Digital BW, The Print

Deep black today, no black tomorrow, is no black at all in the Cone
book...and mine too.  I would encourage you to look at coating possiblities
with the Piezo or other pigmented inks.  Piezo inks on some "unapproved"
papers like the Kodak Ultima Satin or Prophoto Silk are as good or better
than any dye system on gloss papers when simply sprayed with a light coat of
krylon to seal the pigment.  If you want archival...then as I mentioned
previously use an archival paper with pigmented inks and a couple coats of
an acrylic clear coat...once again the blacks come raging in.
