The old process was positive art-work (usually reflective, but transmissive would be possible using a special re-pro camera set up) to neg lith film to plate. But regardless of art-work source the main limitations in 4 colour print are the screen size and grid orientation, the precision of the press and the gamut of the inks. None of these elements were near as good as they are now back in the 60's. Unfortunately I can't find any support for my assertions on the web, discussion of pre-computer plate making is very thin on the ground. All my knowledge simply stems from spending time in and around the print/pre-press industry during their transition to computer based pre-production right through to direct digital to plate.
