In this work the methodology is developed to study spreading and penetration of a custom ink-jet ink formulation, containing hydrophobic cationic crystal violet dye, ethoxylated surfactant, and ink solvent marked by lithium salt. With a new technique
utilizing Time-of-Flight Secondary Ion Mass Spectrometry imaging, the ink component distribution and its effect on print quality of uncoated and coated papers are evaluated.
High spatially resolved images obtained by ToF-SIMS illustrate differentiation of
individual ink components, with ink solvent spreading more than the dye in all paper
samples. Uncoated papers show greater and more irregular spreading leading to poor
edge definition and poor print quality. Large separation of the dye from the solvent in the vertical direction of multipurpose and photo glossy ink-jet paper suggests a step-wise progression of ink penetration: ink flows through a more porous structure in the x-direction before advancing to the next sublayer in the z-direction of paper.
