I'm about to start making lith developer from scratch. This will be for lith printing. I can't justify spending 50$ for 500ml of LD20 or Moersch chemistry; not when the raw chemicals are relatively inexpensive and used so sparingly.

I'll be making formula with paraformaldehyde. I've found the paraformaldehyde free versions to be lacking on more than a few levels.

I'd like to know people's thoughts on dilution for printing. Should I aim to have a certain amount of hydroquinone per litre of working solution? Should I aim for a specific alkalinity?

I'll probably start with D-85, and try others like Ansco-79B.

Any thoughts on the subject would be much appreciated!
