Litho film is designed for opaque black and clear transparent result.
I only tried what I had on hand: generic print dev, D-76 and Rodinal clone. Normal dilutions resulted black and clean with no tones. So I tried increasingly diluted Rodinal until I got thin result with at least some tones on it.
If you want cheap AND tones, I'd suggest trying paper negatives.
(Multigrade RC paper negative, 18x24cm(?), a piece of yellow gel on pinhole to make it soft grade, about 7min exposure if I remember right.
Fow. more than 110 degrees diagonal I guess...The scan is from 2014)
