I presume the dollar a print development cost is for a

of home mixed stuff? It is possible that it could be
significantly cheaper. If, as Tim Rudman states, acetone CAN
be used in a lith developer it should help. Acetone is
available at any paint or hardware store and is very cheap.
Probably pure enough for the purpose. The developer would
probably have to be mixed as needed but there may be some
way of making up a stock solution minus the acetone which
would be more convenient.
I no longer remember what Kodak has/had in their
commercial lith developer but I do remember that it did not
seem to be D-85. There may be yet another alternative to
formaldehyde or acetone.
MSDS for Kodalith Super-RT developer. Pretty much the same as the
regular stuff, I believe.
