Yes, this confused me too. I made several curves for Pd/Pt and carbon by changing the total ink load to correspond to my blocking density. They worked ok, but, I noticed I was getting star wheel?marks (P900) especially in my negatives for carbon (K45). I decided this was because the ink load was too heavy. When I re-did the curves by making black boost equal the blocking?density, the overall ink on the paper seemed to be considerably less and the star wheel marks disappeared. Also, the linearization was much better. Also, changing the black boost appears to replicate more closely the workflow?in QCDN version 2. I do not have extensive experience with linearization, but that is my recent observation.?

In my case I can up with a blocking density of 35 (see attached
screen capture).
I am applying the Blocking Density number by manipulating the "Total
Ink Load" slider on the Starter Curve Setup page as on the attached
screenshot.? This worked for me, but I am not precisely sure if this
was the planned use.? Another individual told me to use
100-(Blocking Density) as goal for the "Maximum Black Percentage"?
which threw me way off course.
