Three-dimensional information anti-counterfeit mark article and manufacturing method thereof

Abstract

The invention provides a three-dimensional information anti-fake marker and manufacture method thereof. Anti-fake coding characters are printed on the safe line in the paper, and anti-fake coding bar information are printed on the paper surface, because the character and the bar are not in the same plane and belong to three-dimensional information, so the printing can be not completed at one time, and the manufacture and the falsification are difficult; the invention also provides processes of firstly overlaying line, then printing bar code, overlaying again and overprinting, which can avoid that end characters on the safe line can not be cut off, integrality and consistency of the information on the safe line can be kept, thereby avoiding misreading and false drop by consumers.

Description

technical field [0001] The invention relates to the fields of papermaking and printing, in particular to an information anti-counterfeiting marker embedded with a security thread in paper and a manufacturing method thereof. Background technique [0002] There is such a technical problem in the "supervision code identification" promoted by the National Product Quality Electronic Supervision Network: counterfeiters can take back the supervision code from the market, illegally copy the supervision code in batches from the custodian / handler, and then take one code for one Copying, or copying more than one yard (generally not higher than 1:50) is used to copy and fake. The inventor once bought a commodity with a fake "supervision code logo", and found through testing that the counterfeit "supervision code logo" was printed and copied on self-adhesive coated paper with a household inkjet printer. The applicant believes that since the supervision code logo is a flat "two-dimension...

Problems solved by technology

[0004] ①Consecutive arrangement and recording order: A group of anti-counterfeiting codes on the security line can only be arranged continuously (without intervals), and it is required to completely record a group of anti-counterfeiting codes that are finally printed on the security line in the computer query system database. Left and right (or called front and back) position sequence information - association relationship information, no slight record error is allowed, otherwise it will not be able to query; the process is very complicated

[0005] ② Long manufacturing cycle: Due to the adoption of the manufacturing process of "printing out the coding security line first, and then embedding the coding security line into the paper", digital printing factories, production line managers, paper mills, and glue coating factories are required , label printing factory and other five factories, at least two months of cooperation can complete the production of an order

[0006] ③The first and last characters are cut off, which is easy to misread and mischeck: the markers made are subject to different frictional resistance, different ambient temperature, uneven safety line material, uneven width, uneven thickness, etc. Factors will inevitably lead to a large error in the expansion and contraction of the security line, which in turn will cause the anti-counterfeiting code on the security line to be unable to be preset to the designated position

[0008] ④ Does not meet the current technical standards: the storage and query method of the anti-counterfeiting code does not meet the current technical standards of the anti-counterfeiting code query storage system

Because the current anti-counterfeiting code query storage system can only record a group of complete anti-counterfeiting codes, it cannot record the order of the left and right positions of a group of anti-counterfeiting codes that are finally printed on the security line. query system

[0009] ⑤ Disorganized markers, inconvenient to use and manage: the markers made, the anti-counterfeiting code on the inner security line is any one of the multiple sets of security codes adjacent to the left and right, and most of them are from Multiple groups of anti-counterfeiting codes are spliced ​​across groups, and the same batch of anti-counterfeiting codes on the security line of the same page of identification paper are not a complete set of anti-counterfeiting codes, and the logo cannot be seen. The arrangement order of objects is not convenient for workers to receive and use, and it is also not convenient for statistical management

[0010] To sum up, the current "supervision code identification", barcodes for logistics management, and anti-counterfeiting markers such as coded security lines have the following shortcomings: ①The anti-counterfeiting code is a flat "two-dimensional information", and the threshold for copying is too low, so it is urgently needed improve

②The unreasonable manufacturing process of "printing the coded security thread first, and then embedding the coded security thread into the paper" leads to large equipment investment, long production cycle, high manufacturing cost, and cannot be compatible with the current query system. Therefore, it has not been able to industrialize its patents so far

③The coded security thread anti-counterfeiting markers in the background technology are inconvenient for workers to use, inconvenient for statistical management, and easy to misread and mischeck
