Discrimination and source correspondence of black gel inks using Raman spectroscopy and chemometric analysis with UMAP and PLS-DA
In the examination of forged documents, ink analysis plays an important role and the forensic scientist is required to opine on the origin of ink and colorants when the physical appearance is similar. Also required is to link the ink with its source as this has an important bearing in solving cases...
