Abstract: A printer includes a printbar having plural dice partially overlap in the direction of rows and a halftoner. The dice receive nozzle firing data which determines when and where the individual print nozzles are to be operated in order to emit the colorant onto the media so as to form the desired printed image on a media. The halftoner is a bidirectional error diffusion halftoner that is structured to generate halftoned data. The halftoned data is mappable into the firing data. The halftoner includes a serpentine direction reverser which is structured to halftone print data image pixels in a first serpentine direction to form halftoned data and then to halftone print data image pixels in an opposite serpentine direction to form the halftoned data.

Abstract: There are provided a medium conveying device and an image recording apparatus that can convey a medium without the generation of wrinkles and floating. Projections having the same size are regularly disposed on the peripheral surface of an image recording drum to form recessed portions and protruding portions on the peripheral surface of the image recording drum. An interval between the projections disposed in a middle region is set to be smaller than an interval between the projections disposed in both end regions. Accordingly, when a sheet is pressed against the peripheral surface of the image recording drum by a pressing roller, forces for pulling the sheet to the outside from the middle in a width direction can be generated. As a result, the sheet can be made to come into close contact with the peripheral surface of the image recording drum without the generation of wrinkles and floating.

Abstract: Example implementations relate to swath height error compensation. Some examples may determine a density of an image to be printed in an overlap area of a printing material. The overlap area may include target pixels capable of being printed by a first set of drop ejection elements and a second set of drop ejection elements that are redundant to the first set of drop ejection elements. Some implementations may also determine a mask to apply to the first and second set of drop ejection elements based on the determined density, and the mask may designate at least one additional drop to apply to at least one target pixel in the overlap area by at least one of the first and second set of drop ejection elements. Some implementations may also apply the mask to the first set of drop ejection elements and the second set of drop ejection elements.

Abstract: An inkjet recording apparatus includes a calculation section, a selection section, and a recording head. The calculation section calculates respective densities of first regions in pairs included in the image. The selection section selects dot patterns corresponding to the respective first regions according to the respective densities of the first regions. The recording head ejects ink onto a sheet based on a dot pattern corresponding to a region of the image other than the first regions and the dot patterns corresponding to the respective first regions. The first regions in pairs corresponds to end portions in pairs among a plurality of end portions of the image that each extend in a conveyance direction of the sheet. The dot patterns corresponding to the respective first regions each have a density lower than a corresponding one of the densities of the respective first regions calculated by the calculation section.

Abstract: In an embodiment, a method of maintaining nozzles in a print-ready condition includes determining image content to be printed in an upcoming print swath, and for each ink color present within the image content, constructing an inked portion of an associated spit bar adjacent to the upcoming print swath to include the present ink color. For each ink color not present within the image content, an empty portion of an associated spit bar is constructed adjacent to the upcoming print swath.
