QTR-Quadtone RIP

The format to use the ICC create tool is the one of ProfileMaker. Fine.
I have created one just reading the Lab value in colorshop X and 
pasting the LAb in a model I had of a PM measured file.

Looking at the profile created, the kTrc is apparently mapping the 
values. Meanwhile, I found out the kTrc works based on XYZ values 
(which I did not paste).

Can anyone confirm the XYZ are due instead of the Lab.

Thanks.
