A preliminary investigation is conducted on electrostatic inkjet phenomena. High voltage is applied between an insulative capillary tube filled with water and a metal plate electrode. Inkjet phenomenon is observed at the dark discharge under conditions of appropriate tube diameter and water level. At the beginning of corona discharging, however, water mist is dispersed at wide angle from the tip of the tube. At higher voltage, water mist becomes to be dispersed like spray. Application of pulsed voltage can form a droplet that is synchronized with the pulse. This phenomenon is expected to be applied to a new inkjet print head.
