what paper for Ware's New Cyanotype?

Try sizing with gelatin if you want smoother tones. It may also help with the speckling effect, as the solution does not come into contact with the paper.

 

I like Crane's Weston Diploma Parchment - smooth texture yielding good detail. And tea-toning gives good results. Also, btw, its inexpensive too.

 

New Cyanotype is very sensitive to paper, and gelatine sizing will not help.
I second the Weston doploma... I tried once the first batch when the paper was newly announced, and it worked beautifully. (New Cyanotype is my way of testing paper: if this process works, others will also.)
You may bring a range of other papers into service, however, by pre-coating them with citric acid (try a 40% solution).

 

I just did it with really old sensitizer with ClearPrint Vellum. Worked great and a very different look

 

I use Bienfang 360. But I have whole flat files full of drafting vellum, I'll have to give that a try.

 

Okay, I won't argue against that. I've got only limited experiences with Whatman HP and Buxton paper.

 

where can you still find the weston diploma paper? I've been looking and can't find it anywhere...

 

I have not tried Arches Aquarelle for a long time. I have never been very successful with this paper, but that was then (probably at least 6-7 years back). The issue of density is serious. For me at least, tonality should be first-rate, just like a platinum print, only in blue, or is it not worth it.

Try tween 20 instead of fotoflo, or leave it all out. I actually found Saunders Waterford HP a good paper, but *only after a citric pre-coat*. I sometimes neutralize paper before in a 1% hydrochl. acid bath (which has to be washed out afterwards!), this often makes the paper more receptive, but I still need the citric pre-coat (though less of it).
How do you apply the first acid bath? Try not to pour it over the picture, but pout the acid first into a tray considerably larger than the paper, tilt the tray to move the acid to one side, carefully place the paper in that part of the tray not covered by the acid - make it stick somewhat to the wet ground - then swiftly move the tray into an even position, if necessary, lifting it in one move there were the acid was when it was tilted, so that the acid floods in an even move over the paper. Rock only very gently, and wash the paper also very gently (face down, gentle water flow only at the back), possibly add a little bit vinegar into the water. If you still observe flakes of blue coming off, you need to do something about your paper base (see above).
Once the paper is dry, the blues will be stable (provided you don't sprinkle some alkali on them).

 

Are you guys making up your Cyanotype II solution or buying it premade and if so where from? I have been using Fabriano Rospina with very little problems over the last 5 years, very cheap 25 sheets for £16 although i have bought my sensitiser pre-made. I am now trying to make my own and having quite a few problems with the Fabriano, all sorts of speckles, uneven coating etc... Have just bought 1/2 Kg of Ammonium Iron (III) Oxalate and am will be making some more batches of sensitiser over the next few days to try and solve the problems.

 

Are you making the traditional sensitiser?

Tom.

 

No Cyanotype II.

 

Sorry to answer so late, I have been without internet access for some time.
I have always made my own sensitizer (trad. and new).

 

Last week I got good result with Schut Terschelling hot pressed paper and New Cyanotype.
Today I got speckles, terrible !
It makes me crazy. Is this paper is not consistent? I did all the same as last week. Each mL sensitizer 1 drop wetting agent + 1 drop citric acid. Coat with glass rod, dry 15 min in an box with soft warm wind blowing. 100 seconds UV light an develop in 1% acetic acid
I have no idea what's to do. Did Pre-soak the paper 10 minutes in 5% hydrochloric acid (dry , flatten) no great solver. Should I try pre-soak with 40 m/v % citric acid ?
Any tips. Please look at attachment for kind of speckles
I use as wetting agent Agfa Agepon. Is this OK , or should i use Tween ? (find reseller for that stuff) I've also a bottle Rollei RWA here, but not tried yet.

 

Did small test today. Measure pH of Agfa Agepon wetting agent. Wow it's pH 9. That's not fine.
Also check Rollei RWA wetting agent, that's better pH is 6 !
So I store old Agfa stuff for other use and use Rollei for cyanotype.
Small test with 3 small pieces of paper: improvement less pronounced speckles (but not complete gone) with Rollei RWA and fast circa three times movement of the chemicals with a rod on a paper.
Longer move the rod over the paper is no good seems.
