Differentiation of Inks Used for Seals by Confocal Raman Microscopy and Fourier Transform Infrared Microscopy

April 01, 2015

The analysis of seals, mostly via the ink types, can provide evidence to authenticate the related documents and can play a key role in legal cases. In the present study, a method to discriminate red seal inks using Raman microscopy and Fourier transform infrared (FT-IR) spectroscopy was developed.
