Abstract
This study investigated the penetration of the ink vehicle into the printing paper. In order to obtain useful information on the interaction between the substrate structure and the ink, we developed a new technique by combining the FIB method with an electron probe micro analysis (EPMA) after osmium labeling of the unsaturated carbon double bonds in the vehicle. Using this novel method, we could first observe the distribution of the vehicle after it transferred to and penetrated into the paper.
