FWIW, to the curious, RA2000 is a developer for
machine processing graphic arts film used in the preparation
of half-tone printing plates and color proofs. If anyone
is still making plates from film ...

Kodalith and other lithography developers used in general
photography are only for tray use and won't work well
in automated machines.

I guess that is a long-winded way of saying I haven't a
clue.

The answer to that is yes, a lot of (small) printers still are, at least
those who haven't switched to CTP (computer-to-plate), which is still
expen$ive. However, almost of all of these same printers get their film
from imagesetters (digital input--> film output), not directly from
cameras, so they wouldn't be using RA2000.

The next-to-last printer I worked for did just this, burning plates the
old-fashioned way from film produced by an old Linotronic filmsetter.

Depending on your purpose a standard paper developer will work or try
Kodak's D-8, I've had some luck with both, using the Konica RA material
(I used to get the roll ends for free when I worked for the paper).
