1. A method for printing a digital-array representation of an input image having pixels of a given bit depth, said method comprising the steps of:

  • providing at a printing system the input image to be printed;

    generating with an image pipeline module of the printing system a final processed form of the image having pixels of a reduced bit depth less than the given bit depth and compatible with tonal levels of the printing system bycalculating, for substantially each particular pixel in the digital array, an offset weighted average of neighboring-pixel interactions with the particular pixel, wherein different non-zero weights are assigned to at least some neighboring pixels; and

    using the offset weighted averages to develop the final processed form of the image; and

    printing the final processed form of the image with the printing system.
