In this study, 20 colored inkjet ink samples (both original and refilled) were analyzed on the basis of their dye components by using thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC). Dyestuffs in the inks were extracted using ethanol and picric acid. Two solvent systems were found efficient to differentiate the all colored inkjet ink samples. TLC and HPTLC differentiated all the ink samples.
