1. A method for digital halftoning by predicting an appearance of a rendering by a printer of a digital halftone representation of a continuous-tone image, the method comprising: using a processor, calculating a predicted absorptance value of a dot of a rendered halftone of the digital halftone representation, the dot corresponding to a pixel of the digital halftone representation, wherein the predicted absorptance value is based on a configuration of pixel values of pixels in an immediate neighborhood of the pixel, and on a weighted contribution of a pixel value of each pixel in an outer neighborhood of the pixel; and, using the processor, creating a digital halftone for rendering by the printer.
