Abstract

A high resolution printing method is disclosed, implemented in a printer in which a continuous ink jet is broken up into drops (G) in a charging electrode (6) where they are selectively charged electrostatically, said drops then pass between deflection electrodes (9), the appearance of a satellite drop (Sn) from a main drop is caused by application of an appropriate voltage in the charging electrode during formation of said main drop and the coalescence of a satellite drop thus formed intended for printing with the following main drop is prevented, also by application of a voltage to the charging electrode during the formation of said main drop.
