Summary:This chapter is concerned with developing an understanding of the way inkjet fluid properties can be characterized. Inkjet processing involves forcing an inkjet fluid through very small nozzles. The whole jetting process is extremely delicate and sensitive to many variables. The viscosity and viscoelasticity of inkjet fluids are not easy to measure because the base viscosity is low and generally close to that of water, and in addition, the viscoelasticity of the fluid is difficult to measure because the viscoelastic relaxation times of inkjet fluids are generally submillisecond. Another difficulty is the measurement of the extensional behavior of inkjet fluids where again the low viscosity and short timescales involved mean that a special apparatus is required. In order to characterize the rheology of inkjet fluids, it has been necessary to develop a special experimental apparatus to access the required viscosity and time domain of these fluids.
