ANSI CGATS standards suggest that you back printed matter with black for
densitometery.
Most people doing color management use several sheets of the same paper
when doing colorimetery.

Hi to all,
I'm trying to match a proofer and paper to the FOGRA mediawedge.
The rule is that the proofer paper has to match within a range of
deltaE 3 to the press paper, which is european sheetfed coated.
Now here is the problem: It seems that the white backing of the DTP41
is not white enough:
If I measure normally (e.g only the paper sample), deltaE is about 3.6.
If I measure with another blank sheet of the paper underlaying, deltaE
is about 2.6.
Has anyone else seen this, or is my DTP41 simply dying?
Rolf
