  • Patent number: 10719746
    Abstract: Ink containing metal particles is ejected from a print head, in accordance with a plurality of print ratios corresponding to a plurality of scans of the print head relative to a unit region of a print medium. At least one of the plurality of print ratios is set as a high print ratio which is higher than others. A height of the high print ratio, in a case where a scan corresponding to the high print ratio is a Lth (L: integral number) scan in the plurality of print scans, is higher than a height of the high print ratio, in a case where a scan corresponding to the high print ratio is a Nth (N>L; N: integral number) scan in the plurality of print scans.

  • Patent number: 10654286
    Abstract: Broadly speaking, embodiments of the present technique provide apparatus and methods to print an image using masking techniques that control the operation of a droplet deposition head having at least one faulty nozzle. More specifically, an image is analysed to determine a pixel colour density for each pixel of the image. A masking technique is provided which may distribute the droplets (or sub-droplets) that a faulty nozzle is assigned to print among one or more neighbouring, functioning nozzles.

  • Patent number: 10639902
    Abstract: An inkjet print head includes an ink supply substrate having an ink supply channel in fluid communication with an ink supply connector channel for receiving ink from an ink reservoir and in fluid communication with an ink return connector channel for supplying ink to the ink reservoir; a droplet forming unit arranged on the ink supply substrate and having an ink inlet surface, in which ink inlet surface an ink inlet port for receiving ink from the ink supply substrate is arranged; a manifold chamber formed over the ink inlet surface of the droplet forming unit; and a filter arranged between the ink supply substrate and droplet forming unit. The filter has a first filter surface at an upstream side and a second filter surface at a downstream side. Filter holes extend from the first filter surface to the second filter surface. The first filter surface forms a wall of the ink supply channel.

    Abstract: A control device is for controlling a printer. The printer is configured to print by alternatively performing partial printing and sheet conveying. The printer includes a conveyer and a print head. The control device performs: acquiring an object image data representing an object image and additional image data representing an additional image added to the object image, where the additional image has a first length in an area; determining a position of the object image and a position of the additional image in the arrangement area such that the first length of the additional image at the position is minimized, where the first length is greater than or equal to zero.

  • Patent number: 10569543
    Abstract: In one example, a printhead assembly module includes an upstream row of printheads and a downstream row of printheads and a flow structure to distribute printing fluids to the printheads. The upstream and downstream rows of printheads are offset from one another such that a printhead in the upstream row extends past the downstream row at one end of the module and a printhead in the downstream row extends past the upstream row at the other end of the module. The flow structure includes a plate, slots in the plate to carry printing fluid to the printheads, and corresponding channels in the plate to distribute printing fluid to the slots. The slots and channels are arranged on the plate such that the arrangement is the same when rotated 180° about an axis of symmetry located at the geometric center of the arrangement.

  • Patent number: 10569579
    Abstract: A recording-head position adjustment mechanism includes a beam to suspend a recording head that discharges droplets so that the recording head is drawable out in a predetermined direction; a first supporter disposed at one end of the beam in the predetermined direction and having a support shaft to support the beam; a second supporter disposed at another end of the beam in the predetermined direction with the beam interposed between the first supporter and the second supporter. The second supporter is attached with an adjuster via which the second supporter supports the beam. The adjuster includes a coarse-adjustment shaft member and a fine-adjustment shaft member that are manually rotatable independent of each other. The coarse-adjustment shaft member coarsely adjusts a rotation angle of the beam at which the beam rotates around the support shaft by manual rotation. The fine-adjustment shaft member finely adjusts the rotation angle of the beam.
