Liquid jet e.g. ink jet, deflecting method for use during ink-jet printing, involves generating variable electric field along hydraulic path, and deflecting liquid jet by field by mobilization of charges within jet

摘要

The method involves forming a conducting liquid jet e.g. ink jet, exiting at a preset speed by a nozzle (4) of a pressurized chamber based on a hydraulic path (A). A variable electric field is generated along the path by setting potential of electrodes (22, 24) which are isolated from each other and form an electrodes network (20) extending along electrodes plane (28). The potential applied to each electrode is variable and the potential applied to the series of electrodes is null spatial and temporal averages. The jet is deflected by the field by mobilization of charges within the jet. Independent claims are also included for the following: (1) a method for selective deflection of sections of continuous jet (2) a method for generating a film of jet spraying drops (3) a method for ink-jet printing (4) a device for selectively deviating conducting liquid drop, comprising a network (5) a print head comprising an ink collecting unit.
