Abstract (en)
This present invention is embodied in a printing system (100) for improving edge quality of ink drops produced by an inkjet printer (300). In general, the present invention can include an inkjet printhead assembly (116) that incorporates a preprogrammed correction scheme (212) for correcting systematic ink drop placement errors of the inkjet printhead (116). A general correction scheme (212) can be developed for a class of inkjet printhead assemblies during manufacturing of the class of inkjet printhead assemblies. The correction scheme (212) could include general corrections that cover general errors that exist for the entire class of inkjet printheads. Alternatively, individual correction schemes (212) can be developed during manufacturing of each inkjet printhead assembly (116) that covers specific errors that exists for each individual printhead. <IMAGE>
