The effect of base paper hydrophobicity and polyelectrolyte multilayer surface treatment on the subsequent liquid absorption and ink–substrate interaction was studied. It was found that the internal sizing degree affects the inkjet print quality, but that it is dependent on deposited polyelectrolyte layer chemistry and composition. A rather different ink absorption and spreading behavior was seen with dyes than with pigment-based inks.
