Digital BW, The Print

At this point I don't think that the Ultrachrome black is the answer because
of its very limited paper compatibility.  Seems like a more interesting
option for a new variable tone set would be Cone's new museum black...but
we'll have to see how well that fades...and how the dmax varies across
papers...there there is the problem that its a cone product and VM is an MIS
product...big problem...and from what Cone has said...he has an exclusive on
that technology...but who knows.
