Re: oilprint second try
I've followed the recipe you give on the alternativephotography.com website with little success. I'm using oil pint as that's all I have available here. How stiff does the paint need to be when applired?. I've seen articles where people talk about using chemicals to stiffen up the ink. Is this necessary with oil paint?

No, I do not 'hop' at all: RSI is not only an IT-problem ....
So, i use exclusively cheap foam brayers.
Clearing is normally very easy by spraying a film of water over the
inked area and go over it with a clean brayer.
Pollmeier uses the hot damp of a small water-boiler, but that was for
bromoil (in the case of bromoil you also can use a water temperature
to 50 degrees Celsius, with oil-printing i never go above 25 Celsius).
And beyond that, I had bad experience with less 3 layers of at least
8% gelatine (and also with exposure times less than 1200 seconds)
