摘要： 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.

摘要： An ink delivery system for an inkjet printer includes: a positive ink line having a controlled positive ink pressure; a negative ink line having a controlled negative ink pressure; one or more print modules interconnected between the positive ink line and the negative ink line via respective inlet and outlet lines. Each print module includes: a printhead; a control valve positioned at an inlet port of the print module for controlling an ink pressure in the printhead; an ink pressure sensor for sensing an ink pressure in the print module; and a controller for receiving feedback from the pressure sensor and controlling the control valve. During printing, the ink pressure sensor, the controller and the control valve cooperate to control a backpressure in the printhead within a predetermined backpressure range.
