Multiple anti-forge ink with memory code and testing method thereof

Abstract

The invention is a multiple anti-falsification ink with a memory code and a method of detecting the ink marks of writing with it, synthesized of general ink, magnetic memory material, infrared fluorescent material and UV fluorescent material, etc. and the detecting method: making magnetic-electric conversion on the code information in the magnetic material in the ink marks and detecting, identifying the code information, and the infrared light generator excites infrared fluorescent information in the ink marks and the UV light of the UV lamp excites long-short wavelength UV fluorescent information in the ink marks. It has good anti-falsification effect, and the handwriting contains an electromagnetic code, infrared fluorescent information and UV fluorescent information, detected by special apparatuses and the code has uniqueness, so that the falsifier is difficult to simulate, thus able to effectively the occurrence of forging signatures, altering, forging written pledges, and other illegal activities. It is applied to important bills of documents and notes, signature, contracts and documents, etc.

Description

technical field [0001] The invention relates to a writing ink, in particular to a multiple anti-counterfeit ink with memory codes, a detector and a method for detecting ink traces written with the ink. Background technique [0002] The anti-counterfeiting technology of existing ink has several forms, one is by mixing luminescent material in the ink, i.e. fluorescent powder, then irradiating the ink with a purple light lamp, and using the fluorescent reverse signal to judge and identify its authenticity, as in the Chinese patent ( Application number) 96200746 Combination writing highlighter for anti-counterfeiting and anti-theft, which is composed of a fluorescent writing pen with colorless writing ink containing organic ultraviolet fluorescent complexes and an ultraviolet counterfeit detector. Use it to write invisible signatures or passwords on documents and valuables, which can effectively prevent counterfeiting and anti-theft. Immediately after writing, use the ultraviole...

AI Technical Summary

Problems solved by technology

The disadvantage of fluorescent ink is that this technology only detects whether there is fluorescent material in the ink. This technology is still easy to be imitated, just add fluorescent powder to the ink.

[0003] The above-mentioned anti-counterfeiting inks or printing and writing materials have their own advantages and disadvantages. Some are more responsible in the production process, and some have poor anti-counterfeiting effects and are easy to be cracked.
