I've never quite understood the theory (even when I asked them specificly)
about how Profiler deals with the black generation functions. In other
software I would look at Under Color Addition as a tool to control this, but
in Profiler, this is a fixed function controlled by other settings, not an
adjustable variable. Since an actual black curve can not be sculpted, I
don't see how the available controls for ink limits and UCR/GCR can control
the curves to the degree you desire. Nor am I familiar with any advantage
that this fluxuation would offer.
