Abstract
A system and method for color image reproduction prepared from random fixed size dot placement. In one embodiment, a color image is digitized using a scanner or other input device to prepare a red, green, blue (RGB) data file which is input to a central processing unit (CPU). The RGB data file is converted to corresponding standard process color files of cyan, magenta, yellow and black (CMYK). The CMYK color files are then digitally processed by the CPU using an error diffusion method to generate data files containing representations for each of the CMYK process colors wherein the representations correspond to random fixed size dot representations containing information corresponding to color density and placement for each pixel of the color image. Color separation prints can then be output which can than be aligned and used to print a composite color image reproduction.
