Digital BW, The Print

Paul, I'm still perfecting things, and each paper so far is different
and requires different ink percents, different GO in the go down, and
different GO overprint. In fact, it may not be absolutely perfect by
the time the samples go out. I'll think I've nailed it, then a
different image will show some little problem.
This is a major reason for the samples- feedback to see if I should
proceed.

Needless to say, my dmax will be nothing near the 3+ you have
reported. But of course I'm juggling more grays.

I'm not seeing roller markes here, but wonder about the mechanics of
these different printers.

By far, to my biased eye, the most beautiful prints coming out of here
for people are the matte prints. Not all of them, but some just
succeed in a way the gloss does not, that elusive something extra.
The other beautiful prints around here- Silver gelatin.
