Thermal ink jet is a marking technology that uses explosive boiling within fluidic structures with dimensions of a few tens of microns to project droplets of water-based marking fluids having volumes of a few tens of picoliters at a substrate such as paper. In this presentation, we will provide a description of thermal ink jet and highlight some of the physical phenomena that are critical to a quantitative understanding of how thermal ink jet works. The descriptions will be highlighted by experimental data in both explosive boiling and jetting. Finally, some of the challenges in developing a quantitative understanding of thermal ink jet will be discussed.
