Hi Terry,
My original post was about carbon printing though. Have I been confusing
about my questions?
>> In relation to 'oil pigment printing' I use a very small amount of
chrome
alum in the first of the gelatine coats to provide resistance to the force
of the inking brush and thus keep the gelatine adhered to the paper during
inking up,
>>
I will try "oil pgiment printing" one day, but just to make sure we are
talking about the same thing, do you mean the "gumoil process?" I am
interested in that too, but the examples that I have seen are mainly from the
book "Gumoil Photographic Printing" by Karl Koenig. I don't like the example
shown: too contrasty and coarse. Artistic maybe, but in your experience, is
it possible to make gumoil print that is more realistic?
Also, in your suggestion above, what does the chrome alum do? Is the purpose
of adding the alum mainly to harden the gelatine?
Thanks in advance.
