    Abstract

    Colored toner samples and counterfeit money processed from color photocopiers were collected from the same six manufacturers. Through infrared spectroscopy, a spectral match between the standard toner prowder and the toner extracted from the respective copies counterfeit banknote and documents was achieved. The results allowed the identification of the manufacturers and models, except for one manufacturer for which only partial identification was obtained. The toners were characterized and classified into different groups. Characterization or elimination of the toner extracted from counterfeit money processed by suspected photocopiers, is foreseen through building a transpose library of infrared data. Gas chromatography/mass spectrometry results showed that it can be used as a complementary method.
