Criss Hartzell,
When I switched to this method my linearization was very quick and
when scanning the 51 step step-wedge with my i1 Pro I ended up
exactly following the green line in the linearization.
I have emailed Richard twice about this, but so far no reply.?
Perhaps he will answer here.

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.?

If anyone out there is using the newest version of
QuadToneProfiler-QuickCurve DN (version 3.1.3) by Richard
Boutwell? ? I am wondering exactly where you are supposed to
enter the Blocking Density from the blocking density test.?
His instructions gloss over specifics.?
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.
