Abstract

We have investigated the inter-relationship between the ink-jet printability and the physical fluid properties by monitoring the droplet formation dynamics. Printability of the fluids was judged based on the inverse of Ohnesorge number ($Z^{-1}$) that relates to the viscosity, surface tension, and density of the fluid.
