of elastic filament includes the first melting and polyaddition of polyether glycol PTMG and diisocyanate MDI as main material to form prepolymer, the subsequent mixing and dissolving of the prepolymer in DMAC solvent, adding diamine for chain extending reaction to form block copolymer solution, mixing, filtering, defoaming and other steps to produce spinning dope with homogeneous performance, and the subsequent quantitative and homogeneous pressing with metering pump to form spinning head. Under the action of pressure, the spinning solution is extruded from the capillary holes of the spinneret plate to form a thin stream of filaments, and the thin stream enters the shaft. The channel is filled with hot nitrogen, so that the solvent in the strand flow is quickly volatilized and taken away by air, the concentration of the strand flow is continuously increased until the strand flow is solidified, meanwhile, the strand flow is repeatedly stretched and thinned (the strand flow needs to be repeatedly stretched and thinned like Lanzhou stretched noodles), and finally, the strand flow is formed by air false twisting, oiling and winding. The current 3D printer cannot print and imitate the complex elastic wire manufacturing process, so printing and counterfeiting cannot be carried out. In other words, the 3D printer prints the counterfeit messy net, which is forged, the elastic thread of which is not repeatedly drawn, has no strong elasticity and cannot be stretched, and is not as stiff as the noodles extruded by the noodle press.

Secondly, the public only needs to pinch a section of yarn on the anti-counterfeiting printed matter of the disordered net, slightly pulls, and checks whether the yarn can be stretched, so that the authenticity of the random pattern (namely the texture characteristic) of the disordered net layer can be checked, and the method is simple, convenient and interesting.
