Abstract: By simulating the interference-generated image fine structures with a continuous-tone printer or a display, the image fine structures can be predicted as faithfully as can be achieved by high quality machines. This is done without sacrificing the advantages of the continuous-tone printer or display (i.e., convenience in handling and the low costs of materials and machine), while ensuring that moiré, line discontinuities, imperfections in straight lines and other image fine structures that may appear in a printed document are predicted on a hard or soft proof accurately and conveniently and within a short time. The intensity of moiré and other peculiar patterns that occur when simulating the image fine structures in a printed document can be freely adjusted in accordance with the type of the printing machine which is to be employed to produce the printed document. Pixel values of an original image are separated, processed, and subjected to weighted averaging with adjustable weights.

Abstract: The first principal object of the present invention is to provide a method of predicting and processing image fine structures which, by simulating the interference-generated image fine structures with a continuous-tone printer or a display, enables the image fine structures to be predicted as faithfully as can be achieved by high quality machines without sacrificing the advantages of the continuous-tone printer or display (i.e.
