摘要： The invention relates to an inkjet printer (10) comprising a print head (1) which is equipped with an internal stimulation system (31). According to the invention, the stimulation system can be used to create: (i) an upstream break in a break position (11) upstream of a jet (30), said break forming drops (33) which are used for printing and jet segments (38) in a zero potential area; and (ii) a break in the jet (30) or jet segment (38) in a downstream break position (12), said break forming drops (43) which are recovered in a non-zero potential area. A sorting system (35) which is common to all of the jets (30) of the head can be used to simplify the head and to reduce the size thereof.

摘要： Ink jet printing method, in which the jet (14) is broken up in small and large drops at a fixed point (B), and the drops (16a, 16b) are charged according to the length (l, L) of the break segment (18), in other words according to their diameter. This configuration overcomes transition problems. The charging means (22) can also selectively deflect drops (16b).

摘要： For printing, the principle of the continuous deflected jet is used: a device (1) discharges a continuous stream (2) of a conductive liquid, which is deflected by an electric field created by a deflecting electrode (8) and directed toward a gutter (6). The printing of drops (12) is performed by fragmenting the continuous jet (2) into a segment (10) formed opposite a shield electrode (14) upstream of the deflecting electrode (8), so that the segment (10) is not deflected and can be directed toward a substrate (16).

摘要： 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.

摘要： The generator according to the invention operates by strong stimulation in the form of pulses (τ) so as to generate drops, particularly for ink jet printing purposes. This choice enables breaking the jet (30) close to the ejection (16) and reduces the interference ratio. A generator with piezoelectric stimulation is particularly suitable.
