Letterpress printing
Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink from the type, which creates an impression on the paper.
In practice, letterpress also includes wood engraving; photo-etched zinc plates ; linoleum blocks, which can be used alongside metal type; wood type in a single operation; stereotypes; and electrotypes of type and blocks. With certain letterpress units, it is also possible to join movable type with slugs cast using hot metal typesetting. In theory, anything that is "type high" can be printed using letterpress.
Letterpress printing was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century through the 19th century, and remained in wide use for books and other uses until the second half of the 20th century. The development of offset printing in the early 20th century gradually supplanted its role in printing books and newspapers. More recently, letterpress printing has seen a revival in an artisanal form.
History
Movable type printing was first invented in China using ceramic type in AD 1040 during the Northern Song dynasty by the inventor Bi Sheng.Johannes Gutenberg is credited with the development in the West, in about 1440, of modern movable type printing from individually cast, reusable letters set together in a "forme". Gutenberg also invented a wooden printing press, based on the extant wine press, where the type surface was inked with leather-covered ink balls and paper laid carefully on top by hand, then slid under a padded surface and pressure applied from above by a large threaded screw. It was Gutenberg's "screw press" or hand press that was used to print 180 copies of the Bible. At 1,282 pages, it took him and his staff of 20 almost 3 years to complete. 48 Gutenberg Bibles remain intact today. This form of presswork gradually replaced the hand-copied manuscripts of scribes and illuminators as the most prevalent form of printing. Printers' workshops, previously unknown in Europe before the mid-15th century, were found in every important metropolis by 1500. Later metal presses used a knuckle and lever arrangement instead of the screw, but the principle was the same. Ink rollers made of composition made inking faster and paved the way for further automation.
Industrialization
With the advent of the Industrial Revolution and industrial mechanisation, inking was carried out by rollers that passed over the face of the type, then moved out of the way onto an ink plate to pick up a fresh film of ink for the next sheet. Meanwhile, a sheet of paper slid against a hinged platen, which then rapidly pressed onto the type and swung back again as the sheet was removed and the next sheet inserted. As the fresh sheet of paper replaced the printed paper, the now freshly inked rollers ran over the type again. Fully automated 20th-century presses, such as the Kluge and "Original" Heidelberg Platen, incorporated pneumatic sheet feed and delivery.Rotary presses were used for high-speed work. In the oscillating press, the forme slid under a drum around which each sheet of paper was wrapped for the impression, sliding back under the inking rollers while the paper was removed and a new sheet inserted. In a newspaper press, a papier-mâché mixture called a flong was used to make a mould of the entire form of type, then dried and bent, and a curved metal stereotype plate cast against it. The plates were clipped to a rotating drum and could print against a continuous reel of paper at the enormously high speeds required for overnight newspaper production.
This invention helped aid the high demand for knowledge during this time period.
North American history
Canada
Letterpress printing was introduced in Canada in 1752 in Halifax, Nova Scotia, by John Bushell in the newspaper format. This paper was named the Halifax Gazette and became Canada's first newspaper. Bushell apprenticed under Bartholomew Green in Boston. Green moved to Halifax in 1751 in hopes of starting a newspaper, as there had never been one in the area. Two weeks and a day after the press he was going to use for this new project arrived in Halifax, Green died. Upon receiving word about what happened, Bushell moved to Halifax and continued what Green had started. The Halifax Gazette was first published on March 23, 1752, making Bushell the first letterpress printer in any of the areas that later became Canada. There is only one known surviving copy of the first number, which was found in the Massachusetts Historical Society.United States
One of the first forms of letterpress printing in the United States was Publick Occurrences Both Forreign and Domestick started by Benjamin Harris. This was the first form of a newspaper with multiple pages in the Americas. The first publication of Publick Occurrences Both Forreign and Domestick was September 25, 1690.Revival and rise of craft letterpress
Letterpress started to become largely out-of-date in the 1970s because of the rise of computers and new self-publishing print and publish methods. Many printing establishments went out of business from the 1980s to 1990s and sold their equipment after computers replaced letterpress's abilities more efficiently. These commercial print shops discarded presses, making them affordable and available to artisans throughout the country. Popular presses include, in particular, Vandercook cylinder proof presses and Chandler & Price platen presses. In the UK there is particular affection for the Arab press, built by Josiah Wade in Halifax.Letterpress recently has had a rebirth in popularity because of the "allure of hand-set type" and the differences today between traditional letterpress and computerized printed text. Letterpress is unique and different from standard printing formats that we are currently used to. Letterpress commonly features a relief impression of the type, although this was considered bad printing in traditional letterpress. Letterpress's goal before the recent revival of letterpress was to not show any impression. The type touched the paper slightly to leave a transfer of ink, but did not leave an impression. This is often referred to as "the kiss". An example of this former technique would be newspapers. Some letterpress practitioners today have the distinct goal of showing the impression of type, to distinctly note that it is letterpress, but many printers choose to maintain the integrity of the traditional methods. Printing with too much impression is destructive to both the machines and to the type. Since its revival letterpress has largely been used for fine art and stationery as its traditional use for newspaper printing is no longer relevant for use.
