Hi,
In case anyone's interested in playing with it, I've just made a new
pre-release of GPLin.
This version uses the ink limiting method suggested by Graeme a few
weeks ago, evaluating the hue deviation that occurs as the paper becomes
saturated.
For the black channel, I measure dL* / dInput for the Cyan channel at
its ink limit, then find a corresponding dL* / dInput for the black
channel (after scaling to take into account the difference in L* range
for the two channels).
BTW, Graeme, are you any closer to defining a file format for
linearization curves, so that targen can take them into account and thus
be less conservative in terms of ink limit when sampling CMYK spaces?
If anyone's interested in taking a look, GPLin can be found here:

All the best,
