Optical properties are an essential quality measure when papers are printed with an ink to produce an image on paper. Measurement of optical properties, such as print gloss, as a function of time provide means to study ink setting behaviour and paper-ink interactions. This study compares three different methods for measuring dynamic print gloss: a dynamic gloss meter, a diffractive optical element based glossmeter (DOG) and a polarized light reflectometer. Four double coated papers were printed at varying ink levels. The technical details of the measurement techniques are compared and discussed. Dynamic print gloss results are evaluated in the light of current ink setting theories. Each of the methods is very applicable to ink setting studies. The results indicate that the measured print gloss is a combination of the influences from printing conditions, ink filament formation in the printing nip, and ink-leveling.
