Adjustment Curves Layer for the DN of the multi-layer gum prints?

Dan Pavel said:

Yes, I know his work and I like it very much.

Tony Gonzalez is another color gum printer I like.

The thin gelatine layer applied on top of the gum layer sticks on it and is not perceived as a separate layer.
If you want to try it I'd advice to first test Palladium on gelatine sized paper till you get it right and then the whole Pd over gum process. If the Pd sensitizer doesn't apply evenly on the gelatine sized paper (there are many kinds of gelatine) just moisten the gelatine layer with a brush, absorb well the excess water with some absorbent paper, let it stay for 3-5 minutes and then apply the Pd sensitiser. It will come out evenly (at least it works for me...).

Sounds interesting, do you find that this gelatin sits as a layer or does it sink in, I have seen carbon transfer that is gelatin sized separate or flake off, probably why I moved away from carbon transfer.

Hi Andrew

This is how my friend John Bentley gets around it , all three matrixces are transferred to a very heavy watercolour paper and is some of the prints a gelatin coating goes over which would solve this.

Sandy King as far as I have seen and I have seen a lot of his prints does not put a coating on the prints as he wants you to see the relief and its really obvious to the naked eye.
I met with Mark Osterman years ago at GEH and this topic was brought into conversation whereas he stated that very old Transfers 100 years plus were in some cases flaking and required conservation efforts, I would imaging a coating of gelatin would be that solution to the problem.
