Maximum Chroma vs. Maximum Gamut

Hi All:

It seems logical that if a RIP is ink-restricted and linearized to provide maximum Chroma, that any additional ink would only add contaminants; and that any color of a primary that might result from adding more ink beyond this point, could be produced by just adding the contaminants.

However, I have found that a greater gamut is obtainable in the darker colors if more ink beyond max Chroma is added.

Is the CMM incapable of recognizing what colors can be created beyond those that fall within the direct range of the patches measured? Are there contaminant colors that exist in the primaries that are not able to be reproduced by the primaries? Or...?

Thanks,

Jim Reswick
