George,
Looks like a problem I've had, but with finer "pitting" that vaguely
resembles very coarse reticulation. It occurred for me on Arches Aquarelle
hot-pressed paper, and I believe it is caused by uneven absorption of the
sensitiser. The paper you're using may be partly to blame, but maybe you're
also making it too wet. I got rid of it by slapping on the first coat
quickly (w/foam brush), then going over it with a dry brush, and then a hair
dryer. It's not necessary to get it bone dry at this stage, just don't
allow the paper to stay too wet for too long. After the hair dryer, I give
a second coat in the same way, and print when thoroughly dry.
At the moment I'm using Arches Platine and have had no problems with it.
(But it prints a lot more contrasty than other papers.) In my experience,
papers can vary a bit from batch to batch, so if the same paper has been OK
for you before, maybe this batch isn't sized quite as well.
Unless someone has another explanation...
Liam

Subject: Van Dyke Problem
I've been doing Van Dyke for quite some time (well, on and off), and have
come
across a real problem. I am getting some sort of pitting in my images, and
I
can't seem to track down the source of the problem. An example of a test
strip
showing this can be found at
http://mywebpages.comcast.net/hmpi/Temp/Pitting.jpg.
I am using the standard chemical (the first formula found in Judy's
publication, volume 1), so there's nothing weird there. I apply with a foan
brush. I am developing with water for about 3-4 minutes, fixing with a 5%
sodium thiosulfate solution for about 3 minutes, then washing (I've tried
using
and not using PermaWash, without any difference). I am using Arches
Aquarelle,
which in the past has worked just fine.
As far as I know, there has been no change in the water.
Does this problem look familiar to anyone? I haven't had this problem in
the
past and it first started happening about two months ago. I put everything
down, as I didn't have time to do any alt process, but returning I am seeing
the same problem.
Any ideas would be greatly appreciated.
Cheers -
george
