There is a rather large disparity between the Graphic Arts
standard Illuminant D50, and the sort of lighting most
people use indoors. Even the higher quality 5000K Fluorescent
lights don't have a spectrum that much resembles D50, and the
Ultra Violet content of the lights is another wild card
when combined with Fluorescent Whitener Additive in paper
stock, since the UV output is often not closely controlled.
The closest practical lighting are filtered Quartz Halogen
lamps, such as Solux <http://www.solux.net/>, although I'm
not sure that the UV content is the same as real D50 daylight
(in fact they seem to boast that it has low UV output, making
them rather unsuitable for viewing substrates with FWA under
standard D50 conditions.)
