Abstract

The invention discloses an anti-counterfeiting method using a carbon two-dimension code. The anti-counterfeiting method comprises the following steps: adding a nano fluorescent material into carbon printing ink printed with a two-dimension code, wherein the nano fluorescent material is hidden in the printed matter and cannot be observed by naked eyes, and the nano fluorescent material cannot emit a yellow visible light until a blue visible light with a specific frequency irradiates the printing ink, so that the anti-counterfeiting purpose can be achieved; besides, the fluorescent light emitted by the nano fluorescent material is yellow, therefore the nano fluorescent material is more suitable for being mixed in black ink for use, especially in a black carbon bar code for use. The anti-counterfeiting method using the carbon two-dimension code has the advantages of being low in cost, and does not influence the aesthetics of product packaging.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for commodity identification by using a carbon two-dimensional code. Specifically, it relates to a method for realizing anti-counterfeiting by adding specific invisible nano-fluorescent ceramic components into the ink. Background technique [0002] In view of social public security, commercial anti-counterfeiting needs and the increasingly rampant counterfeit goods in the circulation field in recent years, commodity anti-counterfeiting technology at home and abroad has developed rapidly. At present, popular anti-counterfeiting technologies are: printing anti-counterfeiting special paper; printing anti-counterfeiting special ink; infrared and ultraviolet irradiation commodity anti-counterfeiting marks; commodity password telephone, network query; various spectrum lasers, fluorescent anti-counterfeiting marks; pattern; magnetic wire; precision electronic weighing; thermal discoloration; RFID radio f...
