QTR-Quadtone RIP

i've completed the ink partitioning and created the quad curve file. 

now i'm ready for the correction curve process. 

per QTR's Eye-One-ReadMe.pdf (pg. 4) it instructs creating the quad curve and print the 
Step-21-gray stepwedge. but before i print the Step-21-gray stepwedge to create a 
correction curve, am i suppose to follow the printing procedure described on page 6 of 
Tutorial.pdf -- that is selecting Let Photoshop Determine Colors, QTR-Gray Matte Paper, 
Rendering, and Black Point Compensation before printing Step-21-gray stepwedge? if not, 
then should it be No Color Management or Printer Manages Color?

a bit confused here.

your help is appreciated.

thanks.
