Diode Array Micro Spectrometry of Colour Ink-Jet Printers
Abstract
Ink-jet printed documents, produced on 70 different brands and models of ink-jet printers available on the European market were analyzed by a micro spectrophotometer (reflection mode) using a diode array detector. The research focused on the measure of the reflection spectrum between 380 and 760 nm. Only the magenta and the cyan colours were measured since the yellow, according to a preliminary study, does not have a significant variation and subsequently was not analyzed. For each colour analyzed, three measurements were made and the mean was calculated. The results obtained enabled us to create a database. Such a database can be used to identify a particular model of printer (or groupof models) used to print a forged or counterfeit document. The problems encountered due to the paper stock and compatible ink cartridges (non-OEM cartridges) are also discussed.
