摘要： In a first aspect, in a continuous stream ink jet printing system generating a plurality of streams of ink droplets, a chosen number of droplets of each stream is less than all of the droplets of the stream. A controller of the printing system is arranged to consider for printing from among a number of the droplets of each stream greater than the chosen number with the proviso that the resultant selection made observes this constraint. In second and third aspects, the controller of the printing system is arranged to create a set of droplet print positions ideal for representing an image to be printed, which set is permitted to include print positions offset from print positions of a nominal matrix, at speeds of operation less than the predetermined speed. The controller compares the positions at which droplets are deposited at the lower speed with the set of ideal positions. The controller decides which droplets to print in dependence on the comparison.

摘要： A droplet generator for a continuous stream ink jet print head includes an elongate cavity for containing the ink, nozzle orifices in a wall of the cavity for passing ink from the cavity to form jets. The nozzle orifices extend along the length of the cavity. An actuator is disposed on the opposite side of the cavity to the wall for vibrating the ink in the cavity by itself vibrating relative to the wall. The vibration is such that each jet breaks up into ink droplets at the same predetermined distance from the wall of the cavity. The thickness of the wall through which the nozzle orifices extend is less than 90 &mgr;m. The wall includes a planar member secured to the remainder of the droplet generator so as to form a boundary which extends around the nozzle orifices and within which the planar member is unsupported. The boundary includes first and second boundary lengths which extend along the length of the cavity on either side of the nozzle orifices. The distance between the first and second boundary lengths being less than 1700 &mgr;m.

摘要： An ink jet array printer in which the printing voltage waveform applied to each raster of drops formed in each printing gun comprises at least two successive sets of voltage levels which each arrange the raster drops in a group in time order of drop formation for each set of voltage levels so that corresponding drops in each of the groups formed in the raster, if charged for printing, have similar differences of voltage level and have similarly spaced print locations in the line section of drops printed by the printing gun. First and second correction voltages are applied to the charging voltage levels, the first to correct for the influence of the preceding drop and the second for the electrostatic and aerodynamic drag forces of a small number of drops influencing the drop being corrected. The set of second correction voltages derived for any particular drop being used also for corresponding drops in the other group(s).
