This is the main feature of No-Color-Management. By turning off color management you want to ignore
whatever profile is embedded in the file. Usually step wedges are "untagged" to emphasize this.
In general for all the usual uses or step wedges -- QTR driver linearization or ICC profile creation --
you never want to convert or change the values in the wedge and they should be printed with NoColorMgmt.
(it doesn't actually harm to "assign" a profile but I think it can lead to confusion like this)

I have made three prints of step wedges, each with a different embedded profile:
-Grey Scale 2.2
-QTR Grey Lab
-untagged
All were printed separately with Print Tool, Color management turned off, using the same QTR b/w starter profile.
The 3 results measured with an i1pro turned out identical. The embedded profiles did not have any impact, how is this possible?
Thanks
