Tom,
I don't have data to show (not yet, at least) but I always was under the,
wrong perhaps, impression that the single most disadvantage of tungsten
lighting, relative to D50, was its low UV content. Yet, you write that
typical "graphic arts" fluorescent lamps (aka viewing booths) seem to
exhibit the same low UV energy content as "properly adjusted lamps".
How is that possible?
Roger

Claas
Physically speaking, the tungsten output of a lamp is well understood and
the amount of uv in a properly adjusted lamp is extremely consistent between
instruments of any family. Most importantly, the excitation from an M0
instrument generally excites the OBA in the paper more than most viewing
booths. If anyone took the time to actually measure the UV excitance of M0
instruments using a certified tile with OBA, they would have seen that there
is excellent agreement between instruments.
Regards,
Tom
