DEAR DIANE,
	Thanks for the thorough reply.  I have discovered that the best
ideas are combinations of those submitted by different parties often with
divergent interests.  So why not send John Horowy:
1) At least one example print showing your grainy results.
2) One print on the older COT 320 using the same neg showing the lack of
grain.
2) At least one sheet of the newer problem paper.
4) One sheet of the older COT 320 that does not exhibit grain.
*****Be sure to write the batch number in pencil on each item you send.  You
can find the batch numbers on the labels on the white envelopes in which the
COT 320 is packed.  With this evidence, you may well convince Bergger that
they have a problem, at least with that batch, and they may actually take
action to correct it.  No guarantees that they will, but they certainly will
*not* without having their noses stuck in the evidence while swatting them
on the butt with rolled up newspaper.  Oops, Cesar (Dog Whisperer) says we
can't use that training method any more.  Oh, well!
	But you get my drift...
		CHEERS!

Hey Bob,

I typically order COT320 from B&H in NYC.  They have been out of the size I
wanted for a while, so I ordered directly from the Bergger site
(distribution in Illinois, I think?)  It was an 11x14 packet.  So the "art
merchant" who sold it to me was, in fact, Bergger direct.  

I started using it maybe a week after receiving it.  In terms of humidity,
my studio has about the right amount of humidity (also in a humid climate
here, in NC-- though not as humid as Barbados, I'm sure!).  I used to have
to use a humidifier for all my papers, in the space I worked in before- but
not anymore in the studio I have now.

And, as mentioned before, I tried the same negative with various other
papers (Arches Platine and Revere, specifically)-- papers that had been
sitting in my studio for quite a while-- nearly a year-- and the prints with
same negative, same chemicals, printed in the same afternoon, etc were fine.
I did print on several pieces of the new COT320 paper, with the same
(grainy) result.  I also discovered an older piece of COT320 that I had left
over, in a flat file here-- printed on that, and it was fine.

So I do believe the new packet of paper has a problem. It's possible, of
course, this is an isolated incident, but since at least one other person
mentioned the same issue, I think not.  John had suggested that I send the
prints to him, and he would send to France for evaluation.  My thought is,
rather, he should send the remaining packet of paper to France, so they can
evaluate the paper that's in there.

At any rate, I did not humidify this new paper, simply because everything
else that's in my studio works fine, and I never have to do that.  I can try
that, though, and I'll let you know what happens.

Diana
