I asked this question to know if an oilprint in your opinion, needs
the same stiff inks as a bromoil. So your answer is: yes it does.
As a listlurker from 'the old days' I had allready seen and printed
Klaus Pollmeier's receipe - and wondered if the, maybe more
fragile, gelatin of an oilprint indeed needed some little pre-
hardening. I noticed that the non-hardened highlight parts in my
gelatin layer sometimes don't support heavy inking resulting is a
stained paper base in the highlights. So you probably are a
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)
Have you been to eurobrom in Brussels this weekend?

what inks do you use?
To stiff the ink i add pure pigment, by-effect is the possibility
of changing color .
do you use plain gelatin whithout any hardener when coating your
There is a recipe from the 'old days' of the list from Klaus
-prepare 140 ml of a 15% gelatin solution;
-add 14 ml of a 15% potato starch solution;
- while stirring, slowly add 14 ml of a hardener , made by mixing
6 ml of a 6% sol. of acetic acid and 8 ml of a 1% sol. of chrom.
From the text ' .... the hardener really helps to avoid blistering
and having the gel. detach from the paper base....'
I tried that one, but found no difference to my method:
just 3 times a gelatine layer of about 8% gelatine, with a 6 %
