If, after using this process, you still need to tweak the monitor to match
different stocks, then one or more of your printer profiles must have a
white point error in its forward tag or an erroneous white point tag. This
is most often caused by not using a UV filter in the measuring device. The
ideal solution is to identify which printer profile is wrong (assuming only
one is) and correct it in profile editing software.
Perhaps it has been mentioned before, if so please feel free to ignore this
mail. In matters of optical brighteners and the use of UV filters I see
something in addition: If filters are used to measure colors on paper with
optical brighteners the colors and the paper behave as if there are no
optical brighteners involved. But in reality, they are still there.
Therefore, the proof in the lightbox looks brighter than it would look
without OB. So I think it is necessary to tweak the monitor to a higher
temperature if OB are involved. But what leads to better results: doing this
before or after making the monitorprofile?
