I understand why you would want to have PK in the printer but not so 
much why you would want to use it in curves for matt paper when it's 
density is so close to the LK. I can see though that it does have 
benefits in a more neutral curve and I understand your arguments against 
using a LLLK. I presume you would not have any concerns about any 
interaction between Eboni & PK in the same print.

Yes, I hadn't noticed that before as I more often use .acv curves. The 
second preview point curve seems to show points from the first and 
second curves.
