Hi Steve:
I have seen 3 definitions in ISO standards for backing: white, black, and
multiple sheets of the same paper stock. If the paper stock is identical
between two systems you are trying to match, there should be no problem
using any of the above. If you are doing absolute rendering for proofing on
different paper stocks or performing virtual proofing on a display, then you
will observe significant differences of appearance, particularly between
very thin and very thick paper stocks.
In our work with Matchprint Virtual, we have confirmed that the best result
occurs when a neutral gray backing is used such as Munsel N7 or N8. This is
actually pretty logical -- N7 or N8 is about a 50% neutral reflector and is
the color of every light booth I have ever seen -- never seen a light booth
that is black or white!
