The rotary printing press was perfected in 1846 and patented in 1847, following an important 1844 patent that laid the groundwork for the design.
Earlier printing presses used reciprocating platforms. However, the rotary printing press replaced these with a fixed platform served by rotating drums, which allowed for much faster printing. The 1844 patent was a key step in the evolution, and further advancements led to the perfected rotary printing press in 1846, ultimately patented in 1847. This invention revolutionized the printing industry.
