I knew you'd say that! And no doubt correctly -- the expectation may
simply have been because among the many platinum printers (surely more
than carbon) *most* seem (at least from here) to follow or intend to
follow the "classic" tone scale...

As soon as heaven opens up my calendar and inserts X time for the purpose,
I intend to try pyro on lith. However, it's not likely to tell much about
pyro for gum as a "rule," because styles of gum printing are so
all-over-the-map.... I would hesitate to generalize from tests even with 3
or 4 approaches. Meanwhile, though, the "pyro" neg I REALLY want is one
will print a one-coat gum and, say, a VDB or long scale rich cyano from
the SAME NEGATIVE... (Tho probably the digital neg will do that with its
rapid-fire variations... in fact some captains of digital may have got
there already.)

Then maybe it's just as well they NEGLECTED TO PUT THAT INFO IN THE
CAPTION !!! Although now that you mention it, that explains why the border
around 1B is wide and rough, and the one around 1A is not a border but a
thin even edge. Anyway, thanks for fill-in.

I doubt exact color is expected -- and would also guess it's possible that
different issues got somewhat different color repro anyway...
