Near-infrared absorption anti-counterfeiting method

Abstract

The invention relates to a near-infrared absorption anti-counterfeiting method, comprising a near-infrared absorption anti-counterfeiting ink and a special invisible bar code identification pen, the near-infrared absorption anti-counterfeiting ink is used for printing one dimensional code, two-dimension code and numerical code information, the special invisible bar code identification pen can read the one dimensional code, two-dimension code and numerical code information under the action of high-energy rays, so as to judge true and false and achieve anti-counterfeiting purpose. Users can select the one dimensional code, two-dimension code and numerical code information arbitrarily according to needs, thereby achieving anti-counterfeiting uniqueness, in addition, the decoding and analysis of the one dimensional code, two-dimension code and numerical code information printed by the near-infrared absorption anti-counterfeiting ink are difficult, and imitation difficulty is high. The near-infrared absorption anti-counterfeiting method integrates multiple disciplines and multi-field, the production equipment investment is high and the production process is complex.

Description

technical field [0001] The invention relates to a near-infrared absorption anti-counterfeiting method, which belongs to the technical field of anti-counterfeiting. Background technique [0002] In recent years, anti-counterfeiting technology has developed rapidly in our country. The common method is to add some specific substances to the ink to make fluorescent ink, photochromic ink, temperature-changing ink and magnetic ink to print various bills, trademarks, and even Banknotes, etc., to prevent their counterfeiting. But this type of technology has been used very widely at present, and is easy to imitate, has poor confidentiality, and low anti-counterfeiting strength, so it is very necessary to develop new anti-counterfeiting technology. Contents of the invention [0003] In order to overcome the shortcomings of the existing anti-counterfeiting technology, such as inks that are easy to imitate, poor confidentiality, and low anti-counterfeiting strength, the present inven...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing anti-counterfeiting technology, such as inks that are easy to imitate, poor confidentiality, and low anti-counterfeiting strength, the present invention creates a new anti-counterfeiting method, which includes a near-infrared absorbing anti-counterfeiting ink and a special invisible barcode recognition pen. The anti-counterfeiting ink is made by adding one or more near-infrared absorbing materials into the ink and fully grinding it. The near-infrared absorbing anti-counterfeiting ink is used to print one-dimensional codes, two-dimensional codes and digital information, making it an invisible barcode that is invisible to the naked eye. , through the special invisible barcode recognition pen to read the above-mentioned one-dimensional code, two-dimensional code and digital information under the action of high-energy rays, so as to judge the authenticity and achieve the purpose of anti-counterfeiting
