Rotary printing press

Substrates can be sheet feed or unwound on a continuous roll through the press to be printed and further modified if required (e.g. die cut, overprint varnished, embossed).

[1][2] Rotary drum printing was invented by Josiah Warren in 1832,[3] whose design was later imitated by Richard March Hoe in 1843.

[4] An 1844 patent replaced the reciprocating platforms used in earlier designs with a fixed platform served by rotating drums, and through a series of advances a complete rotary printing press was perfected in 1846,[5] and patented in 1847.

[6] Some sources describe the Parisian Hippolyte Auguste Marinoni as the inventor of the Rotary printing press, but this was the subject of a patent dispute that was decided in Hoe's favor.

A.S. Abell of the Baltimore Sun was the first American user of the rotary press.
