Normal oil paint is really not the way to go; litho-etching ink is
harder (and i have the impression less additives).
Even the litho-ink is not stiff enough for me, i add pure pigments to
stiffen; also magnesium-carbonate can be used.
But, like gumprinting, parameters influencing the final result are
Gelatine coating (it took me some time before deciding to stick to 3
layers of 8 to 10 %.)
The potassium carbonate 6 %, coating until the paper is not taken
anymore and it takes a long time to dry.
The exposure, compared to gum it takes about 2 times as much (in my
case with an inkjet-plotter-foil neg.: for gum 600 to 700 seconds,
for oilprint about 1400 seconds)
The ink: if spread very thin on a tile or equivalent, go over it with
a foam roller, try on a sheet of normal paper, result must be a very
Before inking i dry the paper both sides, and wait a bit before
If ink is applied, spray a bit of water over it, and use a clean foam
roller to bring back the contrast.
Hope this helps.
If not, tell me what exactly goes wrong.
