You can use Colormunki's Photo Color Picker application to take LAB spot 
readings of the ink separation print or the 21-step wedge. The patches 
are big enough if you're careful. It's painfully laborious but the only 
way I've found.

(If anyone does know a way to automate the process with the Colormunki 
I'd like to hear it. I'm still using my old 810 with X-Key and Excel for 
this - it's far quicker.)

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?
