Abstract: PROBLEM TO BE SOLVED: To achieve printing at a high throughput on a print media substrate differing in substrate attribute. SOLUTION: A printing system 40 includes a plurality of marking engines 10 and the like so that a group of images of a common print job stream can be printed on plural types of print media different in medium attribute. An image to be printed on a medium selected as a medium for printing is identified on a medium selected by a processor 133 for processing the print job stream. A planner/scheduler 56 is in communication with the processor 133 for selecting a marking engine (e.g. 10) to print the identified image on the selected print medium. An actuator modifies an operating parameter of the marking engines to a set point. A processing component 58 sends information on the identified image to be printed to the marking engine for forming a complete image on the print medium. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To compensate a streak defect in an image formed by an image forming device. SOLUTION: A compensation pattern including a plurality of gray level portions and a plurality of fiducial marks is used. Each of the gray level portions 412 to 418 has a gray level different from the other gray level portions and extends along the cross-process direction, and are spaced form each other along the process direction 440 such that a gap is provided between each pair of adjacent gray level portions. The fiducial marks 430 are arranged before (431) and after (433) the plurality of gray level portions 412 to 418 along the process direction 440. The compensation pattern is used for determining a difference between an actual gray level and an intended gray level at a cross-process-direction image-forming device pixel location in the image.
