The press is a device for printing text and graphics on paper, exerting pressure on the sheet of paper placed on a plate, set of embossed characters or woodcut, pre-inked so that the ink is deposited on paper. Repeated operation provides a large number of identical copies. This is the focus of printing press kits, together with the use of mobile lead characters and specific greasy ink, which is the major invention of Johannes Gutenberg.
It is certain that the Chinese and Koreans have used characters in earlier times, but they have not used machines that characterize the work of Gutenberg. The press was the basis of print jobs for several centuries until it was supplanted by the offset press. The first press used by Gutenberg drew heavily from various presses used by other professions: a transverse on two uprights, a central wood screw actuated by a lever and a plate carrying pressure.
Until 1450 and even beyond, the books were disseminated in manuscript copies by writers many of whom were monks and friars dedicated exclusively to prayer and custom replica copies of the clergy, kings and nobles. Despite popular belief, not all copyist monks were literate. In the Middle Ages, engraving was used in Europe to publish political advertisements, labels, and few work sheets or pamphlets.
For medium format, the pressure is sufficient. Originally, the operator merely pressed manually, then the presses automatically put more pressure. On this basic principle, many machines with different variants were created. These machines use as letterpress, are still available even if they are no longer used.
New systems and structures never completely erased the earlier developments, but they simply overlapped. Thus, new techniques of information storage and retrieval have caused the print media to regroup and find new placements, often more specialized.
Despite their success and efficiency, cylinder presses have a default typographic planar lead especially in large formats which represents a considerable mass. It is animated by the rocking movement that resulted in vibration and energy loss. Heavy machinery must be based on solid masonry. The rotary press is a cylinder with the difference that the form is no longer flat, but adapted to a rotating cylinder.
From a traditional composition, a blank is a kind of mold, it is cast from which lead is handled, so it has a composition of an entire page in a single block, which can be bent to fit a cylinder. The reciprocating motion of heavy form is replaced by a rotary motion (hence the name). Continuous, smooth and fast print speed is performed on a paper roll (cut in output release). All newspaper printers adopted the rotary.
As a printing plate, Gutenberg molded an old wine press that held the bracket with movable type fitted with a hole for the capital letters and drawings. The Rotary Hoe still uses paper sheets, and William Bullock imagined replacing sheets per paper rolls, thereby further increasing the print speed. The Rotary Hoe was used in 1871 by The New York Tribune. It prints both sides of paper in a single pass and produces 18,000 newspapers per hour.
