Abstract: For a selected class of functions, which describe most typical banding variations, the average response can be found by sampling at only 2Nth locations, where N is the number of different frequencies of significant banding. This approach makes use of the fact that in most applications the banding frequencies of a given printer system, are known in advance, even if the amplitudes of the banding are not known. Each sample point requires a very small test area or pattern, significantly reducing the overall size of the required test areas.

Abstract: An approach is provided for generating a printing member. The approach involves determining one or more image areas associated with printing one or more images, the one or more image areas being positioned on a surface of a substrate. The approach also involves determining a liquid interaction behavior of at least the surface of substrate is one of hydrophobic or hydrophilic. The approach further involves causing, at least in part, a substance that is the other of the determined liquid interaction behavior of the surface of the substrate to be applied to the one or more image areas on the surface of the substrate by a jetting process. In one embodiment, the printing member is mounted inside a printing system when the substance is applied. In one embodiment, the surface may be completely or partially cleaned and a new image created by another application of the substance.

Abstract: A printing system and method is provided including a printer having an print marking means for printing a printer-ready document, including transferring or applying an image associated with the printer-ready document to a substrate; and a processor assembly in operative communication with the printer. The processor assembly executes application software for receiving a print job request including the printer-ready document. The processor assembly includes a module for accessing print defect data indicating location and color separation information on the print marking means which corresponds to a detected print defect; and a module for modifying the printing in accordance with the print defect data for minimizing visibility of the detected print defect in the printer-ready document once printed.
