<p>For printing, the principle of the continuous deflected jet is used: a device discharges a continuous stream of a liquid, which is deflected by an electric field created by a plurality of deflecting electrodes and directed toward a gutter. The printing of drops is performed by fragmenting the continuous jet into a segment formed opposite a shield electrode upstream of the deflecting electrode, so that the segment is not deflected and can be directed toward a substrate. The deflection electrodes (22, 24) are separated by an insulator (26) and a variable potential is applied to each electrode; the potential for the entire set of electrodes cancels out such that the jet (2) is not charged.</p> |
