RE: Lith film and base density

Ryuki,

Do you have any suggestions for this type of additive in a formula?
This would be interesting to me and probably others as well. I always
have benzo on hand for paper developers. Would I just add 10-30 ml to
the liter?

thanks

Darryl

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.
