RE: VDB

I'm sure I can't get even close to 1.2 with one coat VDB (subjective
comment: didn't measure, don't have a densitometer). Your 1.5 is very close
to semi-matte RC paper max. density (which is around 1.6 IIRC)... If I were
getting such density I'd never bother with double coating. I have Stonehenge
paper sitting somewhere, will try it for VDB when I will have time...

Regards,
Loris.

I get densities around the 1.50 +/- (5-stops) by single coating VDB. This is
to matte Stonehenge paper, no sizing. I find this is DMAX enough. How high
could one expect densities to reach with VDB? 1.8!? Higher?! Surely paper is
a big factor?
