Print Quality and Particles (PQP): Optimizing the interaction of water-based inks with porous substrates

Inkjet printing shifts towards the use of water-based ink for environmental reasons. These inks are complex mixtures containing pigment- and latex-particles as the main contributors to print quality. As most printing substrate are porous, an ink migrates into a substrate due to capillary suction and drags the particles deep into the printing substrate. This leads to a loss of print quality as the particles should stay at the surface. The project PQP investigates the motion of particles into porous media in order to understand the relation between penetration depth and the particlesubstrate interaction. With MRI and CSLM particle motion will be visualized during transport both on the macro- and on the microscale. The obtained experimental data will be used to develop a multiscale model for predicting the motion of ink into a porous medium. This will enable targeted and accelerated development of inks.
