ABSTRACT:
A method and system are provided to perform digital printing using error diffusion but without the usual problems of the anisotropy associated with that method. The method computes several error diffused digital images on a variety of rasters, and averages them with some chosen set of weights. The method works directly for printers with more than two choices per color per pixel, and can be implemented by defining super-pixels, even with the simpler printers that have only white and black or two color value per color coordinate.
