c 594: The Chinese began to practice printing from a negative relief. Their method of rubbing off impressions from a wood block spread along the caravan routes to the West. From China also came the invention of paper which was to provide the ideal surface for printing.
c 1400: The technique of printing with wooden blocks arrived in Europe from the Far East.
c 1450: Johann Gutenberg adapted the screw printing press from the wine presses which had been used in the Rhine Valley since the days of the Roman Empire. He used a recently perfected oil-based ink and devised a mould of metal prism matrices, punch-stamped typeface moulds and invented a functional metal alloy to mould the type.
c 1460: Printer's ink invented only fifteen years after the first use of oil paints for pictures. It had to be able to stick onto a metal surface and it was based on heat-bodied linseed oil, kept for a year to allow the mucilage to settle. Resin may then have been added. The black pigment would have made from the soot collected from burning pitch and then roasted it several times the get rid of the tarry oils. Many printers were still making their own ink as late as 1850.
1500s: Printing provided the first mass medium vehicle for advertising and in the 1500s printed handbills began to replace the town criers.
1600s: The screw press was improved for the first time since Gutenberg's day with the introduction of springs to aid the platen to lift rapidly. It was then able to print a maximum of 250 impressions an hour. Newspapers began to appear. The relationship between advertising and newspapers enabled both to flourish from the early 17th century. The printed medium changed advertising from announcements to persuasion.
1799: Printing by lithography was invented by an Austrian printer Alois Senefelder. He found that he could print from the flat, smooth, surface of fine-grained limestone. In the 19th century lithography became the preferred method for reproducing quality illustrations for books and magazines in both colour and monochrome.
1803: Machine made paper begins to replace hand-made paper. The first practical paper machine was invented by Nicholas Louis Robert at the Essonnes Mill, France, but the patent was taken to England where the first efficient machines were set up. Paper was mainly produced from linen and cotton rags. Esparto grass was also used.
1804: The third Earl of Stanhope (1753-1816) replaced the wooden screw press, virtually unchanged since Gutenberg's time, with an iron framed lever press. The press used by Andrew Bent, now at the TMAG, to publish his Hobart Town Gazette and Van Diemen's Land Advertiser in the early 1820s is Stanhope's improved model of 1807.
1805: Lord Stanhope also introduced stereotyping, which made the saving of pages of type for reprinting a commercial proposition. Pages of type for future reprints were preserved using plaster or metal matrices from which a stereotype could be cast, instead of having to reset the text.
1814: Frederich Koenig's steam printing machine with rollers was adopted by The Times, London, in 1820, and raised the output of a printing press from 300 to 1100 copies an hour.
1822: The letter founding machine, invented by Dr William Church and a forerunner to the linotype machine, raised the number of letters that could be cast daily from 3,000 / 7,000 to 12,000 / 20,000.
1827: The New Press of Applegath and Cowper enabled The Times to produce 5,000 copies an hour from a single machine. Prior to this rows of Stanhope presses had been used.
1829: The stereotyping process improved. Clumsy plaster and metal matrices were replaced by papier mache ones, reducing labour, weight and bulk in storage. 1831 - French engineer Gaveaux designed a two-cylinder version of the New Press which handled the paper better and further increased production.
1840: American Richard March Hoe developed a revolving perfecting press which could turn out 20,000 impressions an hour. The manufacture of paper from wood pulp was accomplished this year and within a decade production had spread everywhere. The outward appearance and 'feel' of paper was altered and it became much cheaper to produce, which was particularly advantageous to newspaper production.
1846: Hoe developed the first version of a rotary press. He found a way to fit the type around the cylinder which was inked by automated rollers while four smaller rollers brought the sheets of paper in contact with it. This raised the number of impressions that could be taken from 22,000 to 24,000 an hour.
1853: Claude Genoux and Nicholas Serriere improved the system for making page moulds on papier mache flongs, as they came to be called. A flong prepared from flat type could be curved to permit moulding of the cylindrical type needed for a rotary press. Flongs were used until recent times when the introduction of offset presses and computer technology revolutionised the printing process.
1854: James Gordon Bennett in his New York Herald developed a method using a metal plate impression of the type rather than the type itself.
1859: Photo-lithography. A French lithographer, Firmin Gillot, developed a new method for etching metal plates. In 1872 his son invented zincography, which combined photography with etching so that the resulting picture could be sized up and down as required. But it was limited to uniform black on white. By 1880 a method of producing intermediate tones was devised by a system of dots of different sizes. By the end of the century photo-lithography had become a new branch of the journalistic profession. Photo-lithographic 'block' making in zinc was performed until photo-composition in the 1970s.
1863: William Bullock perfected a method of feeding paper into a machine continuously instead of by sheets. He also incorporated Bennett's metal plate system and the use of stereotypes, shaped to fit the rollers, instead of hand set type.
1885: Linotype and Monotype machines were developed. Between 1815 and 1871 seventy attempts had been made to create a machine capable of setting type and adjusting the spacing of words. A machine that did this work, the Linotype was developed by Ottmar Mergenthaler in America who was inspired by a punch-cutting machine invented in Milwaukee by Linn Boyd Benton.
1889: Hippolyte Marinoni at the Paris Exposition demonstrated a rotary press which turned a roll of paper back on its path, enabling successive sheets of large and small size to be printed on both sides and then cut and folded into piles of completed newspapers, the whole operation performed at great speed.
1890: By now there was a wide choice of fast rotary presses to choose from. Each had its own specialised technology. The great advances in newspaper production technology were over until the development of web offset printing and photo-composition in the 1970s.
