Holographic color separation variable digital anti-counterfeiting mark

Abstract

The invention discloses a holographic color separation variable digital anti-counterfeiting mark, which comprises a transparent base material layer, a laser layer, a color layer and an adhesive sticker layer which are sequentially bonded from top to bottom, wherein the color layer comprises a first color layer and a second color layer which are arranged from top to bottom, are mutually bonded and have different colors, the transparent adhesive sticker layer is arranged under the second color layer, variable digits produced randomly by a system are respectively embedded in the first color layer and the second color layer, and the digits on the first color layer and the second color layer are mutually overlapped or mutually combined to display complete variable digits. The colors of the variable digits are two or more different colors, the variable digits can be separated and can also be overlapped, but are different in colors, the manufacturing difficulty is very high, and the variable digits are difficult to copy.

Description

Technical field: [0001] The invention relates to a two-dimensional code mark, in particular to a two-dimensional code mark with a holographic effect and two or more colors. Background technique: [0002] After nearly 30 years of development, laser holographic technology has increasingly shown its limitations. On the one hand, it can be replicated in large quantities, making the cost lower and lower. disturb the market. [0003] On the other hand, the logo with variable numbers is mainly formed by a single inkjet or laser firing. Although it has a certain improvement compared with ordinary logos, it can still be copied in large quantities. Therefore, it is necessary to have a more difficult production method. Anti-counterfeiting marks are used to fill in market vacancies and set a higher threshold for counterfeiters. Contents of the invention [0004] The purpose of the present invention is to provide a color-separation holographic variable digital anti-counterfeiting mar...
