Recent Advances in the Forensic Dating of Blood Traces: A Minireview

On Hyperspectral Analysis of Water Soluble Writing Inks

“…There are numerous established methods for analysing inks. Menżyk et al in [2] give an exhaustive overview of ink analysis methods in forensic examination of documents, and divide the methods into following categories in order of inquiry:…”

“…• Mass spectrometry ( [2] lists mass spectrometry as part of spectroscopic methods, but for the different characteristics this paper distinguishes it from other spectroscopic methods) -destructive analysis of a sample to determine its precise chemical composition. • Spectroscopic methods -the latest group of methods analysing spectral properties of inks.…”

“…Hyperspectral Imaging (HSI) is another representative of spectroscopic methods, which on top of the spectral information provides the spatial distribution of the information. In the current ink analysis state-of-the-art as outlined by [2], and considering the recent developments in HSI techniques, the attention has been mostly concentrated on ballpoint inks, gel inks, printing inks and other kinds of artwork [3], [4]. Water soluble inks, such as drawing inks, calligraphy inks and fountain pen inks have gone mostly unexamined by the HSI methods.…”
