ABSTRACT:
The UV- Visible absorbance profile of cyan, magenta, yellow and black coloured inkjet printer inks for the differentiation and comparison was obtained by scanning the ink extracts under the wavelength range of 200-800 nm. The various parameters of absorption studies of extracts of different components of printer ink formulations in the visible and UV region enables to differentiate and distinguish different colour print document samples of distinct composition by their characteristic absorbance spectra and profile pattern.
