I have an old box of Kodalith sheets someone gave me, and I have been thinking of trying to make some line duplications, not continuous tone prints. Frankly, I don't know if the film is any good, and I don't want to spend a bunch of money on lith chemicals to find out it's not.
If I contact expose this under my enlarger with the line drawing I want, can I simply develop the daylights out of it in a high concentration of regular developer, something like DD-X? Or will that give me fogging in the parts that should be clear? Is the two part lith developer required to get the totally black/white separation it's designed for?
