摘要： What is disclosed is a novel system and method for minimizing visual artifacts, such as ROS skew and laserbeam bow, in a brick-layer halftone structure. The present method involves determining a line pattern from ROS skew and laserbeam bow profiles which traverses through successive halftone cells displacing pixels along scanlines in the process direction. The amount of displacement is varied as a function of the cross-process location as determined by the line pattern. Pixels along scanlines are shifted in a direction defined by the error profiles. In each halftone cell within which the line pattern traverses, extra pixels (empty pixel spaces created in the halftone cell by the shifting operation) are filled with lost pixels (pixels bumped from the halftone cell during the shifting operation) such that overall density of the halftone cell is maintained. The lost pixels are buffered such that lost pixels are preserved.

摘要： In a digital printing apparatus, such as a xerographic or ink-jet printer, test marks, such as halftone patches or fiducial marks for image registration, are generated on demand. Coordinates of a desired location of the test mark within an imageable area (such as on a print sheet or on a photoreceptor), as well as a selection of the desired type of test mark, are entered through a user interface. Also entered is data about conditions under which image-quality tests using the test marks are to be performed. Information about the test mark and test conditions is retained as a small number of scalar values. The system enables test methods for a machine to be changed easily, and a basic set of system software can be readily applied to different types of printing hardware.
