  • Measuring separation of patterns, and use thereof for determining printer characteristics
    Patent number: 8462407
    Abstract: Disclosed are methods (900) and apparatuses (600) for determining a location of a graphical object (2220) printed onto a print medium (230), said graphical object comprising a plurality of object marks, the method comprising the steps of superposing a two-dimensional reference pattern (710) having a pre-defined degree of accuracy over the printed graphical object, the two-dimensional reference pattern comprising a plurality of pattern marks (770); scanning the superposed printed graphical object and reference pattern to produce a scanned image (2400); determining a location coordinate (2923) of the graphical object in the scanned image (2400); and refining the location coordinate dependent upon the scanned reference pattern to determine a reference pattern coordinate (2904?) associated with the location coordinate (2923). Also disclosed are methods (1800), apparatuses, and computer program products for determining a head size (420) of a print head (3110) of a printer (3100) using the aforementioned method.
