Review of Anti-counterfeiting of Prints Based on Infrared Spectroscopy

Abstract

Infrared spectroscopy is a molecular selective absorption of certain wavelengths of infrared rays. So the infrared spectrum will show information about certain groups. The detection of the surface molecular information of printed matter based on infrared spectroscopy can effectively detect the authenticity of printed matter. This paper briefly describes the application of near-infrared spectroscopy, Fourier transform infrared (FTIR) spectroscopy; Fourier transform attenuated total reflection infrared (FTIR-ATR) spectroscopy for anti-counterfeiting detection of printed matter. Through the inductive analysis of some application examples to compare the advantages and disadvantages of the three techniques, the application of spectral analysis technology to the anti-counterfeiting detection of printed matter put forward some ideas and suggestions.
