Problems solved by technology

In the existing pattern anti-counterfeiting technology research, holographic anti-counterfeiting is gradually developing in the direction of large viewing angle, multiple transformations, and strong three-dimensional effect. The anti-counterfeiting effect is good, but the development cycle is relatively long, and low-level holographic technology is easy to be imitated; The anti-counterfeiting pattern produced by ink anti-counterfeiting is easy to distinguish and analyze, but the difficulty of counterfeiting is mainly limited to the raw materials and production process. Counterfeiters may obtain raw materials and production p

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The invention utilizes the illumination model of the three-dimensional object to realize the concealment, and the hidden pattern gradually becomes clearly visible with the change of vision. The three-dimensional three-dimensional model has a total of six viewing angles. Except for the back as the base plate, there are five viewing angles: the front, up, down, left, and right. For double recessiveness, two of the angles can be used. For the convenience of introducing the principle, the double Recession is an example to illustrate, and the model setting considers using the front and left and right sides to realize recessiveness.

[0029] Based on the above considerat...

Abstract

The invention discloses a three-dimensional carrier with anti-counterfeiting performance, which comprises a plurality of same three-dimensional unit blocks arranged regularly at equal intervals, and anti-counterfeiting information arranged on the inclined lateral surfaces of the three-dimensional unit blocks, wherein the three-dimensional unit blocks have symmetrical structures provided with mutually parallel upper and lower surfaces and a plurality of inclined lateral surfaces positioned between the upper and lower surfaces, and the inclined lateral surfaces printed with the anti-counterfeiting information are designed as lateral surfaces vertical to the lower surfaces. The provided three-dimensional carrier with anti-counterfeiting performance has the advantages of good anti-counterfeiting effect, easy identification and difficult counterfeiting.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a three-dimensional carrier with anti-counterfeiting performance and a hidden anti-counterfeiting technology of a three-dimensional solid model. Background technique [0002] With the rapid development of the socialist market economy, people's material living standards have been greatly improved. However, due to people's awareness, consumption levels, and criminals driven by interests, counterfeiting and sales activities exist in almost all areas of our country, and this kind of market economy competition is becoming more and more intense. Counterfeiting has become one of the fastest-growing economic crimes in the world today, and it has brought great harm to legitimate business and employment activities, public health and health and safety order. Counterfeiters confuse the authenticity of goods by forging documents, products and their outer packaging, and even forging "anti-c...
