there're a lot of specialized lith developer; lith process start when a hydroquinone developer is used. Anyone has experience diluting Ilford Multigrade developer to have a lith print? normally it is diluted at 1+9 but maybe with high dilution you can have lith print. Furthermore i red that old and exausted developer is better to have lith print.
ps. the same question for tetenal Eukobrom developer...
