Printing

Printing is a process for reproducing text and image, typically with ink on paper using a printing press. It is often carried out as a large-scale industrial process, and is an essential part of publishing and transaction printing.

History

Woodblock printing

Woodblock printing is a technique for printing a text, images or patterns that was used widely throughout East Asia. It originated in China in antiquity as a method of printing on textiles and later on paper. As a method of printing on cloth, the earliest surviving examples from China date to before 220, and from Egypt to the 4th century.^[1]

By 593 A.D., the first printing press was invented in China, and the first printed newspaper was available in Beijing in 700 A.D. It was a woodblock printing. And the Tianemmen scrolls, the earliest known complete woodblock printed book with illustrations was printed in China in 868 A.D. Although movable type was developed in China about 200 years later, it did not supersede the use of block printing.

In Middle East

Woodblock printing on cloth appeared in Egypt by the 4th century, though it is not clear if the Egyptian printing of cloth was learned from China or developed separately. Block printing of text, called tarsh in Arabic was developed in Arabic Egypt during the 9th-10th centuries, mostly for prayers and amulets. It is unclear whether the print blocks were made from metal or wood or other materials.^[2] This technique, however, appears to have had very little influence outside of the Muslim world. Though Europe adopted woodblock printing from the Muslim world, initially for fabric, the technique of metal block printing was also unknown in Europe. Block printing later went out of use in Islamic Central Asia after movable type printing was introduced from China.^[3]

In Europe

Block printing first came to Christian Europe as a method for printing on cloth, where it was common by 1300. Images printed on cloth for religious purposes could be quite large and elaborate, and when paper became relatively easily available, around 1400, the medium transferred very quickly to small woodcut religious images and playing cards printed on paper. These prints were produced in very large numbers from about 1425 onwards.

Around the mid-century, block-books, woodcut books with both text and images, usually carved in the same block, emerged as a cheaper alternative to manuscripts and books printed with movable type. These were all short heavily illustrated works, the bestsellers of the day, repeated in many different block-book versions: the Ars moriendi and the Biblia pauperum were the most common. There is still some controversy among scholars as to whether their introduction preceded or, the majority view, followed the introduction of movable type, with the range of estimated dates being between about 1440–1460.^[4]

Movable type is the system of printing and typography using movable pieces of metal type, made by casting from matrices struck by letterpunches. Movable type allowed for much more flexible processes than hand copying or block printing.

Around 1040, the first known movable type system was created in China by Bi Sheng out of porcelain. China[1]. Sheng used clay type, which broke easily, but Wang Zhen later carved a more durable type from wood by 1298 AD, and developed a complex system of revolving tables and number-association with written Chinese characters that made typesetting and printing more efficient. However, the main method in use there remained woodblock printing.

Around 1450, Johannes Gutenberg introduced what is regarded as an independent invention of movable type in Europe (see printing press), along with innovations in casting the type based on a matrix and hand mould. Gutenberg was the first to create his type pieces from an alloy of lead, tin and antimony – the same components still used today.^[5]

Johannes Gutenberg's work on the printing press began in approximately 1436 when he partnered with Andreas Dritzehen — a man he had previously instructed in gem-cutting—and Andreas Heilmann, owner of a paper mill.^[6] It was not until a 1439 lawsuit against Gutenberg that official record exists; witnesses testimony discussed type, an inventory of metals (including lead) and his type mold.^[6]

Compared to woodblock printing, movable type page setting was quicker and more durable. The metal type pieces were more durable and the lettering was more uniform, leading to typography and fonts. The high quality and relatively low price of the Gutenberg Bible (1455) established the superiority of movable type, and printing presses rapidly spread across Europe, leading up to the Renaissance, and later all around the world. Today, practically all movable type printing ultimately derives from Gutenberg's movable type printing, which is often regarded as the most important invention of the second millennium.^[7]

Rotary printing press

Main article: Rotary printing press

A rotary printing press is a printing press in which the impressions are curved around a cylinder so that the printing can be done on long continuous rolls of paper, cardboard, plastic, or a large number of other substrates. Rotary drum printing was invented by Richard March Hoe, and then significantly improved by William Bullock

Across the world, over 45 trillion pages (2005 figure) are printed annually.^[8] In 2006 there were approximately 30,700 printing companies in the United States, accounting for $112 billion, according to the 2006 U.S. Industry & Market Outlook by Barnes Reports. Print jobs that move through the Internet made up 12.5% of the total U.S. Printing market last year, according to research firm InfoTrend/CAP Ventures.

