Hi,
please keep in mind, that there is a large difference in perception between
a reflective D50 illuminated area and what gets out of a transmissive
display at 5.000k (even if these 5.000k are very close to the black body
curve or even if the whitepoint match the D50 xy values).
In some cases to match Papertype 1 with ISOcoatedv2 a display´s whitepoint
that is much colder than D50 or CCT 5.000K is needed (between 5.600 and
6.000). There has been some research about the question which whitepoint
matches which papertype best at the RIT and there will be a research program
at the swiss ugra about that topic soon.
Based on my experience, adjust your display´s whitepoint to a value that
matches perfectly to the paper that want to use under stable condition
(follow ISO3664´s recommendations about the lighting).
The fogra has a softproofing handbook for free on their webpages that may
helps in this respect, too. (www.fogra.org)
