The color of the paper is the color of the paper. It will vary depending
on the color of the paper. The white of the screen doesn't vary. If
you're printing to grey stock. It's grey not white.
You just gotta' do tests. Generally I use stuff that's slightly
yellowish like BFK. I think it's just something you learn to accept or
to correct for. I use BFK or Fabriano because I like them. If I were
going for accuracy I'd go for some sort of ultra white mylar or
something. You can get *white* papers if you look for them.

I think we're just looking at the same thing from different
perspectives. I think you just need to learn to work with a particular
paper... to use it for it's inherent qualities. I don't look for a
perfect copy of what's on the screen I look at the final product.
