Two methods are presented for the identification of ink, both of which are currently being used by laboratories involved in inkysis. Both methods incorporate physical and chemical procedures. The differences are primarily in chemical methods involvintests and thin layer chromatographic TLC techniques..The most widely used technique for comparing and identifying inks is TLC. This technique separates the dyes in the ink and the invisible organic components in the ink. This allows a direct comparison of the composition of inks being examined on the same TLC plate. To determine the relative concentrations of dyes present .
