On the other hand, if you do prepress work -- using a color-correct

will also need to be strictly controlled (dark neutral walls, dark
clothing,
no reflections, etc.)
Actually, if you are doing soft-proofing and you are putting a light
booth next to the monitor to compare a hardcopy proof to the screen,
the screen has to be pretty bright, usually in the 140-160cd/m2 range.
A monitor set to 80-100 will look too dark compared to a light booth,
even if you dim the light booth all the way down. At 140-160, the
booth will be at about 40-50% brightness.
All the certified soft proofing systems listed at http://www.swop.org/certification/monitorList.asp
have a target luminance of 160cd/m2 on the application data sheets.
I was under the impression that the lower "recommended" values (80-100
cd/m2) were partly the result of legacy values from the days of CRT
and partly recommended to extend the life of the back-light as long as
possible. In most "real-world" prepress departments, anything below
140 is going to be too dim.
