It derives from a profile a new one that does indeed completely
desaturate to what it determines to be the device's neutral axis. With
RGB profiles that seems to be pretty straightforward. With CMYK
profiles, it seems to leave K approximately where it was, it does not
generate a "MaxK". So the rest is made of CMY, supposedly in a neutral
fashion. Total ink was almost identical, the K channel very slightly
different, black point had very nearly identical CMY values as the
original, K dropped a bit. But K start point and curve seemed very
similar. A MaxK profile sent to it remained MaxK. Any file sent to it is
converted to this "neutral" build, all colors desaturated. After
conversion you can alter color of course, since the color ink is there.
That's as far as I got with it, for what it's worth.
Whether or not it prints with more neutrality then a gray file sent to
the original profile, I haven't yet tested. If it does, I guess that
would be it's value. Seems like it could be a useful tool, but not very
related to what one might normally call "rich black". Maybe it might
have more application outside my world of inkjet printing?

As Andrew replied, X-Rite's ColorShop X has as one of its features, an app called
Rich Black.

I would love to know more about the value of this tool.
