Abstract: Disclosed herein is a method and system for determining a billing structure for outputting documents using an image processing apparatus. If image data of the document includes color pixels, a billing structure is determined for each page based on an amount of color coverage. The marked color pixel locations of the image data to be output in the device dependent space are counted. Each color pixel location comprises at least one color plane. In some cases, a ratio of the count of the marked color pixel locations to a maximum number of pixel locations may be used to determine the amount on the page. Processing and determining a billing structure based on image data in the device dependent space, irrespective of the amount of ink/toner or color planes used, avoids charging a customer for color print job when only a small amount of color pixels are printed.

Abstract: A method and system feeds a sheet through a media path in a process direction. When the sheet is within a sheet registration carriage of the media path, the method and system align the sheet to a predetermined lateral position within the media path. The aligning process comprises unevenly activating nips within the sheet registration carriage and moving the sheet registration carriage in a lateral direction perpendicular to the process direction. When the sheet is within the sheet registration carriage, the method and system determine a lateral movement distance the sheet registration carriage will move in the lateral direction during the aligning of the sheet. If the lateral movement distance exceeds a predetermined distance, the method and system move the sheet registration carriage toward the starting position after the nips have released the sheet, but before the sheet has passed by the nips.

Abstract: What is disclosed is a novel system and method for color trapping on halftoned bi-level bitmaps. Color edges are detected and edge pixels that need to be trapped are identified. The number of pixels qualified as edge pixels eligible for color trapping can be up to a pre-determined number of pixels away from the color edge. Estimates for the continuous-tone values are obtained for the dominant colors on each side of the two-color edge. The contone value of the dominant color on the opposing side of the two-color edge is assigned to the qualified edge pixels. Qualified edge pixels are re-halftoned using their assigned contone value so that halftones for one color are extended beyond the edge into the other color. The re-halftoned edge pixels are combined with the original bitmap to produce a new bitmap for the image. The new bitmap is then provided to an image output device.