Offset press

Main article: Offset press

Offset printing is a widely used printing technique where the inked image is transferred (or "offset") from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a film of water, keeping the non-printing areas ink-free.

Currently, most books and newspapers are printed using the technique of offset lithography. Other common techniques include:

• flexography used for packaging, labels, newspapers.
• hot wax dye transfer
• inkjet used typically to print a small number of books or packaging, and also to print a variety of materials from high quality papers simulate offset printing, to floor tiles; Inkjet is also used to apply mailing addresses to direct mail pieces.
• laser printing mainly used in offices and for transactional printing (bills, bank documents). Laser printing is commonly used by direct mail companies to create variable data letters or coupons, for example.
• pad printing popular for its unique ability to print on complex 3-dimensional surfaces.
• relief print, (mainly used for catalogues).
• rotogravure mainly used for magazines and packaging.
• screen printing from T-shirts to floor tiles.

Gravure

Gravure printing is an intaglio printing technique, where the image to be printed is made up of small depressions in the surface of the printing plate. The cells are filled with ink and the excess is scraped off the surface with a doctor blade, then a rubber-covered roller presses paper onto the surface of the plate and into contact with the ink in the cells. The printing plates are usually made from copper and may be produced by digital engraving or laser etching.

Gravure printing is used for long, high-quality print runs such as magazines, mail-order catalogues, packaging, and printing onto fabric and wallpaper. It is also used for printing postage stamps and decorative plastic laminates, such as kitchen worktops.

Impact of the invention of printing

Religious impact

Samuel Hartlib, who was exiled in Britain and enthusiastic about social and cultural reforms, wrote in 1641 that "the art of printing will so spread knowledge that the common people, knowing their own rights and liberties, will not be governed by way of oppression".^[9] For both churchmen and governments, it was concerning that print allowed readers, eventually including those from all classes of society, to study religious texts and politically sensitive issues by themselves, instead of thinking mediated by the religious and political authorities.

It took a long long time for print to penetrate Russia and the Orthodox Christian world, a region (including modern Serbia, Romania and Bulgaria) where reading ability was largely restricted to the clergy. In 1564, a White Russian brought a press to Moscow, and soon after that his workshop was destroyed by a mob.

In the Muslim world, printing, especially in Arabic or Turkish was strongly opposed throughout the early modern period (printing in Hebrew was sometimes permitted). Indeed, the Muslim countries have been regarded as a barrier to the passage of printing from China to the West. According to an imperial ambassador to Istanbul in the middle of the sixteenth century, it was a sin for the Turks to print religious books. In 1515, Sultan Selim I issued a decree under which the practice of printing would be punishable by death. At the end of the century, Sultan Murad III permitted the sale of non-religious printed books in Arabic characters, yet the majority were imported from Italy.

It was thought that the introduction of the printing medium 'would strengthen religion and enhance the power of monarchs.' ^[10] The majority of books were of religious nature with the church and crown regulating the content. The consequences of printing wrong material were extreme. Meyrowitz ^[11] used the example of William Carter who, in 1584, printed a pro-Catholic pamphlet in Protestant-dominated England. The consequence of his action was hanging.

The widespread distribution of the Bible 'had a revolutionary impact, because it decreased the power of the Catholic Church as the prime possessor and interpretor of God's word.' ^[12]

Social impact

Print gave a broader range of readers access to knowledge and enabled later generations to build on the intellectual achievements of earlier ones. Print, according to Acton in his lecture On the Study of History (1895), gave "assurance that the work of the Renaissance would last, that what was written would be accessible to all, that such an occultation of knowledge and ideas as had depressed the Middle Ages would never recur, that not an idea would be lost".^[13]

Print was instrumental in changing the nature of reading within society.

