QTR-Quadtone RIP

I’m having trouble wrapping my brain around selecting Limits and Densities and other settings to create a Profile for a Digital Negative for Silver Gelatin.
Using a P800 and printing the inkseparation file  and the SG readings are:
PK gives white at 55
Magenta gives white at 80
Note Yellow no blocking for tungsten light.
LK Ink almost blocks at 100
Other inks no blocking 
Now what numbers, etc do I put in QTR Curve Creator? I’m on a PC.

Thanks
Terry Glass
