I saw pictures when I was fifteen? of how newspapers were printed. The mass printing was done by finished, full-scale pages cast in a single curved piece, I think of linotype or maybe monotype (an even harder alloy of lead, tin, antimony).
The finished plates were hemicylinders that mounted on a whacking great roller press.
I don't recall how the plates were cast. But their shape looked like it would fit a scaled-up version of Gaugs' bronze artifact.

I wonder about the crucial step of preparing a smooth, seamless mold for the actual printing plate from discrete elements, like type or etched photo templates. That must have been hard and exacting work.
