Subject: Re: solarplate problems
Hi Hellena,
Toyobo is different than
Solarplate. Toyobo's photosensitive layer is made of Nylon....Solarplate
is from some other kind of plastic. Not sure what.
Toyobo also
has a mylar layer one must peel off before exposing and processing, where
solarplate does not. That's not the problem, is it?
Otherwise,
I'm sure they have different exposure times. What they will be will
depend on your particular approach. I'd recommend you start with a broad
step tests and start narrowing down. Dan Welden's book is a great
resource.
Good luck!

I purchased my first batch of solarplate last
year at Intaglio Printmakers supplies in London. It had no commercial
name but just solarplate written in pencil. I recently bought another batch
described as Toyobo solarplate and with no instructions provided. I
have been following the Dan Weldon and Pauline Muir book. The
Toyoba does not seem to be working the same way as the earlier stuff- even
to getting an exposure on a Stouffer step wedge. It seems to require more
exposure. Basically, is it me or is this material slightly different?
( The UV unit is okay because I was able to use the earlier material.)
All suggestions and help gratefully received.
