printing
printing with movable types, or letterpress, as opposed to printing using carved wooden blocks, was invented by Johannes Gutenberg of Mainz c.1440, though there is evidence that a Dutchman, Coster of Harlem, made a similar breakthrough about the same time. One of Gutenberg's associates, Peter Schoffer, produced a psalter in 1457, the first known book with a printed date. In 1462 the sack of Mainz dispersed printers and their equipment, the process being introduced to England by William Caxton in 1476. It did not reach Scotland until 1507 when the first printing press was set up in Edinburgh by Walter Chapman and Andrew Myllar.
Early printers used a wooden press, types, paper, and ink. The primitive press, constructed of wood and iron, was a screw press resembling a wine or cloth press. The plate, or ‘platen’, was applied by a vertical screw, hand operated by a lever, to the printing surface, or ‘forme’, placed horizontally on the bed of the press. Ink was applied to the type by dabbers, known as ink balls, a technique which survived until the development of the ink roller at the beginning of the 19th cent. Printers at first made their own types, but typefounding, an early instance of mass production, soon became a separate trade. Although many improvements were made, the process remained essentially the same until the early 19th cent.
Printing and publishing, which were closely allied, grew slowly until the latter half of the 18th cent. This was partly due to censorship, which intermittently constrained publication, and partly to the high cost of paper, which was also heavily taxed. While censorship continued until the early 19th cent., paper became cheaper and could be produced in continuous sheets following the introduction of paper-making machines developed in France by Nicholas Louis Robert (1798) and Henri Fourdrinier (1806). John Dickinson, an English paper-maker, patented the first cylinder machine in 1809. Paper could thus be produced in larger sizes and greater quantities than by hand.
The 19th cent. also brought significant developments in the industrialization of printing itself. Lord Stanhope developed the first all-metal platen press in 1804. At the same time the screw mechanism was improved, resulting in greater and more even pressure on the forme, and the ink roller greatly increased the speed of production. The improved Stanhope press doubled the output of the traditional wooden press. Even greater gains in productivity were made following the introduction of the first practical mechanized printing press developed by Friedrich Koening in 1811. It was designed to feed single sheets of paper through a cylinder press and in 1814 was modified for The Times, to become a two-feeder machine printing on both sides of the paper at once. The first power-driven platen press was developed about 1822.
The Times continued to lead the field with a steam press, producing 5,000 copies per hour, in 1827. Another important breakthrough was the rotary press with types fastened round a cylinder, introduced in 1848, and, after a further period of development, the continuously running rotary press, where a stereotyped printing surface was attached to the cylinder, pioneered at The Times in 1868. With subsequent refinements, this remained the standard method of newspaper-printing for over a century.
Pictorial reproduction was greatly influenced by the development of photography. Wood blocks and wood engravings, the commonest means of illustration, were gradually replaced by the photo-engraved line block and later by the half-tone block in which gradations of tone were simulated by typographic dot-formations of varying pattern and size. The monochrome half-tone process, introduced in 1872, was refined by the end of the 19th cent. to allow full colour reproduction. Similar technology was adopted in the book-printing trade.
Composing methods, using movable type, underwent a parallel revolution with the development, initially in the USA during the 1880s, of composing and casting machinery operated from keyboards. For nearly a century, the text to be printed was cast in hot metal, using monotype to set single characters or linotype to set text line by line. Thus, despite mechanization, printing remained a skilled occupation and historically a highly unionized craft, notably in the newspaper industry, which expanded dramatically in the early 20th cent.
Consequently the print unions had a long history of confrontation with the press barons. The printers' solidarity was threatened and ultimately undermined during the 1970s and 1980s by a move away from hot metal to computerized typesetting using high-speed optical methods and electronic page make-up systems. The introduction of new technology led to dramatic rationalization and to redundancies in printing and related trades. In London, bitter strikes and lock-outs resulted from the movement of newspaper printing from its traditional heartland in Fleet Street to new production units in the East End. Elsewhere in newspaper-printing, notably in Manchester and Glasgow, similar effects were felt. Book-printing, like publishing, was also transformed by the new technology. Printing has always had important backward linkages to paper manufacture and the metal trades, and, with increasing mechanization during the 19th cent., to engineering. It was also closely linked after the mid-18th cent. to the development of publishing, of both books and newspapers.
