Abstract
A color input image comprising a plurality of pixels, each pixels encoded in RGB color space, is processed to convert the RGB pixels to another color space domain for printing the color input image. The number of colors within a cell of the input image is reduced. Each cell comprises an N×M array of pixels and the number of colors is reduced to a maximum of b source colors, wherein b is a positive integer equal to or greater than 2. Each of the resulting colors of each cell is calibrated to generate a printable color. The cells are then processed to convert the pixels of each cell into another color space, for example, to determine ink vectors, in another color space, for each calibrated color.
