Rotary printing press

The rotary printing press solved the bottleneck of flatbed impression speed by rotating type cylinders against a fixed platform. It worked because rotation enabled stable, repeatable contact at scale. Its 1846 form was deployable; its 1870 web perfecting variant automated cutting and folding at 18,000 papers/hour. It did not eliminate manual feeding until the 1870 version. It changed publishing by making daily mass print economically viable. It matters for anyone studying how mechanical standardisation enables information scale.
