Background
The legal rights of product producers and users are seriously damaged by counterfeit and imitated products, and along with the rapid development of economy, the products on the market are more abundant and various, and the requirements for distinguishing authenticity and tracing production links are stronger.
At present, in links such as production, transportation, storage, sales, use, traceability, anti-counterfeiting of products, texts, bar codes and two-dimensional codes containing product information or numbers are widely used, and the method has the advantages of being capable of being read by naked eyes or machines, easy to integrate and the like, but texts, bar codes, two-dimensional codes and the like are easy to copy directly, the imitation threshold is low, and the anti-counterfeiting capacity of the method is to be enhanced.
Disclosure of Invention
An object of embodiments of the present invention is a customizable security element and security product. The inventor finds that in various optical anti-counterfeiting technologies, anti-counterfeiting effects formed by microstructures, such as diffraction, interference, reflection, refraction, sampling and the like, are widely applied because of high brightness and obvious dynamic effect, and authenticity can be distinguished without direct human eye observation by means of instruments. However, the plate making cost of the microstructure is high, a large amount of replication and spreading are needed, and the customization is difficult.
For example, patent document CN103279731a, which uses random image details generated when printing two-dimensional codes as an anti-counterfeiting feature, performs anti-counterfeiting by comparing the obtained data information to be verified with corresponding anti-counterfeiting data information in a database.
As in patent document CN103465606a, the temperature-changing material is added to the printing of the two-dimensional code, the temperature change can be used to correspond to the color change of the two-dimensional code label to perform anti-counterfeiting, and at normal temperature, the two-dimensional code is colorless, and after heating, the two-dimensional code can be scanned and decrypted, so that the anti-counterfeiting effect of the anti-counterfeiting label is further improved.
As in patent document CN106157055A, the anti-counterfeit label matches the bar code or two-dimensional code information on the anti-counterfeit label scanned by the mobile phone with the magnetic information of the magnetic functional layer of the anti-counterfeit label sensed by the mobile phone, so as to verify the result and feed back the product tracing information.
The anti-counterfeiting element of the invention skillfully utilizes the microstructure to realize directional shielding, the same batch of anti-counterfeiting elements use the same microstructure template, and the manufactured microstructure is used for directional shielding of customizable graphics and texts, so that the customizable graphics and texts have optically variable anti-counterfeiting characteristics, and the anti-counterfeiting element has the advantages of customization, strong anti-counterfeiting capability, low cost and anti-counterfeiting.
The anti-counterfeiting element has the advantage of customization, the image-text layers can be realized by variable printing modes such as code spraying printing, and each anti-counterfeiting element can be provided with different image-text layers, for example, two-dimensional codes are used as readable elements, the image text of each anti-counterfeiting element is provided with a unique two-dimensional code, and the two-dimensional code can be scanned to obtain the traceability information of the anti-counterfeiting element and corresponding products thereof, so that the function of one object and one code is realized.
The anti-counterfeiting element has the advantage of strong anti-counterfeiting capability, the appearance of the anti-counterfeiting element is changed along with the change of the observation positions, the reproduced images displayed at different observation positions are different, the image-text layer which is not shielded can be observed only at part of the observation positions, and the authenticity of the anti-counterfeiting element, the two-dimensional code and other readable elements can be distinguished by direct observation of human eyes.
The anti-counterfeiting element has the advantage of strong anti-counterfeiting capability, and is also embodied in forcing a user to distinguish anti-counterfeiting characteristics. Many security elements have good security capabilities, and the security effect of the security element is greatly compromised because the user does not discern the security features. The anti-counterfeiting element has the optically variable anti-counterfeiting characteristic, only part of the observation positions can observe the image-text layer which is not shielded and the readable element in the image-text layer, when a user identifies the readable element, the user needs to find the observation position which is not shielded by the readable element, and the user can identify the readable element at the observation position, so that the process of identifying the readable element by the user is a process of identifying whether the anti-counterfeiting element has the optically variable anti-counterfeiting characteristic.
The anti-counterfeiting element has the advantage of low cost, the customization of the image-text layer does not involve the plate making of the microstructure, the anti-counterfeiting element with different image-text layers uses the same microstructure original edition, a large number of anti-counterfeiting elements can be copied by one-time plate making, and the plate making cost is reduced. The resolution ratio required by the micro mask and the shielding image and text is extremely high and cannot be realized by using a conventional printing process, the micro mask is realized by using a micro structure, and different appearances such as transparency, white, black, color and the like can be formed by different micro structures through one-time micro structure copying and later simple processing, and compared with methods such as laser etching and the like, the micro mask has the advantages of simple process and low cost.
The anti-counterfeiting element has the advantage of anti-counterfeiting, the image-text layer is arranged below the shielding layer and is not directly exposed outside, the image-text layer and the shielding layer are prevented from being separated, and a counterfeiter cannot tamper with the image-text layer under the condition of not damaging the shielding layer. Tampering with the image-text layer tends to destroy the shielding layer and the corresponding optical anti-counterfeiting effect, and a user can easily identify whether the anti-counterfeiting element is altered or not through observation by eyes.

The micro mask includes a light transmitting region and a light non-transmitting region. The opaque region comprises shielding graphics and texts, and the shielding graphics and texts comprise at least one of patterns, characters, bar codes, two-dimensional codes and readable elements.
