    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： 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.
