Color photocopies could be the easy solution. As for film I'd use a 25 ISO
Kodak (called Royal Gold in Europe) for color or a TMX or even a TP in b&w.

I'd use the 50 or the 85 with maybe the rings (12mm should be enough). Set
to f/8 as preference. As for the camera, working with the flashes I'd use
the PC or the 2n, for TTL OTF flash control.
Working on continuous light, I'd try to expose on the white of the photos
and then open 2 1/2 stops. A lot of bracketing is recommended.
The b&w process needs to be *pushed* for getting a higher contrast. Kodak
recommends HC 110, but with TP every developer should do the trick.
For getting parallelism on repro stand, someone suggested on this list to
put a mirror on the plate and then to find the centre of the lens image.
