Printing Press

A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium.[1][2] In Germany, around 1440, goldsmith Johannes Gutenberg invented the printing press, which started the Printing Revolution. Modelled on the design of existing screw presses, a single Renaissance printing press could produce up to 3,600 pages per workday,[3] compared to forty by hand-printing and a few by hand-copying.[4] Gutenberg's newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. His two inventions, the hand mould and the printing press, together drastically reduced the cost of printing books and other documents in Europe, particularly for shorter print runs.
