Printing press

Printing press from 1811, taken in Munich, Germany.

The printing press is a mechanical printing device for making copies of identical text on multiple sheets of paper. It was invented in Germany by the goldsmith and printer Johannes Gutenberg in the 1440s. Printing methods based on Gutenberg's printing press spread rapidly throughout first Europe and then the rest of the world, replacing most block printing and making it the sole genitor of modern movable type printing.

Movable type printing, which allowed individual characters to be arranged to form words, is a separate invention from the printing press. Movable type printing was also invented in Germany by Gutenberg in the 1440s, and in China by Bi Sheng between 1041 to 1048.

Johannes Gutenberg is credited with inventing the first printing press. Although there are several local claims for the invention of the printing press in other parts of Europe, including Laurens Janszoon Coster in the Netherlands and Panfilo Castaldi in Italy, Gutenberg is credited by most scholars with its initial invention. Screw presses for olives and wine were known in Europe since Roman times and Gutenberg was the first to convert the concept for printing uses. Gutenberg's use of mechanical presses, along with other innovations of him, made printing from the start a proto-industrial process with a far greater printing output than with manual work.

Having previously worked as a professional goldsmith, Gutenberg also made skilful use of the knowledge of metals he had learned as a craftsman. He was the first to make his type from an alloy of lead, tin, and antimony, which was critical for producing durable type that produced high-quality printed books, and proved to be more suitable for printing than the clay, wooden or bronze types used in East Asia. To create these lead types, Gutenberg used what some considered his most ingenious invention, a special matrix wherewith the moulding of new movable types at short notice became feasible with an unprecedented precision.

Within a year after his Gutenberg Bible, Gutenberg also published the first coloured printsTemplate:Fact. Gutenberg is also credited with the introduction of an oil-based ink which was more durable than the previously used water-based inks. As printing material he used both vellum and paper, the latter having been introduced in Europe somewhat earlier from China by way of the Arabs, who had a paper mill in operation in Baghdad as early as 794.

Impact of printing

Diffusion of printing in Europe

In medieval Europe, books were first copied mainly in monasteries, or (from the 13th century) in commercial scriptoria, where scribes wrote them out by hand. Books were therefore a scarce resource. While it might take a year or more to hand copy a Bible, with the Gutenberg press it was possible to create several hundred copies a year, with two or three people who could read (and proofread), and a few people to support the effort. As was to be the case until the 19th century, each sheet still had to be fed manually, which limited the reproduction speed; and the type had to be set manually for each new page, which limited the number of different pages created per day. Books produced in this period, between the first work of Johannes Gutenberg and the year 1500, are collectively referred to as incunabula.

The popularity of printed works was not universal. The papal court contemplated making printing presses an industry requiring a license from the Catholic Church (an idea rejected in the end) Template:Fact, but many governmental and religious bodies licensed and censored printing. As early as the 15th century a few nobles refused to have printed books in their libraries, thinking that to do so would sully their valuable handcopied manuscripts. Similar resistance was later encountered in much of the Islamic world, where calligraphic traditions were extremely important, and also in the Far East.

Despite this resistance, Gutenberg's printing press spread rapidly, and within thirty years of its invention in 1453, towns and cities across Europe had functional printing presses. Johann Heynlin, for example, introduced the first press to Paris in 1470. The city of Tübingen saw its first printed work, a commentary by Paul Scriptoris, in 1498. It has been suggested that this rapid expansion shows not only a higher level of industry (fueled by the high-quality European paper mills that had been opening over the previous century) than expected, but also a significantly higher level of literacy than has often been estimated.

The first printing press in a Muslim territory opened in Andalusia in the 1480s. This printing press was run by a family of Jewish merchants who printed texts with the Hebrew script. After the reconquista in the 1490s, the press was moved from Granada to Istanbul (a frequent destination for thousands of Andalusian Jews).

Effects of printing on culture

The discovery and establishment of the printing of books with movable type marks a paradigm shift in the way information was transferred in Europe. The impact of printing is comparable to the development of writing, and the invention of the alphabet, as far as its effects on the society. Print did not achieve a position of total dominance, and handwritten manuscripts continued to be produced. The continuing influences of the printed word and oral communication on each other meant that no one form of communication could dominate.

Printing also was a factor in the establishment of a community of scientists (previously scientists were mostly isolated) who could easily communicate their discoveries, which had previously been communicted by personal letters, helping to bring on the scientific revolution. Also, although early texts were printed in Latin, books were soon produced in common European vernaculars, leading over several centuries to the decline of the Latin language as the medium of scholarly communication.

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 (title), 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 has not been unknown. The process of reading was also changed, gradually changing over several centuries from oral readings to silent, private reading. And obviously, the availability of printed materials led to a continuing rise in the literacy level, revolutionizing education.

It can also be argued that printing changed the way Europeans thought. With the older illuminated manuscripts, the immediate visual emphasis was on the images and the beauty of the page. Early printed works emphasized principally the text and the line of argument. In the sciences, the introduction of the printing press marked a move from the medieval language of metaphors to the adoption of the scientific method.Template:Fact

In general, knowledge came closer to the hands of the people, since printed books could be sold for a fraction of the cost of illuminated manuscripts. There were also more copies of each book available, so that more people could discuss them. Within 50-60 years, the entire library of "classical" knowledge had been printed on the new presses (Eisenstein, 1969; 52). The spread of works also led to the creation of copies by other parties than the original author, leading to the formulation of copyright laws. Furthermore, as the books spread into the hands of the people, Latin was gradually replaced by the national languages. This development was one of the keys to the creation of modern nations.

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 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". It has largely been replaced by computer typesetting programs, which make it possible to get similar results with less human involvement. Some few practitioners continue to print books the way Gutenberg did. For example, there is a yearly convention of traditional book printers in Mainz, Germany.

Printing in the industrial age

The Gutenberg press was much more efficient than manual copying, and as testament to its effectiveness, it was essentially unchanged from the time of its invention until the Industrial Revolution, some three hundred years later. The "old style" press (as it was termed in the nineteenth century) was constructed of wood and could produce 240 impressions per hour of simple work using a well experienced two-man crew.

The invention of the steam powered press, credited to Friedrich Koenig and Andreas Friedrich Bauer in 1812, made it possible to print over a thousand copies of a page per hour.

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 to make 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 press was improved by Applegath and Cooper. The diagram indicates the principle operation of a Cooper and Applegath's Single Machine. The press is built up from a large flat inking table (A) which moves regularly back and forth, the form (B) on the table holds the type. The paper travels clockwise round a large cloth covered cylinder, the impression roller (C), and is pressed against the table. The ductor roller (D) rotates and so draws ink from the attached reservoir. The ink passes from the ductor roller to the vibrating roller (E), this moves, on its arms, in a regular motion between the ductor roller and the table. The ink is spread thinly and evenly by the distributing rollers (F) and then, as the table moves, passes onto the inking rollers (G). The axles of the inking rollers rest in groves, allowing them to rise and fall, they are also position at a slight angle to the table to improve ink distribution. As the table continues to move the form passes alternately under the inking rollers, twice, and then under the impression roller.

Later on in the middle of the 19th century the rotary 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 [iph] 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.

Movable type has been credited as the single most important invention of the millennium.
