with the same MaxK setting escapes me a bit. MaxK is MaxK, no? Thanks,

That result doesn't
surprise me. While I don't know the algorithmic innards of PM, I would expect
that
by lowering the TAC
there is also a shortening of the tonal range of the Neutral Axis, i.e. the
min-L*
increases. Yet
at this new black point (at lower TAC) the same max K value is expected to
be
hit.
Therefore, if one assumes the start point of K is the same tonally, then if you
shift the L*
end point and at the
same K (in this sense the L* is on the X-axis with Y-axis being % K),
then
the slopes of K
generation will differ at the 2 different TACs. Hence, the difference in
CMY gen
at overlapping
L*'s.
