Pen inks on paper substrates were analysed by Raman spectroscopy and time-of-flight secondary ion mass spectrometry (ToF-SIMS) over four months. Peaks associated with triarylmethane dyes were monitored to establish degradation patterns, which could be used to establish the relative age of ink entries on handwritten documents for forensic purposes.
