Inkjet printing delivers droplets with picolitre volumes onto a substrate. This thesis focuses on improving the quality of inkjet prints by controlling the particle distribution in the deposit. To this end, the internal flows in evaporating droplets were compared on purpose-built imaging rigs. Formulations were developed for deposit control based on the results of this analysis. Initial studies of pure solvents determined the influence of the substrate wettability and thermal conductivity on evaporation. It was demonstrated that an isothermal model accurately predicted the drying times of picolitre droplets, provided that evaporative cooling was insignificant. Evaporation of simplified model inks (two solvents + latex particles) was t...
