Was fortunate enough to get ahold of some Soviet era Slavich Bromportrait from 1983. The paper is wonderful for lith printing though exposure times can get up there. Some of these needed exposures of 6 minutes! With shorter development times, the paper has a nice brown tone. Longer developments get the classic yellow lith.
I paired the paper with some negatives shot on Svema MZ3 for consistency. Unfortunately with the paper and the negative being so contrasty, it didn’t always work. Going to try next with some HP5 negatives.

Amazing prints. Well done.
Exposure times of more than 5 minutes at f2.8 are common. I apply long exposures on Arista Brom-Paper and sometimes even on AGFA Portriga as well as Brovira paper.
It is sad that I don’t manage to preserve the purple taint they have before the fix…
