A method of selecting inks for use in imaging with an imaging apparatus includes establishing a high fidelity colorant cube having a plurality of vertex lines pertaining to a corresponding plurality of basic inks, and at least one other vertex line pertaining to at least one high fidelity ink; determining first mixing coordinates of the at least one high fidelity ink and the plurality of basic inks for face grids of the high fidelity colorant cube based on a maximum permitted ink amount; determining second mixing coordinates of the at least one high fidelity ink and the plurality of basic inks for interior grids of the high fidelity colorant cube based on the maximum permitted ink amount; and generating a color conversion lookup table based on the first mixing coordinates and the second mixing coordinates for printing with the imaging apparatus.
