RE: "New" Paper for Pt/Pd (and other iron processes, too)



Hi Loris,

Yes, it is from a digital negative. The original was a 7X17" in-camera negative.

The image file, at least on my monitor, shows more contrast than the actual print. The file was also greatly reduced in resolution for uploading to the LF site.

This is a DOP palladium print. I am going to do it again with the Ware/Malde and Ziatype POP to compare look. But it will be hard to beat the DOP print. But I am getting great Dmax with the lithium palladium salt so we shall see.

The print looks nice! Is it from a digital negative? If that's not
asking too much, can you please provide a crop of the print (showing
tonality from shadows to the highlights) at 360dpi resolution 100% size
(to let us see the paper texture)? A last question about the print: is
it DOP or POP?

This papers price is very good indeed. I may buy this paper later, just
like as I bought not-100%-cotton (a bad thing to me) Masa paper earlier,
the only drawback is the acidic alum-rosin sizing which makes the
paper's archival qualities questionable. See:
http://www.mikeware.co.uk/mikeware/preparations.html "...Alum-rosin
sized papers (such as Cranes AS 8111) seem to work well, but are
archivally questionable (although Willis's commercial paper was of this
type)...". There's a similar statement in page
http://www.mikeware.co.uk/mikeware/technical.html -> "An Investigation
of Platinum and Palladium Printing" (this is a word document); "...Some
gelatine tub-sized papers were also found to work well with palladium
(but not platinum), and even an alum-rosin sized paper, although the
archival permanence of the latter is open to question(17)..." Reference
(17) is: Green S.B., Fine Print, January (1984). Finally, the same point
was made again in Mike's "The Chrysotype Manual" p.45.

As I said above, the paper's still very very interesting...

Regards,
Loris.

It is very economical, just a little over a dollar a sheet if you
purchase it in 100-sheet quantity.

For comparison, I have used a lot of Stonhenge Rising in the past for
kallitype and Pt./Pd. printing, and the price is about the same.
However, the Weston paper gives much better Dmax and clears better.
In fact, Dmax looks at least as good as with COT 320.

The only negative is that the paper does not have great wet strength
so you have to work with it carefully during wet processing. However,
it is not any worse than the Crane paper that many people use for
Pt./Pd. printing.
