Variable local holographic intelligent anti-counterfeiting mark and preparation method thereof

Abstract

The invention relates to an anti-counterfeiting mark, in particular to a variable local holographic intelligent anti-counterfeiting mark and a preparation method thereof. The mark comprises a plasticfilm layer, a permanent molding information layer, a positioning molding layer, a resin layer, a local printing layer, a color layer and an adhesive layer, wherein the plastic film layer, the permanent molding information layer, the positioning molding layer, the resin layer, the local printing layer, the color layer and the adhesive layer are arranged in sequence from top to bottom, a local hollow printing layer and a local aluminum coating layer are arranged between the positioning molding layer and the resin layer, the local hollow printing layer and the local aluminum coating layer respectively contain part of variable information which form integrated variable information after being combined, the variable information contains a two-dimensional code, an invisible ink layer is arrangedbelow the corresponding local aluminum coating layer, the local hollow printing layer corresponds to the local printing layer in positions, and the information of the local printing layer correspondsto the variable information. The mark has the advantages of difficulty in counterfeiting, simplicity in identification and good anti-counterfeiting effect, and secondary use can be effectively prevented. The invention further provides the preparation method of the variable local holographic intelligent anti-counterfeiting mark.

Description

technical field [0001] The invention relates to an anti-counterfeit mark, in particular to a variable local holographic intelligent anti-counterfeit mark and a preparation method thereof. Background technique [0002] Anodized aluminum, also known as hot stamping paper, is a hot stamping material composed of polyester film (PET) and a multi-layer chemical coating coated on its surface. According to the hot stamping variety, it can be divided into three categories: ordinary anodized aluminum, Hologram anodized aluminum, holographic positioning anodized aluminum. The production process of ordinary anodized aluminum is simple, the color material layer is single color, no molded layer, and the hot stamping pattern is single, and it is mainly used in products that do not require high surface decoration effects; hologram anodized aluminum is molded on the colored layer. Form a variety of laser holographic patterns, which are widely used in the commodity packaging and printing ind...

Problems solved by technology

[0003] However, the information of the current holographic anti-counterfeiting label is exactly the same and immutable. The base material is coated with a molded information layer, and then molded, washed with aluminum ink, plated with aluminum, and washed with aluminum. Aluminum is fixed, and it is impossible to achieve variable holographic anodized aluminum

It is not convenient for product logistics management and anti-counterfeiting query digital management

[0004] In addition, the logo holographic pattern and printed pattern on the market are relatively independent, which is easy to be faked. The holographic pattern and printed pattern are not integrated, and the design sense is poor.
