The Pattern Recognition of Blue Ballpoint Pen Writing Inks by ATR Technique

Abstract

Abstract: Asystematically analytical method for the recongnition of blue ballpoint pen ink has been studied by ATRtechnique of Fourier transform infrared(FTIR) spectrometry. By using this method, a total of 108 blue ink samples have been divided to 18 groups depending on the main component. The spectral characteristics of these inks such as peak location, peak intensity etc. were described by the way of pattern recognition; and the species of inks have been able to be recognized by their correlation coefficient(λ). This system has provided a best reliable and nondestructive method for the determination of ballpoint pen ink.

Key words: Ballpoint writing inks, Attenuated total reflection, Pattern recognition, Nondestructive analysis
