Micro-Raman Spectroscopy of Color Inkjet Printed Documents
Abstract
Inkjet printed documents produced by 22 different brands and models of color inkjet printers available on the Swiss market were analyzed by micro-Raman spectroscopy using a near infrared (NIR) excitation wavelength of 785 nm. The magenta components were discriminated into 11 groups, but the cyan inks could not be further distinguished. The yellow inks did not exhibit significant Raman scattering; however, the cyan inks could not be further distinguished. The yellow inks did not exhibit significant Raman scattering, but the signals may have been concealed due to strong interference from the paper background.
