摘要： A liquid ejecting device can print a high quality image having an increased number of gradations without having a complex head structure, and is suitable for use in a line head. The liquid ejecting device includes a head in which liquid ejecting portions including nozzles are arranged in parallel. A droplet can be deflected at the moment of ejection from the nozzle of each of liquid ejecting portion. By controlling at least two different liquid ejecting portions in adjacent positions to eject droplets, a pixel column or a pixel is formed.

摘要： An ink jet printer includes: a main scan driving unit 3 that drives a print head 2 with nozzle arrays 2a and 2b in a main scanning direction relative to a printing medium S, where each nozzle array has a preset number of nozzles arranged at a fixed nozzle interval; a sub-scan driving unit 4 that drives the printing medium S in a sub-scanning direction; a driving unit controller 5 that controls the main scan driving unit 3 and the sub-scan driving unit 4 to locate the print head 2 at predetermined positions; and a print head driving unit 7 that supplies electric power to the print head 2 based on print image data which includes multi-value tone information and is stored in a data storage unit 6. The binary outputs based on the jetting or non-jetting of ink and the positional control by the driving unit controller 5 cause the print head driving unit 7 to superpose dots upon the dots that have already been formed, so as to carry out multi-value outputs.

摘要： Method for multiplying the speed-resolution product of a raster scanning or imaging device such as an inkjet printer, and a resulting pixel image data structure, are disclosed. Illustratively, a 300-dot per inch (dpi) by 600-dpi logical pixel image is mapped (14) to a corresponding, non-overlapping physical dot image, and the printer's inkjets are fired (22) responsive to the dot image to direct generally spherical ink droplets onto paper at 600-dpi resolution grid timing in order effectively to double the horizontal resolution of the printed pixel image, without increasing the firing rate of the print head. In order to accomplish this, and to avoid ink dot overlap, the printable pixel image is thinned (18, 20) before it is printed (22) by a method that leaves no visible horizontal or vertical gaps by selectively turning off pixels within a 'black' image that were on and that otherwise would result in ink dot overlap and slower print head speeds were the inkjets cycled at 600-dpi resolution timing. Pixel thinning (18, 20) is performed substantially without adversely affecting pixel image edge definition.

摘要： A method of printing a two-dimensional bit-mapped image having a number of pixels per row for printing using a plurality of overlapping printheads or a printhead or printheads indexed through overlapping positions, the or each printhead having a row of ejection channels, each ejection channel having associated ejection electrodes, the method comprising: applying a voltage to the ejection channels sufficient to cause concentration of particles in the printing fluid at the ejection channels, applying voltage pulses of respective predetermined amplitude and/or duration, as determined by respective image pixel bit values, to the electrodes of the selected ejection channels in order to cause volumes of printing fluid to be ejected from selected ejection channels of the overlapping printheads, thereby forming a pixel of a predetermined optical density, adjusting, for each row of the image, the values of the voltage pulses to be applied to the overlapping printheads to form pixels printed by overlapped ejection channels in dependence on the position of the pixel within an overlapped region of the printheads and in dependence on the predetermined optical density of the pixel, wherein, for at least one pixel in the overlapped region, the total volume of ink ejected by the overlapped channels is greater than that required if that pixel were formed by a single ejection channel.
