Abstract:
In a system capable of digitizing a continuous tone color image, a method of reproducing the color image on a media while controlling an amount of ink that is placed on the media, the method comprising steps for:creating an input file of digital image data containing information corresponding to density and placement of the colors for each pixel contained in said image; determining one or more levels for each pixel of the digital image data, wherein each of the one or more levels includes one or more sub-levels and each of the one or more levels includes a level limit; converting the digital image data into multi-level color values with level limiting such that the multi-level color values correspond to the one or more sub-levels of each level that are below the level limit of each level, wherein the multi-level color values that correspond to sub-levels of each level that are above the level limit of each level are ignored; digitally processing said multi-level color values so as to initially derive therefrom output values of each pixel; and preparing from said output values a color image.