Letterpress is considered a craft as it involves using a skill and is done by hand. Fine letterpress work is crisper than offset litho because of its impression into the paper, giving greater visual definition to the type and artwork, although it is not what letterpress traditionally was meant for. Today, many of these small letterpress shops survive by printing fine editions of books or by printing upscale invitations, stationery, and greeting cards. These methods often use presses that require the press operator to feed paper one sheet at a time by hand. Today, the juxtaposition of this technique and offbeat humor for greeting cards has been proven by letterpress shops to be marketable to independent boutiques and gift shops. Some of these printmakers are just as likely to use new printing methods as old, for instance by printing using photopolymer plates on restored vintage presses.
Martha Stewart's influence
Letterpress publishing has recently undergone a revival in the US, Canada, and the UK, under the general banner of the "Small Press Movement". Renewed interest in letterpress was fueled by Martha Stewart Weddings magazine, which began using pictures of letterpress invitations in the 1990s. In 2004 they state "Great care is taken in choosing the perfect wedding stationery – couples ponder details from the level of formality to the flourishes of the typeface. The method of printing should be no less important, as it can enliven the design exquisitely. That is certainly the case with letterpress." In regards to having printed letterpress invitations, the beauty and texture became appealing to couples who began wanting letterpress invitations instead of engraved, thermographed, or offset-printed invitations.Economical materials
Affordable copper, magnesium and photopolymer platemakers and milled aluminum bases have allowed letterpress printers to produce type and images derived from digital artwork, fonts and scans. Economical plates have encouraged the rise of "digital letterpress" in the 21st century, allowing a small number of firms to flourish commercially and enabling a larger number of boutique and hobby printers to avoid the limitations and complications of acquiring and composing metal type. At the same time there has been a renaissance in small-scale type foundries to produce new metal type on Monotype equipment, Thompson casters and the original American Type Founders machines.Process
The process of letterpress printing consists of several stages: composition, imposition and lock-up, and printing. In a small shop, all would occur in a single room, whereas in larger printing plants, such as with urban newspapers and magazines, each might form a distinct department with its own room, or even floor.Composition
Composition, or typesetting, is the stage where pieces of movable type are assembled to form the desired text. The person charged with composition is called a "compositor" or "typesetter", setting letter by letter and line by line.Traditionally, as in manual composition, it involves selecting the individual type letters from a type case, placing them in a composing stick, which holds several lines, then transferring those to a larger type galley. By this method the compositor gradually builds out the text of an individual page letter by letter. In mechanical typesetting, it may involve using a keyboard to select the type, or even cast the desired type on the spot, as in hot metal typesetting, which are then added to a galley designed for the product of that process. The first keyboard-actuated typesetting machines to be widely accepted, the Linotype and the Monotype, were introduced in the 1890s.
The Ludlow Typograph Machine, for casting of type-high slugs from hand-gathered brass matrices, was first manufactured in Chicago in 1912 and was widely used until the 1980s. Many are still in use and although no longer manufactured, service and parts are still available for them.
The Elrod machine, invented in 1920, casts strip material from molten metal; leads and slugs that are not type-high used for spacing between lines and to fill blank areas of the type page.
After a galley is assembled to fill a page's worth of type, the type is tied together into a single unit so that it may be transported without falling apart. From this bundle a galley proof is made, which is inspected by a proof-reader to make sure that the particular page is accurate.
