1.5 is what I measure (after dry down) with Vuescan and a scanner (turn on
the "Prefs|Enable Density Display" option, hold the control key and hover
over a dark area of the print). For comparison I can easily get to 2.0 +/-
when I check the density of a 100 per cent black square printed on Premium
Glossy Photo Paper. I usually get around 17 steps on my stouffer tablet with
my VDB mix as well.

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?
