A method for constructing a look up table for characterizing a printing device, and a system therefore, wherein the look up table is an inverse look up table for obtaining for the printing device colorant value in a colorant space as a function of given color values in a color space (50), the method including: (a) selecting an axis (51) in the color space (50); (b) selecting a path (55) in the color space (50); (c) determining color separation values (75-79) in the colorant space for a plurality of points (56-60) on the path (55); (d) analyzing the color separation values (75-79) for a specific colorant (cc, cm, cy, ck, c); (e) determining a particular point (64) on the path (55) based on the analysis ; (f) projecting the particular point (64) on the axis (51), thus obtaining a projected point (84); adding the projected point (84); (f) adding the projected point (84) to the look up table as a sampling point. |
