Re: oil prints

Hi again Henk, My 10% gelatine coats onto Alu if I give the metal a ''tooth'' with a course scouring powder applied with the rough side of a washing - up pad ( a block of foam with one side of green scouring material). Even this gives a quite fine finish but not as fine as tooth paste.However, it does seem to key the gel coat quite well. I might try carborundum powder to get an even courser grain. At present I am waiting for this gel coating to dry thoroughly before immersing the sheet in the 1% Amm Dich. for 90 secs.
          In the mean time wife and I are going to Tesco stores to buy more cat food and chill out before returning to the excitement of the darkroom. And Henk, just read your great article, again, in Post Factory #9. Very inspiring ! ! ! Thanks.
          Sorry Greg, to hear about your Nikon.
More later. John

  Hi John,
  I did a lot of bromoil on aluminium sheets , starting with the 'beer-coating' and using Liquid Light SE1 .(see the last issue of Judy's PostFactory)
  No problems with the gelatine on the aluminium? What did you use as a first coat?
  Very curious about your results. Succes.
  Cheers,
  Henk

    Henk, It just happens that I had started experimenting with Oil printing onto aluminium sheet when Witho's question came up on the List about his problems with Bergger 240. Not exactly the same, but still dealing with the gelatine hardening reaction when sensitized with Amm. Dich. + UV.
    I will let you know what devastating failures I get after another couple of days........and hopefully a small success.
                            The most recent result was an extremely contrasty positive image from a film negative onto aluminium.It seems the 30 minute exposure with 10% gel + 1% Amm Dich was far too long. Paper negatives appeal to me, too, as they give a longer time scale for exposures.
                Later. John

      Anyway , after weeks of frustrating disasters , using the numbers I found in the literature, I created a lot of acceptable oil-prints up to 50x60 cm with ordinary paper negatives .
      Cheers,
