We worked on the characterisation of the ball-pen inks, and in particular we studied the line-crossings to determine the chronological sequence of the lines, by means or micro-Raman spectroscopy.

We realized an extensive collection of Raman spectra of inks for ink-jet printers, also using the SERS (Surface-Enhanced Raman Spectroscopy) technique, in order to identify the possible sources of printed documents. The results of this study, combined with UV/visible micro-reflectometry measurements, were helpful in the solution of real investigative cases.

We performed also a combined Raman - Electron Microscopy study for the identification of gun powder residues
