Personally, as a non-color-scientist, I suspect that chroma-based
linearization is the way to go, because I have seen density-based procedures
go too far and end up cutting some of the available saturation in the output
(specially the procedures that are based on visual evaluation, as opposed to
measurement-based).
Whereas it would seem to me that limiting the ink at the point just before
one starts to detect a decrease in chroma would guarantee the highest
saturation achievable in a given device. That way, the device will perform
at the peak of its color gamut while avoiding the pitfalls of excessive ink
amounts (first and foremost being the tortured profiles that usually
result).
I would be interested in hearing the opinion of other colleagues.
Regards.
