rotary press

The rotary press accelerated book publishing, and with inexpensive wood pulp paper, ultimately lowered the price of a hardcover volume.

The giant rotary press was quite capable of churning out masses of printed material.

Newspapers became tools of mass communication in the 1830s with the invention of the rotary press and the application of steam power to printing.

Back then, it was the telephone, high-speed rotary presses, stereotyping, typesetting machines, color presses, rotogravure and the electric-telegraphic typewriter.

The progress is due to the invention of the rotary press and other improvements in printing machinery.
