Abstract

In this work we investigated two potentially very useful methods in studying liquid-paper interactions and their application in ink-jet printing research. Problems associated with poor performance of uncoated papers in ink jet printing are excessive spreading of the ink on the surface of the paper and excessive penetration of the ink into the paper. These problems contribute to poor dot fidelity, feathering and low print density. Furthermore, some commercial papers that have good printability with black inks do not have the same printability with coloured inks. The reduced printability with coloured inks, in particular, is believed to relate to the different penetration patterns of black and coloured inks. In addressing this problem, the concept of "critical" surface free energy proposed by Aspler et al. was used to investigate the penetration behaviours of inks into paper samples. A confocal technique was used in this work to study the ink penetration profile inside the paper. Our results show that the concept of "critical" surface free energy of paper is a good tool for studying the interactions between papers and ink jet inks. Our results also suggested that the confocal technique is potentially very useful in studying the ink penetration profiles inside the paper. Advantages and limitations of this application of the confocal technique are discussed.
