Method and apparatus for printing image

摘要

In printing images, desired portions of surface of ink are risen by utilizing electrostatic force (Coulomb force), whereby the ink is transferred onto a printing medium placed adjacent to the ink surface. In order to rise the desired portions of the ink level, a printing apparatus has such construction that a plurality of printing electrodes are provided in such a way that the end portions thereof are positioned slightly below the ink surface level, while an auxiliary electrode is disposed opposite to the printing electrodes over the ink surface.
