ABSTRACT
Microdrop ejection fluids intended for use in research and manufacturing have different operational optimizations from commercial printing inks, but many of the basic rheological requirements, such as appropriate viscosity, surface tension, and particle content, remain constant for all microdrop ejection systems. Not all of the fluid components used in commercial printing inks are needed for nonimage printing applications, but the functions of each additive should be considered to verify its relevance or lack thereof to one’s particular application.
