The temperature in a standard is a arbitrary point agreed upon to make a
concise starting point that can be referenced to. The reality of viewing
conditions is rather uncontrolled even in willfully good installations.
Rarely do 5000 K light boxes make a measured white point of 5000 K and or
D50 viewing, as not only the white point but the CRI (colors produced
through the spectrum) will have much different characteristics than another
light source.
What a photographer needs is a reliable proofing/soft proofing set up. This
means putting up the most used medias into the viewing conditions and
comparing not only white but a printed test image (s) with the same on
screen. Some profilers let you change the white point on the fly, others let
you change the white via gain controls and offer temperature feedback to let
you know when visually you match what your eyes see on the print and the
monitor at the same time. Oh, I should qualify that the image on screen
should be a normalized working space.
More often than not Apple computers and CRT's match up well at around
5300-5800 @ G2,1-2,4 to inkjet papers mild optical brighteners in Just
Normlicht, Gretag boxes, or other such as GTI. LCD calibration is still
works in progress, but it looks like a little higher temperature than CRT's
match up well. So try out something around 5500-5700 and see if it matches
your paper.
No doubt there will be more detailed info in Bruce Fraser and Chris Murphy's
book on Color Managed workflows.
