printing press

A printing press is a mechanical device for applying pressure to an inked surface resting upon a medium (such as paper or cloth), thereby transferring an image. The mechanical systems involved were first assembled in Germany by the goldsmith Johannes Gutenberg around 1440, based on existing screw-presses used to press cloth, grapes etc., and possibly to print woodcuts, which were printed in Europe before Gutenberg. Although both woodblock printing and movable type printing press technologies were already developed first in China, and Korea in East Asia several hundred years earlier, Gutenberg was the first in Western Europe to develop a printing press.

The use of a press was a key technological difference provided European book publishers increased profits over their ancient Chinese counterparts—the screw-based presses used in wine and olive oil production. Attaining mechanical sophistication in approximately the year 1000, devices for applying pressure on a flat-plane were common in Europe.

The printing press was also a factor in the establishment of a community of scientists who could easily communicate their discoveries through the establishment of widely disseminated scholarly journals, helping to bring on the scientific revolution. Because of the printing press, authorship became more meaningful and profitable. It was suddenly important who had said or written what, and what the precise formulation and time of composition was. This allowed the exact citing of references, producing the rule, "One Author, one work , one piece of information" (Giesecke, 1989; 325). Before, the author was less important, since a copy of

Aristotle made in Paris would not be exactly identical to one made in Bologna. For many works prior to the printing press, the name of the author was entirely lost.
Because the printing process ensured that the same information fell on the same pages, page numbering, tables of contents, and indices became common, though they previously had not been unknown. The process of reading was also changed, gradually changing over several centuries from oral readings to silent, private reading. The wider availability of printed materials also led to a drastic rise in the adult literacy rate throughout Europe.

Within fifty or sixty years of the invention of the printing press, the entire classical canon had been reprinted and widely promulgated throughout Europe .Now that more people had access to knowledge both new and old, more people could discuss these works. Furthermore, now that book production was a more commercial enterprise, the first copyright laws were passed to protect what we now would call intellectual property rights. A second outgrowth of this popularization of knowledge was the decline of Latin as the language of most published works, to be replaced by the vernacular language of each area, increasing the variety of published works. Paradoxically, the printed word also helped to unify and standardize the spelling and syntax of these vernaculars, in effect 'decreasing' their variability. This rise in importance of national languages as opposed to pan-European Latin is cited as one of the causes of the rise of nationalism in Europe.

The art of book printing
For years, book printing was considered a true art form. Typesetting, or the placement of the characters on the page, including the use of ligatures, was passed down from master to apprentice. In Germany, the art of typesetting was termed the "black art," in allusion to the ink-covered printers. The Black Art Press & Print in Baltimore, MD adopted their name for this reason. It has largely been replaced by computer typesetting programs, which make it easy to get similar results more quickly and with less physical labor. Some practitioners continue to print books the way Gutenberg did. For example, there is a yearly convention of traditional book printers in Mainz, Germany.
Some theorists, such as McLuhan, Eisenstein, Kittler, and Giesecke, see an "alphabetic monopoly" as having developed from printing, removing the role of the image from society. Other authors stress that printed works themselves are a visual medium. Certainly, modern developments in printing have revitalized the role of illustrations.

The Industrial Revolution
The Gutenberg press was much more efficient than manual copying and still was largely unchanged in the eras of John Baskerville and Giambattista Bodoni—over 300 years later. By 1800, Lord Stanhope had constructed a press completely from cast iron, reducing the force required by 90% while doubling the size of the printed area. While Stanhope's "mechanical theory" had improved the efficiency of the press, it still was only capable of 250 sheets per hour.German printer Friedrich Koenig would be the first to design a non-manpowered machine—using steam. Having moved to London in 1804, Koenig soon met Thomas Bensley and secured financial support for his project in 1807.Patented in 1810, Koenig had designed a steam press "much like a hand press connected to a steam engine."The first production trial of this model occurred in April 1811. He produced his machine with assistance from German engineer Andreas Friedrich Bauer.

Koenig and Bauer sold two of their first models to The Times in London in 1814, capable of 1,100 impressions per hour. The first edition so printed was on November 28, 1814. They went on to perfect the early model so that it could print on both sides of a sheet at once. This began the long process of making newspapers available to a mass audience (which in turn helped spread literacy), and from the 1820s changed the nature of book production, forcing a greater standardization in titles and other metadata. Their company Koenig & Bauer AG is still one of the world's largest manufacturers of printing presses today.

Later on in the middle of the 19th century the rotary printing press (invented in 1833 in the United States by Richard M. Hoe) allowed millions of copies of a page in a single day. Mass production of printed works flourished after the transition to rolled paper, as continuous feed allowed the presses to run at a much faster pace.
Also, in the middle of the 19th century, there was a separate development of jobbing presses, small presses capable of printing small-format pieces such as billheads, letterheads, business cards, and envelopes. Jobbing presses were capable of quick set-up (average makeready time for a small job was under 15 minutes) and quick production (even on treadle-powered jobbing presses it was considered normal to get 1,000 impressions per hour with one pressman, with speeds of 1,500 iph often attained on simple envelope work). Job printing emerged as a reasonably cost-effective duplicating solution for commerce at this time.

A late 1930's Platen printing press model
By the late 1930s or early 1940s, printing presses had increased substantially in efficiency: a model by Platen Printing Press was capable of performing 2,500 to 3,000 impressions per hour.
Later inventions in this field include the following:
