摘要： The invention relates to a method of printing a two-dimensional bit-mapped image having a number of pixels per row, the printhead having a row of ejection channels and each ejection channel having associated ejection electrodes to which voltages are applied in use. During printing, in order to cause volumes of fluid to be ejected from selected ejection channels of the printhead for printing, voltage pulses having values of predetermined amplitude and duration as determined by respective image pixel bit values generated by a raster image processor are applied, at a given pulse period, to the electrodes of the selected ejection channels. The part of the raster image corresponding to an ejection channel is scanned to determine the number of adjacent non-printing pixel periods prior to a pixel to be printed and, immediately prior to the printing of said pixel, a voltage pulse, having a value predetermined in accordance with the time, measured in units of the given pixel period, between the last pixel to be printed and said pixel to be printed, is applied to the ejection electrode.

摘要： An inkjet recording apparatus includes an ink particle generation unit that makes a pressurized ink injected from a nozzle into particles, a charging unit that electrically charges the ink particle of those subjected to particulation, which corresponds to a dot to be printed, a polarizing unit that polarizes the electrically charged ink particle in a polarizing electric field, a collection unit that allows a gutter to collect the ink particle corresponding to the dot that is not printed, and a character forming unit that forms a character as a dot matrix on a printing object. A phase detection charging signal is applied to the ink particle that is not used for printing when forming the dot matrix character so as to detect an optimum charging timing in a process of forming the dot matrix character.

摘要： A method of driving an electromechanical converter of a print head of a continuous inkjet printer, wherein the electromechanical converter is arranged to break up a continuous stream of ink into a plurality of drops. The method includes determining a modulation voltage to drive the electromechanical converter, at least a property of the modulation voltage being controlled to take into account movement of a break up point of the continuous stream of ink, and to ensure that in a characteristic of modulation voltage versus a property at least indicative of a break up point of the continuous stream of ink, the characteristic has a predetermined gradient, or a gradient related to this predetermined gradient; and driving the electromechanical converter at the determined modulation voltage.

摘要： A method of reducing print-density variations in printers, particularly multi-deflection continuous-jet printers, including printing elements arrayed along the X-axis for printing on a substrate moving relative to the printing elements along the Y-axis. The method includes controlling the printer to print a test pattern having a plurality of strips extending along the X-axis, wherein the gray-level of each printed strip is the same along the X-axis, but varies from one strip to the next along the Y-axis; analyzing the printed test pattern to detect gray-level variations in the printed strips; preparing a density correction table of gray-level corrections for each X-coordinate; and controlling the printing elements in accordance with the density correction table to reduce the detected gray-level variations.

摘要： An ink jet printhead (8) includes a drop generator (11) having an attached orifice structure (10) forming a jet array adapted to use ink jet fluids with a charge device (12)disposed opposite the jet array (15) forming a gap (13). The charge device includes a dimensionally stable, non-porous substrate layer (14) having a high load to deflection ratio, one or more electrically conducting leads (16) bonded to the substrate layer, an insulating protective layer (20) disposed over the electrically conducting lead, and a non-wetting polymer (22) coating compatible with the ink jet fluids disposed on the insulating protective layer. The coating reduces the capillary forces that hold liquid in the gap between the orifice structure and the charge device.
