摘要： The present invention provides a method for processing color image data for printing on an inkjet printer to reduce intercolor bleeding in an image recorded on a receiving medium. The method receives a target pixel comprising multiple separation pixels, wherein each separation is associated with a separate color plane and has at least three states, a first state corresponding to depositing no ink drops, a second state corresponding to depositing one ink drop, and a third state corresponding to depositing more than one ink drop. The method further includes determining if the target pixel is within a black border region near a black/color interface or within a color border region near a black/color interface. If the target pixel is within a black border region, the method replaces the target pixel with a black border output pixel derived from a black pixel modification pattern identifying an arrangement of separation pixels to deposit approximately one drop for each pixel location in the black pixel modification pattern. Similarly, if the target pixel is within a color border region near a black/color interface, the method replaces the target pixel with a color border pixel derived from a color pixel modification pattern identifying an arrangement of separation pixels for each non-black color plane that deposits approximately one drop for each pixel location.

摘要： The present invention is directed to a method for differentially processing image types within a document image to enhance the quality of on an image on a receiving medium. In one aspect of the invention, the method begins by receiving document image data including one or more image regions. The method determines for each image region whether the region includes any image data corresponding to a first image type. The method then prints regions including image data corresponding to the first image type according to a first pixel management process and prints regions not including image data corresponding to the first image type according to a second pixel management process.

摘要： The present invention is directed to a method for processing color image data to reduce intercolor bleeding in an image printed on a receiving medium. The method begins with the receipt of a target pixel that includes a plurality of separation pixels corresponding to individual color planes, the color planes including a black plane and at least one non-black plane. The steps of the method further include determining if the target pixel is within an black border region near a black/color interface, and if so, modifying the target pixel using a substitution operation according to a black pixel modification pattern, the black pixel modification pattern identifying separation pixels in the black plane to replace with separation pixels from a non-black plane; and determining if the target pixel is within a color border region near a black/color interface, and if so, modifying the target pixel using a thinning operation according to a color pixel modification pattern, the color pixel modification pattern identifying a pattern of separation pixels in a non-black plane to remove from the composite image.

摘要： The present invention is a method for processing color image data to determine if a target pixel is within a border region near an interface. The method begins with the identification of a target pixel within the color image data and then determines if the target pixel is a black or a color pixel. If the target pixel is a black pixel, the method collects a first set of pixel statistics from a first window comprising the target pixel and pixels surrounding the target pixel and analyzes the first set of statistics to determine if the target pixel is within an N-pixel wide black border region near an interface. If the target pixel is a color pixel, the method collects a second set of pixel statistics from a second window comprising the target pixel and pixels surrounding the target pixel and analyzes the second set of statistics to determine if the target pixel is within an M-pixel wide color border region near an interface.

摘要： The present invention provides a method of processing color image data for printing on an inkjet printer to maintain edge quality in an image recorded on a receiving medium. The method begins with the receipt of color image data comprising a plurality of color planes that combine to form an array of composite pixels, the color planes including at least one black plane and at least one non-black plane, wherein each color plane comprises an array of separation pixels, each separation pixel having at least two states, a first state corresponding to depositing no ink at an image location and a second state corresponding to depositing ink at an image location. The method then identifies an interface between an black area and a non-printed area; defines an N-pixel wide border within the black area; and modifies the color image data corresponding to the N-pixel wide border to reduce the number of second state separation pixels in a non-black plane.

摘要： An apparatus and method for forming an image with fluids having different firing velocities from a bi-directional print head results in a reduction in bi-directional misalignment error. The bi-directional misalignment error is reduced by delaying the firing of a drop of the higher velocity fluid on the return swath of the print head.
