      This sounds like a carbon-arc platemaker which is of little use in
      exposing photopolymer relief plates. Most likely it is a large floor
      model "flip-top". So if you have a lot of room to spare, you could
      just use the vacuum frame in it and install a exposure box of
      blacklight tubes over it. If I were you, I'd wait for something more
      If it has a mercury-vapor lamp instead of carbon-arc it might be
      OK, but the exposure times are still much longer than with the correct
      UV tubes.
