Description

Invisible and visual machine-readable anti-counterfeiting method, the obtained mark and the preparation method of the mark

technical field

The invention relates to an invisible and visual machine-readable anti-counterfeiting method, the obtained mark and a preparation method of the mark, belonging to the field of anti-counterfeiting marks.

Background technique

With the development of science and technology, the improvement of people's counterfeiting ability cannot be ignored. In order to prevent products from being counterfeited, anti-counterfeiting methods are increasingly diversified. Commodity manufacturers in order to prevent their products from being counterfeited, causing bad influence on the company or infringement of interests, most of them use anti-counterfeiting marks to anti-counterfeit their products. The production cost also increases accordingly.

Due to the uncertainty of random texture features, random texture anti-counterfeiting technology can make the anti-counterfeiting features of each logo unique. Therefore, since its appearance, it has been widely used, and its anti-counterfeiting strength has been further improved in the process of use. . Chinese patents CN 107154213 A and CN 108682288 A respectively disclose an intelligent random feature recognition anti-counterfeiting label and its preparation method, and an anti-counterfeiting label and its preparation method for uncovering multiple verification random features, with simple identification and good anti-counterfeiting effect.

But there is a problem with the above identification:

The random texture features of the logo (anti-counterfeiting particles, anti-counterfeiting metal sheets, etc.) are collected by taking pictures or scanning with a high-power lens, and then printed on the logo by printing, which can be similar to the visual effect of the above logo. If consumers Without careful comparison, it is difficult to find the difference, which can mislead some consumers and bring certain economic losses to consumers.

Contents of the invention

In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide an invisible and visual machine-readable anti-counterfeiting method with high anti-counterfeiting strength and not easy to be copied; method.

The invisible and visualized machine-readable anti-counterfeiting method of the present invention includes invisible machine-readable anti-counterfeiting information, and the invisible machine-readable anti-counterfeiting information is obtained by printing the machine-readable anti-counterfeiting ink mixed with ordinary ink, and the invisible machine-readable anti-counterfeiting information is printed with a magnifying glass Randomly distributed particles of different sizes can be seen under the excitation light equipment;

Collect the random variable information of the above-mentioned granular points, associate it with other variable information, and perform anti-counterfeiting through the association relationship.

in:

The dosage of the machine-readable anti-counterfeiting ink is 5-20% of the mass of ordinary ink. For example, it can be 5%, 10%, 15%, 20%, etc., within this range, as the proportion of the invisible luminescent substance increases, more particles are printed. When the invisible luminescent substance is less than 5%, there are few particles, and there is a phenomenon that the invisible luminescent substance cannot be printed; when the invisible luminescent substance is more than 20%, the entire invisible luminescent substance area will display bright colors as a whole, and the random distribution of individual particles cannot be observed, and the anti-counterfeiting strength is reduced. , easily imitated.

The machine-readable anti-counterfeiting ink contains invisible luminescent substances, and the particle diameter of the invisible luminescent substances is 5-20 μm. When the particle size is less than 5 μm, the fine luminescent substances are not easy to observe, and the random distribution cannot be observed; when it is greater than 20 μm, the particle size is too large, which makes it impossible to print, especially flexographic printing.

Preferably, the machine-readable anti-counterfeiting ink is a commercially available ink from Zhongchao Ink Co., Ltd. - Galaxy Jingxing 01 ink. The ink appears bright under blue excitation light and is invisible in natural light.
