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. Hellena
