This study proposed the new technology for generating microjets for highly viscous ink. The present technology can eject only low viscous ink. In our technology, the jet is induced inside a thin tube partially submerged in a liquid. The meniscus inside the tube is kept deeper than that outside the tube. An impulsive force added at the bottom of a liquid container leads ejection of the microjets with high viscosity up to 1,000 cP. This study experimentally and numerically reveals the mechanism of our method.
