Simple pore-volume measurements are not sufficient to fully understand the absorption of inkjet inks into microporous inkjet media, especially as manifested in print artifacts such as ink coalescence, ink bleed and ink drying time. In this paper, we will investigate the influence of other pore characteristics such as pore size and distribution on the aforementioned print attributes, using porous silica pigments, both commercial and under development. This paper will also look at the influence of coat-weight in overcoming bleed and coalescence and its implications for microporous coating design.
