ABSTRACT:
A method of printing is described for a page-width printer including a line head having a plurality of jetting modules that are staggered in a page-width direction. In a set up procedure, a test pattern is printed using the nozzles of adjacent jetting modules, and the pattern is analyzed to detect a stitch error in the overlap regions. The results of this analysis is used to calculate a set of correction values to be applied to print data subsequently sent to nozzles of the adjacent jetting modules to make a correction for the stitch error. During a subsequent production run, the print data sent to the nozzles of the adjacent jetting modules is analyzed to sense an image content attribute, such as gray or density level, of the print data. These results of the analysis of the print data is then used to calculate a dynamic adjustment that is used to adjust the set of correction values calculated during the set up procedure. The line head is then used to print the corrected print data by applying the set of adjusted correction values to production print data subsequently sent to the jetting modules.
