Re: oilprint second try

[Kees Brandenburg <ctb@zeelandnet.nl>]

Dag Henk,

For bromoil I'm also using litho inks (charbonel, G&C) and sometimes  
the non-coloured G&C extender with added powder pigments. 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 carefull 'hopper'.

Have you been to eurobrom in Brussels this weekend?

regards,

kees
