Good to hear someone else is having success. I'm curious what you mean by "Once I started spraying it well and brushing the surface""

I grab a spray bottle of distilled water and give it a couple of good squirts from an altitude of about two feet. The water beads on the surface. I brush it back and forth across the paper three or four times, then wait until surface is not wet to the touch....just a couple of minutes...and coat with a brush. I'm using 20-25 drops on an 8x10, and it takes lots of brushing to get it into the paper. Have had none of the previously described issues since. Maybe I have a good batch. Maybe this just works. What are you doing to it?

I was talking with David Pitcher after our group meeting last month and he said he is using this paper. He also is pretreating the paper in a manner very much like John. David said that since he began doing this he has had no problems and strongly recommends Revere Platinum. I haven't purchased any of it yet; after the reports of problems began appearing I decided not to. Now that I am hearing good things about it again, I am thinking I should give it a try.

Please try it!

This is a really lovely paper. Get the heavy one. There are two weights. Bostick and Sullivan sells it in 11x15 in small packages as well as full sheets...Get a few sheets and try it. Caveat...it does take a long time to coat...I use a brush. If your friend knows how to get it to take up the coating more quickly, I am all ears!

I have absolutely no problem coating the paper with a brush -- it coats as quickly and easily for me as COT320 and Platine. Nothing I do gets rid of the blotchy sizing though. Gee, I hope if the mill tweaks the paper manufacture they share this info, else we will could be talking about different versions of the same paper.

Either there are two different batches or we're doing something differently that we haven't thoufht to mention. Philip I assume you've tried something like my spray and brush? My theory is that the brushing smoothes out bumps of uneven sizing.

John, I don't recall him mentioning anything unusual about the coating time. Our group meets again next week. If David is there I will ask him about it and get back to you.

Yes, see my previous posts.
Re bumps of uneven sizing: I see internal blotchiness -- it is not on the surface of the paper.

developed in Potassium Oxalate,
my clearing method, oxalic acid followed by 3x 5minutes in sulfite + metabisulfite


perhaps my first water bath is'nt enough acid, between developer and oxalic acid?
or paper must be acidified before

thanks

Clearing Revere Platinum

I give 5 min water wash after dev in K oxalate, withh several dump and refills. Clearing 5 min each in citric acid and 2 baths of EDTA plus Na sulfite. No problem. How are you coating?

10 OF / 9 PD /1 PT with brush

Edta will be better than metabisulfite for this paper?

Don't know. I clear most all papers this way. Haven't tried anything else. David Kennedy and Kerik Kouklis have used the paper extensively. Might be worth a couple of emails to find out how they are clearing. Are you pre treating with water or using tween? This papee is not very thirsty to me. But I like it very much.

My 2 cents on clearing this paper...What has been working for me is first bath 5 min EDTA and sodium sulfite 2:1 respectively, and 2 additional baths strait EDTA. By half way through wash tray # 2 its clear.

I finally had a chance today to do some printing on the Revere Platinum. I bought 20 sheets of each weight from B&S a few weeks ago, and I jumped in to do some tests today. This is all fresh chemistry (including the developer). Bottom line:

I am seeing some odd irregularities in the dark tones on the heavy Revere. I printed the same exact negative on a piece of COT320 and scanned both prints. You can see the streaks running diagonally from upper left to lower right on the Revere Platinum here (I have put some red lines and arrows so you can see what I am talking about:
revere.jpg

A closeup scan of the same area of the print on COT320 here:

cot320.jpg

The irregularities on the Revere are small but noticeable. I wouldn't let this print out the door.

My coating procedure for both was to coat using a Richeson synthetic fiber brush and air dry under a cool fan to an ambient humidity of 32%. A test strip determined that I needed to increase the exposure on the Revere from 255 units to 300 units on my Amergraph ULF28. They were both developed in fresh potassium oxalate at 120 degrees. Both papers have been sitting out and getting acclimated for a week to my darkroom conditions.

I did not notice the irregularities during the coating process that others are reporting, but the final print does exhibit some unevenness. It might not be noticeable in a busy image, but any large continuous expanses of tone such as the sky seem to show this pattern. Also, the Dmax I got for both papers was identical: 1.4.

I think this paper has a lot of promise if we can get these apparent sizing irregularities ironed out.

i have these irregularities, i think the paper doesn't absorb the solution very well.
Perhaps we must dampen the paper before like John Sarsgard do

Gee, I have an idea -- Magnani should fix the sizing, or at least publish the specific requirements for getting consistent results with this paper.

I agree with Philip...although I haven't used this paper, if it's so problematic and/or inconsistent it's time to move on.

I have given up with this paper for the moment, have about 50 sheets of it just sitting gathering dust that i am not prepared to waste chemistry on. Magnani have gone very quiet, despite repeatedly asking some quite simple questions.

EDTA by itself is not a good clearing agent for any paper.
