Re: oil prints

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,

      I just tried the same negative with the same exposure time for a carbon print. The catron was very overexposed. So for the brom 240 this must have been enough.

      Cheers,

      It is already time for tea.

      Hi Witho, What is the % strength of your sensitizer and how is it applied to the fixed out Bergger 240? Brushing or by immersion? Exposure times might have something to do with the question, too.
               Woof, woof. Have a good day. John.
