"New" Paper for Platinum/Palladium

[TheFlyingCamera]

Yet another vote for the "magic" brush. It's terrific for just about any paper. I'm finding that with COT 320, I can get a nice even coat with good dmax for an 8x10 with only 14 drops of sensitizer. Seven for a 5x7, maybe six if I'm very careful. I've had to go with 20+ drops for an 8x10 on some other papers, or when using a rod.

I started testing my samples today. SInce most seem to be using the paper for platinum/palladium I promised John I would try it for some other processes.

Humidity was ranging from 12-15% so I turned on my circulating water bath at 110 deg. to raise it. The paper was laid on a screen over this water bath for a minimum of 30 minutes prior to printing. I know this is not very scientific, but my hygrometer is broken so I just have to estimate the RH by feeling the paper.

This morning it was Van Dyke Brown. For this process, the printing time is very similar to Platinotype. It clears very quickly in the wash-off development and produces a beautiful deep chocolate brown. I have not toned one yet, but will do so this afternoon.

The color is a little more yellow than I am used to, but certainly not objectionable for this process. The wet strength is excellent for such a light weight paper.

I am looking forward to seeing the results of other processes on it.

has anyone tested the dimensional stability of the paper? this is thinking towards using it (or the hopeful white version) as a gum over pd/pt substrate.

Non!! Shrinks too much and not the same in each dimension. But it is a nice straight pt/pd paper..

Thanks for the heads up, Clay. If they make a white version of this paper it will be nice to have a warm-toned paper, a white, and also a white paper for gum over (FAEW) all under $2/sheet!

Is one coat enough to print beautifully? Sounds like saving on pt/pd drops, if so. Thanks.

 

[buze]

How to you get this paper? is it still "sample" only or is it available to buy ? I'm currently printing on (the back of) Canson Sketch, but I'd like to experiment...

 

[Kerik]

Eggshell - one coat will do it.

Buze - see the beginning of the thread...

I'm in Canada and had no problems placing an order directly with John Zokowski @ 800-634-7070 ext.5100. He accepts MC/Visa/Amex and ships 'worldwide'. A wonderful fellow to talk to!

Really nice stuff. Looking forward to the white version.

i just uploaded in my APUG gallery a print I made on that paper. It's a really nice one.
Just have to take care to it when wet. Sharper and better highlights than Crane Cover. Warmer than Arches Platine with Potassium Oxalate at normal temperature (68°F). Very thin and so very suitable for artist book with original prints in it.
Scan quality is far from original print.

The new found Westons paper is wonderful!

I have been printing for the past three days on it and am love'n it!

My thanks to the photographer who worked with John to discover this fine material. And, of course, my many thanks to John for making it available for sale.

It looks like the Cot 320 will be sitting unused for a very long time to come...

Well, I don't think you should treat such a nice paper that way! I'll do my part and save this relegated 100% cotton rag from your drawers... I'll even chip in to help with the shipping cost

I posted a traditional cyanotype using the Weston Diploma Parchment in the technical gallery. Great for cyanotypes- coats easily, clears easily, long tonal range, sharp image boundaries, fine D-max.

Incidentally - calling does seem to be the good idea - I sent him email weeks ago and never heard a thing back.

I don't know if this has already been covered. But does this paper bleed (or leech) around the edges like the old platinotype did? Or is it possible to mask the edges and get a nice sharp edge without the bleeding? I'm referring to Pt/Pd printing. Thanks

 

[cperez]

I haven't seen any bleeding. The edges are nice and sharp. Well, at least thus far they have been.

I discovered something else that's kind of neat. Cot 320 makes great fire starter. Better than burning newspapers to get the furnace roaring. [just kidding, it's a fine paper, really, I mean it... ]

[Dana Sullivan]

Bleeding is caused by the reticulation of the surface sizing. You can generally fix the bleeding problem by doing a pre-coat of distilled water, or 1% oxalic acid solution. This will homogenize the surface and keep your emulsion from bleeding to other parts of the paper as it dries.

Has anyone done any Kallitypes with this paper?

Just as soon as things slow down after the holidays, I am going to make an Argyrotype on it (Dead Link Removed updated version of a Kallitype). I'll scan to post here and I will also be sending one to John.

 

[Jeremy]

Printed some pt/pd on the Weston paper and they look really good. The paper is much thinner than I am used to working with, but there were no problems.

 

[donbga]

I just made two test prints and the paper prints very nice. However I found the paper very easy to tear, so gentle handling is required.

Though the paper color is a bit warmer I think I would prefer a whiter paper base.

 

[krisbfunk]

any updates on kallitype tests on this paper?

Yeah, it works great!

Yes, my opinion also.
