MARKING METHOD AND APPARATUS

摘要

MARKING METHOD AND APPARATUS A method and apparatus are provided for providing droplets that are suitable to mark a recording surface with a high degree of resolution and which are quickly responsive to electrical input. A shaft electrode is positioned with respect to a supply of marking liquid such that its propellant end is just above the surface of the marking liquid. A field is established between the shaft electrode and one external electrode causing droplets to be propelled from the marking liquid supply covering the shaft electrode onto record receiving means.
