| This paper reports on the microscopic assessment of representative specimen cross-sections prepared by microtomy and ultramicrotomy with emphasis in structure-property information using optical, scanning and transmission electron microscopy, namely, the absolute optical density delta, the measured effective printing coverage (C) over tilde, the averaged pigment-based ink layer thickness (t) over bar, and the morphology at 100% nominal printing coverage. This work shows that for different test patches printed at the same nominal printing coverage a number of different printing schemes yield a pre-defined absolute optical density delta which basically depends on the measured effective printing coverage (C) over tilde and the type of pigment-based inks used (spectral absorptivity m not equal infinity) and therefore on the averaged pigment-based ink layer thickness (t) over bar. A method for estimating the spectral absorptivity in is presented which combines the absolute optical density delta of the test patch and the averaged pigment-based ink layer thickness (t) over bar as measured from cross-sectional electron microscopy. @ 2004 Elsevier Ltd.
