Abstract
The disclosure describes methods for color printing, performing a color separation process and performing a halftoning process. Furthermore, the disclosure describes the color separation process determining one or more Neugebauer Primaries, tessellating the Neugebauer Primaries, and generating one or more Neugebauer Primary area coverage vectors, whose area coverages are linear with respect to a device-independent color space. The disclosure further describes that the color separation process communicates with the halftoning process using one or more Neugebauer Primary area coverage vectors.
