      Hi Shelly,
      You must have missed the exchange of emails about NuArc earlier this week.
      These frames were designed for exposing offset printing plates but can be
      adapted for exposing pp.


      With a NuArc vacuum frame, the normal exposure lights probably are not
      appropriate for UV light. I use a bank of UV fluorescent bulbs, in a box that I
      place on top of the glass.

      The main problem with a vacuum frame is that, in fact, the vacuum bends the
      glass. Even a slight distortion of the glass allows an uncertain contact
      between the negative and the plate material. The result is an irregular plate
      with some edges swollen wherever more light could get around the negative. Good
      contact between the negative and the plate material is critical.

      A simple solution is to add pieces of mat-board around the plate material in
      the frame to support the glass. No more bending glass, no problem with
      irregular exposure. Works well for me.

      (Another solution would be to replace the glass top with kreene, a flexible
      vinyl, which should provide a consistent contact between the negative and the
      plate. Kreene is available from Boxcar Press).

        Hi all, this is my first post to this list I think, I have had a
        question about the colour of Artwork before exposing it to a negative, I
        have always used black and thought this was the only colour you can use,
        but I have a client that has artwork in Green, will this work as far as
        exposing a negative or will only black work.

        Plus does anyone know of a good supplier of plates, preferably
        in Australia, or the USA will do if none in Australia, I was in line to
        buy them off Edward Keller in Victoria but I'm not sure if they sell
        them any longer.

        Regards,

        Milton Watkins.

            who, by the way, had that day gotten his pink slip, mentioned
            to me that Kodak no longer made a true panchromatic film.
            Does anybody still make a true panchromatic film?
