Re: Platine permeability

brittonie,
 

Yes - I’ve had some frustratingly difficult moments with unreliable platine. I have given up on the paper for the most part. Drag, I used to like it once upon a time.

Hi Erik,

The only way to stock Arches Platine is to test a sample from a specific batch first. If it works make a large order of the that same batch.
There is no shortcuts to this approach.
Arches Platine varies  from great to unusable, batch to batch. Period.

Yes indeed,  I found it as good as blotting paper with Gumoil coating & I was using 1-2 drops of wetting agent & was told by the manufacture reps that I should leave out the wetting agent & I must say it did improve but still below the hype that was given to this expensive paper...

Has anyone had an experience with Platine paper where cyanotype chemistry just shoots right through the paper (like it does on an unsized Arches 88)? The paper is definitely labeled Platine and it has gone through a hot water bath which may have removed the sizing but in all the years I have used Platine for cyanoplati or whatnot where I have preshrunk also, it has never shot through with chemistry like this. Almost like the batch wasn’t sized. Paper was bought in May from Artisan in Santa Fe.

Re: Printing digital negatives with Epson SureColor P700?

Thanks to all. Kind of discouraging. Seems like a step backwards for Epson. I never had any problems like that with the R3000.
Does anyone know if the Canon PRO-300 does better with Pictorico?

Thank you, Debbie! I will try that. I am about to print a show in multiple media and am kind of dreading the “fun” of this aspect.

Bonjour Jacques !

So far the cheapest and fastest alternative is to order from B&H in NYC. You can prepay the VAT with them and the package is on your doorstep in 3 to 4 days without having to deal with customs clearance. Despite the cost of shipping + VAT, it is still strangely the cheapest option...

Hi,
I was contacted by a french shop printing digital negatives for their customers.
They used Pictorico transparencies, which they purchased in rolls.
Since about one year now, Innova Art is distributing Pictorico in France, but only in sheets (A3+ maximum). Anybody knows how to get Pictorico in rolls in France?
Thanks & best regards,

Gold toning Cuprotype

Jim Patterson,
 

Hi All,
A while ago I did 2 small experiments with Clerc’s Gold Toner on Cuprotypes. Toning at the CuSCN stage (just after the Thiocyanate/citric acid developer) I got a very fogged neutral gray image.

On a Se/S toned Cuprotype (toned at the CuSCN stage) I got a sharp neutral gray image, with minimal highlight fog.

Perhaps Mike Ware has some thoughts or remedy for the fogging.
Jim


Re: Cyanotype/Cuprotype

Jim Patterson,
 

Hi Niranjan,
The Se/S toner is my favorite.  It is Selenium powder dissolved in Sodium Sulfide solution.  It is listed in Anchel’s Darkroom Cookbook, 3rd Ed, p 296.  I dilute 1:20 for use.  Low odor.

Selenium powder dissolved in sodium sulfite works.  Selenium powder is very toxic by inhalation.  CAUTION.

2 % Sodium Sulfide solution works.
2% Liver of Sulfur (sodium polysulfide) works.
Both of these offgas Hydrogen Sulfide (toxic).

Thiourea sulfide toner does NOT work.
Kodak Rapid Selenium Toner does NOT work.

Some old developers (0.25% solution) bind to the Copper Ferrocyanide and air oxidize to a final color:
Amidol = purple brown
Rodinal = sepia
PPD + Catechol 1:2 = black.

Many of these are toxic.  Fume hood, outdoor ventilation, etc.  Don’t try these in the kitchen or bathroom.
Jim

Hi All, 
I have several Cuprotypes several years old with no blue stains.
If any iron is left in the paper, a Cyanotype blue stain will result.  After developing in the thiocyanate/citric acid solution, wash well in at least 3 trays of citric acid water (1/2 tsp/liter) to remove all residual iron.  Then tone with the potassium Ferricyanide.  You can skip the Ferricyanide toner and use the Selenium/Sulfide toner at this point for a dark brown.

If printing a Cyanotype/Cuprotype combo, print the Cyanotype first to avoid changing the Cuprotype to a Cyanotype.

You can selectively change parts of a Cuprotype to a Cyanotype by using a small brush with Ferric Ammonium Sulfate solution.

Blue staining is probably something to do with not being able to clean out the residual irons, I am guessing but Jim would be the one to ask.
