Very nice idea if the output device would never drift. Which is never the case.
The normal drift over time of any inkjet printer (which is actually a
compound of device drifts, plus ink and media batch tolerances), would
introduce an error that would render this procedure less accurate than
just generating a standard profile of a thousand patches or so.
My guess.
