trust your eyes (after first being very sure what your eyes are
actually telling you).
The post explains the conditions under which one's eyes can be
trusted. This procedure has been posted many many times through the
past three years or so.
In this case the user is altering the white point of the
output/simulation profile. The user should be altering the white
point of the destination profile. Previous posts have explained which
channels in the destination profile should be altered : the a* and b*
channels, but not the L* channel.
If the L* channel is raised, and if the proofing medium is already
brighter than the output medium, the result is somewhat similar to a
relative colorimetric match, meaning that there is no white point
simulation.
If there is no media white point simulation, then for many users the
proof looks better than a proof with media white point simulation.
The user should indeed trust the instrument and the software first of
all. As with media black point simulation, the instrument tells the
true story. All the tweaking and tuning, that is a fallback
procedure. But you are right that a Measuring ABC should be posted.
