Lith films are made for different chemical properties than usual
continuous tone negative material, and they can exhibit elevated fog
when processed in developers typical for continuous tone processing.
This can be most effectively taken care of by addition of small amount
of benzotriazoles or other common antifoggants such as
1-phenyl-5-mercaptotetrazole. It is not necessary to change developers
just for this purpose.
