Re: Cot 320

On the upside, I just finished coating, exposing, and developing an image on a piece of 16x20 [new] batch I have, and it turned out fine.  That's one sample-- but better news than what I had been experiencing . . .  On this one particular piece, I noticed no beading and no graininess.  And the image is from a toy camera negative-- so certainly not the most perfect negative in the world, and it really turned out very nice.  So maybe this is a good sign?

Well, this news really stinks.

I guess it is like Dick Arentz says, any change in papers is always for the worse when it comes to pt/pd printing.

I also noticed the graininess-especially in the pure blacks.  It was more pronounced where the coating was thinner along the edges of the paper.

Hi Mark,

Yes,  I was just printing with some COT320 paper last week, and I wondered if they-- like everybody else-- had somehow changed the make-up of the paper.  I usually order it from 2 different places-- depending on who has it-- although it should all originate from the same central place (right?)-- but, yes, I did notice a difference.  I have some bigger paper that I haven't opened and was going to try that today to see if there was a difference.  I was using a batch of 11x14 before.  I had to keep brushing over the same spots to get over the beading/  I also noticed that  I was getting this grainy look which I had never before seen with that paper.  I switched to a brand new brush, a brand new tray, and I even made up some new developer-- wondering if one or the other had been contaminated in some way.  I was also using negatives I'd used before-- with no problem-- and still, I got this graininess.  I'm hoping that doesn't happen with this different size-- and was thinking I just got  bad batch or something-- who knows.  I do wish paper/film manufacturers would simply leave a good thing alone.  Too much to ask, I guess.
