Yes, it is the one in the graphics art section. I have used the developer in producing masks for conventional silver printing. I have not used it in lith printing on photographic paper. I intend to try it for that purpose on Classic Polywarmtone paper as one of my upcoming projects. From what I understand graded Seagull paper works fairly well as a lith paper and I will try a comparison of these two papers. Sorry that I can't give you more help on this at this time. Good luck.
