Sorry, it's not clear from your description whether this sort of re-linearization
is in fact a calibration. Without knowing the technical details of what it
does (ie. eye-balling the source code), or doing some careful measurements,
it is hard to know for sure.
Whether it
works well enough is another story. As I've said repeatedly, it is useful in production
environments more than in proofing. I find that it works best at correcting bigger
swings in printer output than one usually encounters in a current proof printer like
the -800 or -900-seres Epsons. If the initial optimized state was very good, the relin
will tend to make things worse. How's that for a sales pitch?
It's poor. Our experience with the calibration system I wrote for Colorbus was
a lot more positive than that, even when applied to much more difficult
situations such as calibrating a color copier using its scanner (and yes,
these were used for moderately high quality proofing).
