QTR-Quadtone RIP

Hi Harry & John,

I originally posted this and thank you for your feedback. In thinking about the conversion 
to Grayscale from RGB I have stumbled upon another inquiry... Do we know what Source 
Space the grayscale QTR Calibration/Linearization files were created in.  I understand that 
we are not to color manage BUT Photoshop nevertheless always converts "Untagged" files 
to the Working Space on the fly.  This might require a separate post and would be good 
for all QTR members to know... Maybe I have missed something but I don't see where the 
documentation talks about the Source Space that the "Target Files" were created in. 
Knowing this is instrumental in creating a good CMS is it not? Your thought please...

Regards,

Cody
