RE: polymer gravure idea



Hey Susan,

Perhaps this clarity isn't necessary, but just in case: you'll need a
positive/transparency, not a negative for an intaglio print. Relief plates,
however, require a negative.

Some of my own early observations using solar plates:

1. You do NOT need OHP transparency film to get a good plate. Office Depot
quality ink jet transparencies work extremely well and they dry in about 30
seconds. I think this statement is even more true for
print-making-photographers vs. photographer-printmakers. So my suggestion is
to pull out of piece of cheap transparency film, and draw on it, paint on
it, or print a digital image onto it; and then expose it onto a plate.

2. As Chris pointed out, the aquatint screen is essential. Every plate I
made without first exposing the plate with the screen has found its way to
the trash.

3. Exposure times are very forgiving. Some images look nearly identical
whether I exposed them for 1 min or 6 min using the same uv source. In
general, however, the plates seem to do best with the shortest exposure
possible--I'm not sure why, but this is my own limited experience.

4. Vacuum and quality contact print frames may not actually be advantageous.
My fellow photographers are probably gasping right now, but I simply cant
tell the difference between a plate made using a very good quality contact
print frame and the cheap print frame I was given when I was taught this
technique which consists of a piece of glass on top of fabric batting and
then taped to a piece of cheap board. Perhaps it matters more with certain
images.

5. Haven't tried it personally, but my printmaking friends tell me the
plates can't be worked after exposure.

I'm writing this after working my third 12-hour night shift in a row so I
might re-write portions after I've gotten some sleep.

Hi,

I'm impatiently waiting for my OHP and aquatint screen to arrive so I
can start testing exposures and digineg output, etc.  (and I just
realized I'm supposed to wait 24 hours for the neg to dry
arrrrgggghhhhh ).

So while I'm waiting, I came up with a question for you who work with
this polymer:  Has anyone tried working on the plate after it's
exposed and hardened?  Is the material "carvable", or soft enough
(meaning softer than the steel tool i'd be using), to inscribe or
otherwise mess with in the way an intagio copper or zinc plate can be
done?
