Hello Thomas,(posted 8801 days ago)what kind of Lith Film are you using? I ordered 35mm/30.5 m of Kodak Ortho Lith film, which I have not received yet.
Consider Technical Pan in Rodinal 1:100 or 1:150, developed for 7 min/200C, Dmin around 0.1 and Dmax around 1.5+, develop longer and Dmax will be higher or use 1:50/1:75 to increase contrast. What contrast range were you thinking of? Dmax-Dmin > 2?
Want to try some TP-35 mm, let me know.
Kind regards,
Wolfram
