Description

Customizable anti-counterfeiting element and anti-counterfeiting product

Technical Field

The invention belongs to the field of anti-counterfeiting identification and anti-counterfeiting tracing marks, and particularly relates to a customizable anti-counterfeiting element and an anti-counterfeiting product.

Background

Counterfeit and imitated products seriously damage the legitimate rights and interests of product producers and users, along with the rapid development of economy, products on the market are more abundant and diversified, and the requirements for distinguishing authenticity and tracing production links are stronger.

At present, in the links of production, transportation, storage, sale, use, tracing, anti-counterfeiting and the like of products, texts, bar codes and two-dimensional codes containing product information or numbers are widely used, and have the advantages of being capable of being read by naked eyes or machines, easy to integrate and the like, but the texts, the bar codes, the two-dimensional codes and the like are easy to directly copy, the imitation threshold is low, and the anti-counterfeiting capacity is to be enhanced.

Disclosure of Invention

The embodiment of the invention aims at a customizable anti-counterfeiting element and an anti-counterfeiting product. The inventor finds that: in various optical anti-counterfeiting technologies, anti-counterfeiting effects formed by microstructures include diffraction, interference, reflection, refraction, sampling and other effects, and the effects are widely applied due to high brightness and obvious dynamic effect, and the 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 is required to reduce the finished product, and the customization is difficult.

For example, patent document CN103279731A, it uses the random image details generated when printing the two-dimensional code as the anti-counterfeiting feature part, and performs anti-counterfeiting by comparing the obtained data information to be verified with the corresponding anti-counterfeiting data information in the database.

For example, patent document CN103465606A, a temperature-variable material is added to the printing of the two-dimensional code, so that the temperature change can be used to perform anti-counterfeiting corresponding to the color change of the two-dimensional code label, and at normal temperature, the two-dimensional code is colorless, and can be scanned and decrypted after being heated, thereby further improving the anti-counterfeiting effect of the anti-counterfeiting label.

For example, in patent document CN106157055A, the anti-counterfeiting tracing identifier matches bar code or two-dimensional code information on the anti-counterfeiting tracing label scanned by using a mobile phone with magnetic information of a magnetic functional layer of the anti-counterfeiting tracing label sensed by using the mobile phone, so as to verify a result and feed back product tracing information.

The anti-counterfeiting element skillfully utilizes the microstructure to realize directional shielding, the same batch of anti-counterfeiting elements use the same microstructure template, and the manufactured microstructure directionally shields customizable images and texts, so that the customizable images and texts have the optically variable anti-counterfeiting characteristic, and the anti-counterfeiting element has the advantages of customization, strong anti-counterfeiting capability, low cost and deformation resistance.

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 the like, each anti-counterfeiting element can be provided with different image-text layers, for example, a two-dimensional code is used as a readable element, the image-text of each anti-counterfeiting element has a unique two-dimensional code, and the tracing information of the anti-counterfeiting element and corresponding products can be obtained by scanning the two-dimensional code, 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 presented at different observation positions are different, the non-shielded image-text layer can be observed only at partial observation positions, and the authenticity of the anti-counterfeiting element, the two-dimensional code and other readable elements can be identified by direct observation of human eyes.

The anti-counterfeiting element has the advantage of strong anti-counterfeiting capability, and is also reflected in forcing a user to distinguish anti-counterfeiting characteristics. Many anti-counterfeiting elements have good anti-counterfeiting capability, and the anti-counterfeiting effect of the anti-counterfeiting elements is greatly reduced because users do not distinguish anti-counterfeiting characteristics. The anti-counterfeiting element has the optically variable anti-counterfeiting characteristic, the non-shielded image-text layer and the readable elements in the image-text layer can be observed only at part of the observation positions, and when a user identifies the readable elements, the user needs to find the observation positions where the readable elements are not shielded first to identify the readable elements at the observation positions, so that the process of identifying the readable elements by the user is the process of identifying whether the anti-counterfeiting characteristic has the optically variable anti-counterfeiting characteristic.

The anti-counterfeiting element has the advantage of low cost, the customization of the image-text layers does not relate to the plate making of the microstructure, the anti-counterfeiting elements with different image-text layers use the same microstructure original plate, a large number of anti-counterfeiting elements can be copied by one plate making, and the plate making cost is reduced. The resolution required by the micro mask and the shielding graphics context is extremely high, and the micro mask and the shielding graphics context cannot be realized by using a conventional printing process.

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 without damaging the shielding layer. Tampering with the image-text layer will certainly 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 by observing with human eyes.

The shielding layer is a light field imaging system, and the first image-text layer 2 and the shielding layer 1 are prevented from being separated, so that the elements can be damaged after the separation. The thickness of the security element is not more than 5mm, preferably not more than 200um, further preferably not more than 100um.

The micro-mask includes a transparent region and an opaque 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. Taking the two-dimensional code as an example, the two-dimensional code has four fault tolerance levels of L, M, Q, and H, and the corresponding fault tolerance levels are 7%, 15%, 25%, and 30%.
