Thanks, Howard. I´ve just ordered ColorMunki. Let´s see what I can accomplish with it.

But what I intend to do is to partition the inks in QTR, linearize the curve and print from QTR afterwards. Will I be able to read the printed inkseparation file that comes with QTR using ColorMunki? If not (probably because CM requires larger chevron-shaped patches), how can I produce an appropriate sized ink separation file in PS?
