    • The invention relates to a solution for limiting the consumption of volatile compounds, such as solvents, initially present in ink during the ejection of the latter in a binary continuous ink-jet printer. According to the invention: - it is selected an ink which volatile compounds have a Schmidt number Sc equal to one or superior; - the gutter (7) for recovery and collection of ink not intended to print and issued from a jets curtain is judiciously positioned to swallow the air flow laden by vapour of volatile compounds entrained by the ink jets curtain; - a depression level is set in the gutter to remove the volumetric flow of the swallowed flow of air; - air is injected in the vicinity of the nozzle plate of the print head to compensate recovered volumetric air-flow.
    • 本发明涉及一种用于限制在二进制连续喷墨打印机中喷射墨中最初出现在油墨中的挥发性化合物(例如溶剂)的消耗的解决方案。 根据本发明: - 选择挥发性化合物的施密特数Sc等于或等于1的油墨; - 用于回收和收集不用于从喷射窗帘打印和发出的油墨的槽(7)被明智地定位成吞噬由喷墨窗帘夹带的挥发性化合物的蒸气所载的空气流; - 在沟槽中设置抑制水平以消除吞咽空气流的体积流量; - 将空气喷射到打印头的喷嘴板附近以补偿回收的体积气流。

    • The invention relates to a continuous inkjet printer or a print head of such a printer. It includes electrical means for compensating (R1, R2) for mechanical crosstalk between adjacent stimulation chambers, where these means (R1, R2) simultaneously with the transmission, to a stimulated chamber, of a stimulation pulse on a stimulation line (9, 91, 92, 9n) send a pulse for compensating for mechanical crosstalk on each of the lines (9, 91, 92, 9n) supplying an actuator (6) for the chamber adjacent to the stimulated chamber. The invention is characterized with specific ratios between the peak amplitude of pulse for compensating for the crosstalk and the peak voltage value of the stimulation pulse in function of the gaps between consecutive nozzles.

    • 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.
    • 对于打印,使用连续偏转喷流的原理:装置排出液体的连续流,该液流被多个偏转电极产生的电场偏转并且朝向沟槽排出。 液滴的印刷通过将连续射流分段成与偏转电极上游的屏蔽电极相对形成的部分进行,使得该部分不被偏转并且可以朝向基底。 偏转电极(22,24)由绝缘体(26)分开,并且可变电位被施加到每个电极; 整个电极组的电位消失,使得射流(2)不被充电。

    • The invention relates to a new control method for controlling the printing of a binary continuous inkjet printer provided with a printhead (20) with a set of deflection electrodes (8a, 8b; 9a, 9b) shared by all of the nozzles of the head, at least one pair of electrodes (8, 9) supplied in phase opposition relative to each other, and actuators (6) to which pulses are sent to form a distance Lbr from the plane of the nozzles (11), from the break of a jet discharged by a nozzle (3) in communication with a stimulation chamber (2) to which said actuator is mechanically coupled, drops not able to be electrically charged or jet segment subjected to the electrostatic influence of the deflection electrodes. According to the invention, the pulses are controlled so as to minimize the total electrical charge taken on by the ink jet segments inside a volume of influence of the electrodes.
