Abstract
Separation of a color into values for colorants in colorant space can be done easily when color correction and color separation are done in separate steps, where the color is defined as a set of values in a trajectory space, and trajectories include points for which ink behavior during color separation is known. Colorant values for the color are determined by interpolation using values of the color located in trajectory space, and known values and corresponding colorant values of the trajectory points. Trajectories are preferably color axes dividing the trajectory space into tetrahedral. Colorant values may be corrected using techniques such as colorant replacement or colorant splitting prior to color separation. The color separation process can be calibrated using a test target.
