摘要： Inkjet printer apparatus includes a pressure regulated tank (20) having an inlet (21a) connected to an ink reservoir (2), and an outlet (21b) connected to a printhead (41) including nozzles (42) for discharging continuous streams of ink drops towards a substrate for printing thereon and gutters (not shown) for intercepting the ink drops not to be printed. The apparatus further includes a bypass lines (27) between the tank outlet (21b) and the ink reservoir (2), a bypass control valve (29) for controlling the flow rate via the bypass line (27) enabling the flow rate to be preset during draining the tank (20) and a pump (11) controllable to enable precalibrating the pump (11) during filling of the tank (20).

摘要： Ink jet printing apparatus includes a linear array of jet modules (103) each having an inlet (108) for receiving ink, an outlet (110) for re-circulating the ink, a nozzle (105) for discharging ink in the form of droplets, and a perturbation device (106) for causing a continuous stream of ink droplets to be discharged from the respective nozzle (105). The apparatus further includes an ink supply system having an inlet manifold (107a), an outlet manifold (107b), and a plurality of connecting passageways connecting the jet modules (103) in parallel between the inlet and outlet manifolds (107a, 107b). The connecting passageways connect the inlet (108) of each jet module (103) to the inlet manifold (107a) and the outlet (110) of each jet module (103) to the outlet manifold 8107b), such as to define a T-connection of each jet module (103) with the inlet and outlet manifolds (107a, 107b). Such a construction reduces the mass of each jet module (103) thereby permitting printing at higher frequencies and with smaller ink droplets.
摘要翻译：喷墨打印设备包括一个喷射模块的线性阵列，每个射流模块都具有用于接收油墨的入口，用于使油墨重新循环的出口，用于以液滴形式排出油墨的喷嘴，以及用于引起连续的油墨流的扰动装置液滴从相应的喷嘴排出。该装置还包括具有入口歧管，出口歧管以及在入口歧管和出口歧管之间并联连接喷射模块的多个连接通道的供墨系统。连接通道将每个喷射模块的入口连接到入口歧管和每个喷射模块的出口到出口歧管，以便限定每个喷射模块与入口和出口歧管的T形连接。这样的结构减少了每个喷射模块的质量，从而允许以更高的频率和更小的墨滴印刷。

摘要： A method and apparatus for printing a desired pattern on a substrate (4) by discharging continuous stream of liquid ink drops (5) from nozzles (2) towards the substrate (4), and selectively charging the liquid ink drops (5) with multi-level charges deflecting them different amounts. Some of the liquid ink drops (5) are thus directed to different locations on the substrate (4) for printing the desired pattern thereon, while other liquid ink drops (5) not to be printed are intercepted by a gutter (8) before reaching the substrate (4). At least some of the liquid ink drops (5) to be printed being either uncharged or charged with a multi-level charge of one polarity, while all the liquid ink drops (5) not to be printed are charged with a charge of the opposite polarity. Each stream of ink drops (5) discharged from a nozzle (2) is illuminated with stroboscopic light (10) at the same frequency as the drop formation, and the illuminated stream is optically sensed on the fly from determining various conditions, including ink velocity, X-axis offset and Y-axis offset.

摘要： A method and apparatus for inkjet printing by means of a plurality of inkjet nozzles arranged in at least one row and having spaced, parallel nozzle axes for emitting liquid ink drops towards the substrate, and multi-level charging anddeflecting plates controlled to deflect individual drops to selected locations on the substrate with respect to the respective nozzle axis according to the pattern to be printed. The multi-level charging and deflecting plates are controlled to cover, for each nozzle, a line section which includes two non-contiguous deposit zones to receive ink drops from the respective nozzle, separated by a non-deposit zone not to receive ink drops from the respective nozzle. Various arrangements are described, wherein the nozzles are arranged in a single row or two staggered rows; the printing is effected in a single pass or two passes; the nozzle line sections are overlapping, contiguous orspaced from each other; and the deposit zone of one nozzle overlaps at least a part of the deposit zone of another nozzle.
