Abstract
A combined numerical and experimental study reveals the optimal range of fluid properties for inkjet printing. The parameter space of fluid viscosity and surface tension required to produce single drops at a prescribed speed is identified and shows an additional restriction on the Reynolds number in order to jet single droplets.