Elizabeth Eisenstein identifies two long term effects of the invention of printing. She claims that print created a sustained and uniform reference for knowledge as well as allowing for comparison between incompatible views. (Eisenstein in Briggs and Burke, 2002: p21)

Asa Briggs and Peter Burke identify five kinds of reading that developed in relation to the introduction of print.

1. Critical Reading- due to the fact that texts finally became accessible to the general population, critical reading emerged because people were given the option to form their own opinions on texts.

2. Dangerous Reading - reading was seen as a dangerous pursuit because it was considered rebellious and unsociable. This was especially in the case of women because reading could stir up dangerous emotions like love. There was also the concern that if women could read, they could read love notes.

3. Creative Reading - Printing allowed people to read texts and interpret them creatively, often in very different ways than the author intended.

4. Extensive Reading - Print allowed for a wide range of texts to become available, thus, previous methods of intensive reading of texts from start to finish, began to change. With texts being readily available, people began reading on particular topics or chapters, allowing for much more extensive reading on a wider range of topics.

5. Private Reading - This is linked to the rise of individualism. Before print, reading was often a group event, where one person would read to a group of people. With print, literacy rose as did availability of texts, thus reading became a solitary pursuit.

"While the invention of printing has been discussed conventionally in terms of its value for spreading ideas, it’s even greater contribution is its furthering of the long-developing shift in the relationship between space and discourse"^[14].
The proliferation of media that Ong is discussing in relation to the introduction of the printing press, to the death of an oral culture and that the new this new culture had more of an emphasis on the visual rather than in an auditory medium. As such the printing press gave birth to a more accessible and widely available source of knowledge in the sense that it broke down the boundaries between the possessors of knowledge and the masses. The narrative or discourse now existed in what would become indirectly through time, the global village.

The invention of printing also changed the occupational structure of European cities. Printer (publisher)Printers emerged as a new group of artisans for whom literacy was essential, although the much more labour-intensive occupation of the scribe naturally declined. Proof-correcting arose as a new occupation, while a rise in the amount of booksellers and librarians naturally followed the explosion in the numbers of books.

Digital printing

Digital printing accounts for approximately 9% of the 45 trillion pages printed (2005 figure) around the world.^[8]

Printing at home or in an office or engineering environment is subdivided into:

• small format (up to ledger size paper sheets), as used in business offices and libraries
• wide format (up to 3' or 914mm wide rolls of paper), as used in drafting and design establishments.

Some of the more common printing technologies are:

• blueprint—and related chemical technologies.
• daisy wheel—where pre-formed characters are applied individually.
• dot-matrix—which produces arbitrary patterns of dots with an array of printing studs.
• inkjet—including bubble-jet—where ink is sprayed onto the paper to create the desired image.
• laser—where toner consisting primarily of polymer with pigment of the desired colours is melted and applied directly to the paper to create the desired image.
• line printing—where pre-formed characters are applied to the paper by lines.
• heat transfer—like early fax machines or modern receipt printers that apply heat to special paper, which turns black to form the printed image.

Vendors typically stress the total cost to operate the equipment, involving complex calculations that include all cost factors involved in the operation as well as the capital equipment costs, amortization, etc. For the most part, toner systems beat inkjet in the long run, whereas inkjets are less expensive in the initial purchase price.

Professional digital printing (using toner) primarily uses an electrical charge to transfer toner or liquid ink to the substrate it is printed on. Digital print quality has steadily improved from early color and black & white copiers to sophisticated colour digital presses like the Xerox iGen3, the Kodak Nexpress, the HP Indigo Digital Press series and the InfoPrint 5000. The iGen3 and Nexpress use toner particles and the Indigo uses liquid ink. The InfoPrint 5000 is a full-color, continuous forms inkjet drop-on-demand printing system. All handle variable data and rival offset in quality. Digital offset presses are called direct imaging presses; although these receive computer files and automatically turn them into print-ready plates, they cannot insert variable data.

Small press and fanzines generally use digital printing or more rarely xerography. Prior to the introduction of cheap photocopying the use of machines such as the spirit duplicator, hectograph, and mimeograph was common.
