    Abstract: The electrohydrodynamic print head (1) comprises a nozzle layer (4) with a plurality of nozzles (8). A feed layer (6) is arranged above nozzle layer (4). It contains feed ducts (20a, 20b, 52) for feeding ink to the nozzles (8) as well as electrically conducting feed lines (26, 46, 50a, 50b) for feeding voltages to electrodes (40, 14, 32) at nozzles (8). The feed layer (6) comprises one or more dielectric sublayers (6a- 6f), which is/are structured to form the feed ducts (20a, 20b, 52) and feed lines (26, 46, 50a, 50b). Some of the sublayers (6a - 6f) contain vertical via sections (20a) and others contain horizontal interconnect sections (20b). The feed layer (6) is structured for customizing the print head (1) easily.

    Abstract: A method, apparatus, and system are described herein for driving a droplet ejection device with multi-pulse waveforms. In one embodiment, a method for driving a droplet ejection device having an actuator includes applying a multi-pulse waveform with a drop-firing portion having at least one drive pulse and a non-drop-firing portion to an actuator of the droplet ejection device. The non-drop-firing portion includes a jet straightening edge having a droplet straightening function and at least one cancellation edge having an energy canceling function. The at least drive pulse causes the droplet ejection device to eject a droplet of a fluid.

    Abstract: An electrohydrodynamic printing system includes a nozzle that dispenses a printing fluid and a substrate support. The nozzle includes a conductive portion. A voltage source applies a voltage differential between the conductive portion of the nozzle and the substrate support. A controller is configured to provide a burst mode waveform to the voltage source such that a drop of the printing fluid is caused to form from the conductive nozzle and travel toward the substrate support.

    Abstract: 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.
