Abstract:
1. A method for processing image data for a color separation comprising: detecting cross-process edges in image values for objects in a color separation, a portion of the color separation to be printed by each printhead in a plurality of serially arranged printheads, each printhead in the plurality of serially arranged printheads that prints a portion of the color separation being configured to eject a same color of ink to print the color separation; detecting an operational mode in response to a detection of a first cross-process edge in the image values; mapping the image values corresponding to an object having the detected cross-process edge to only one printhead in the plurality of serially arranged printheads that eject the same color of ink in response to a first operational mode being detected; mapping the image values corresponding to the detected cross-process edge to only one printhead in the plurality of serially arranged printheads that eject the same color of ink and mapping an equal proportion of the image values remaining for the object having the detected cross-process edge to each printhead in the plurality of printheads that eject the same color of ink in response to a second operational mode being detected; mapping the image values corresponding to the detected cross-process edge to only one printhead in the plurality of serially arranged printheads that eject the same color of ink and mapping an equal proportion of a predetermined percentage of the image values remaining for the object having the detected cross-process edges to each printhead in the plurality of printheads that eject the same color of ink in response to a third operational mode being detected; and repeating the detection of the operational mode and the corresponding mapping for the detected operational mode for each cross-process edge detected in the image values until all cross-process edges in the image values have been detected.
