  • Print medium for generating printhead alignment data
    Patent number: 11654674
    Abstract: A print medium having a calibration pattern printed thereon for generating alignment data for a printhead. The calibration pattern contains rows of spaced apart fiducials, each fiducial having a plurality of concentric shapes representing a Barker code.
    Type: Grant
    Filed: March 31, 2022
    Date of Patent: May 23, 2023
    Inventors: Nigel Hoschke, Rodney Hardy, Steven Parker
  • Method of printing using overlapping printhead segments
    Patent number: 11571914
    Abstract: A method of printing an image using a printing system including at least first and second overlapping printhead segments, the method includes the steps of: feeding media past the printhead segments along a media feed direction; determining an extent of wander of the media in a direction perpendicular to the media feed direction; selecting a stitching method based on the determined extent of wander; and printing the image using the first and second printhead segments. The printing step includes stitching the first and second printhead segments using the selected stitching method.

  • Method of generating alignment data for printheads
    Patent number: 11312126
    Abstract: A method of generating alignment data for a printhead. The method includes the steps of: printing a calibration pattern using the printhead, the calibration pattern including rows of spaced apart fiducials, each fiducial having a plurality of concentric shapes representing a code sequence; imaging the fiducials at a first resolution to generate imaged fiducials; cross-correlating a template fiducial with the imaged fiducials at a plurality of different displacement s relative to each imaged fiducial, the template fiducial having a configuration matching the imaged fiducials; determining a two-dimensional set of cross-correlation values for each imaged fiducial, each set of cross-correlation values indicating a center of a respective fiducial; and generating alignment data for the printhead using the sets of cross-correlation values.
