A stereotype mold ("flong") being made

Seattle Daily Times, ca. 1900 Stereotype casting room of the, ca. 1900

In printing, a stereotype,[note 1] stereoplate or simply a stereo, is a solid plate of type metal, cast from a papier-mâché or plaster mould taken from the surface of a forme of type.[1]:stereotype The mould was known as a flong.[note 2]

Background [ edit ]

In the days of set movable type, printing involved placing individual letters (called type) plus other elements (including leading and furniture) into a block called a chase. Cumulatively, this full setup for printing a single page was called a forme. Ink was then applied to the forme, pressed against paper and a printed page was made. This process of creating formes was labour-intensive, costly and prevented the printer from using their type, leading, furniture and chases for other work. Furthermore, printers who underestimated demand would be forced to reset the type for subsequent print runs.

. . . while Nathaniel Hawthorne's publishers assumed that The Scarlet Letter (1850) would do well, printing an uncharacteristically large edition of 2,500 copies, popular demand for Hawthorne's controversial "Custom House" introduction outstripped supply, prompting Ticknor & Fields to reset the type and to reprint another 2,500 copies within two months of the first publication. Still unaware that they had an incipient classic on their hands, Ticknor & Fields neglected at this time to invest in stereotype plates, and thus were forced to pay to reset the type for a third time just four months later when they finally stereotyped the book.[3]:677

While stereotypes were useful in book publishing, it was in newspaper publishing that they came into their own. Books were normally printed not as single pages, but as set of multiple pages at a time. Thus a single volume 320 page book needed 40 stereos for an eight page imposition, or twenty stereos for a 16-page imposition. This contrasts with newspapers, where a Sunday edition of a major newspaper could require as many as 6,000 stereos.[4]:87[note 3]

Advantages of stereotypes [ edit ]

Stereotype offered the following advantages:

They allowed the printer to quickly distribute [note 4] his expensive type, thus reducing the amount of type he needed to keep. [3] : 676 In some cases, contracts with publishers required printers to keep type set up for anything up to six months in case further editions were needed. [note 5]

his expensive type, thus reducing the amount of type he needed to keep. In some cases, contracts with publishers required printers to keep type set up for anything up to six months in case further editions were needed. Facilitated the distribution of the set-up type. As stereos were far lighter and less fragile than formes full of type. This was particularly important for syndicated news services.

Facilitated the storage of set-up type. Stereos were far lighter and took up a lot less space than formes full of type. This meant that the printer did not have to set up the work again. Stereo plates could be stored for several decades. A large number of such stored stereotypes were melted down in 1916 in the UK in support of the war effort. [6] : 16 In 1910 for example, Hodder and Stoughton published G. A. Henty's Friends though Divided: A tale of the Civil War printing the book, apart from the preliminary pages, from the stereotypes used for the initial 1883 edition by Griffith and Farran. [7] : 78 The same stereos were used for reprinting in 1917 and in the 1920s. [7] : 80 When they sold a copyright to another publisher, publishers often sold the stereotypes as well. [7] : 105

In 1910 for example, Hodder and Stoughton published G. A. Henty's printing the book, apart from the preliminary pages, from the stereotypes used for the initial 1883 edition by Griffith and Farran. The same stereos were used for reprinting in 1917 and in the 1920s. When they sold a copyright to another publisher, publishers often sold the stereotypes as well. Enabled the printer to quickly set up the same text multiple times so that he could print a given text e.g. for a handbill, Several times on the same sheet of paper and then separate them. This was faster and cheaper than doing them individually.

Enabled the same text to be printed on multiple presses at the same time. Dalgin gives the example of one instance where thirty stereos were produced from a single flong for this purpose and states that there is no reason why more could not have not have been cast.[4]: 86

Invention [ edit ]

English sources often describe the process as having been invented in 1725 by William Ged, who apparently stereotyped plates for the Bible at Cambridge University before abandoning the business.[8] However, Count Canstein had been publishing stereotyped Bibles in Germany since 1712 and an earlier form of stereotyping from flong was described in Germany in 1702. It is even possible that the process was used as early as the fifteenth century by Johannes Gutenberg or his heirs for the Mainz Catholicon. Wide application of the technique, with improvements, is attributed to Charles Stanhope in the early 1800s. Printing plates for the Bible were stereotyped in the US in 1814.[9]:45-49

Moulding materials [ edit ]

The following have been used for moulding type to create stereos:

Clay. Invented by a French printer, Gabriel Valleyre in 1730. He pressed the set-up forme in clay or other earthy substance to make a reverse image, and then poured molten copper into the mould. His copies were not very good, due either to the clay he was using, or the softness of the copper. [2] : 20 However, the method was later revived, improved, and used by Government Printing Office in Washington. [10] : 46 Hoe & Company included a range of plant for use with the process in their 1881 catalogue. [11]

Plaster of Paris. Gress was already describing this as an old method that had been displaced by the papier-mâché or paper process in 1909. [12] : 25 . The plaster process can reproduce finer lines than the paper process, but has the disadvantage that the mould is broken to remove the stereo. [13] : 26 This was the process developed by Gad in 1725, where a plaster mould is made of the set-up type. [2] : 18 The process was perfected in 1802, but because there were relatively few books that needed repeated print-runs other than bibles or schoolbooks, the process did not come into widespread use for another two decades. [14] : 262 The Bank of England printed its notes using stereos from plaster moulds in 1816. [15] : 241 Lord Stanhope had invested a considerable sum of money in developing the process, and he then established and funded a stereotyping plant in London. [10] : 63 . However it was not a commercial success and faced considerable opposition from the printing trade. [10] : 65-66 . David noted that it was only with the introduction of the flexible and robust papier-mâché flong in the 1850 that led to the extensive use of stereotyping for book production.

Papier-mâché or paper or wet process. In this process, a number of layers of paper fastened together by a paste made from a range of ingredients, including glue or gum. The paste could be to the stereotyper's own recipe or a proprietary paste. [12] : 29 Partridge describes the process as: A few sheets of thin paper are soaked in water until soft and then pasted together to form a flong. This flong is beaten into a page of type and dried, thus forming a matrix to receive the molten metal, which, when cooled, becomes an exact duplicate of the type page. A large number of duplicate casts may be made from the same matrix, either in flat form as required for flat-bed presses, or curved to fit the cylinders of rotary presses. [16] : 17 Gress notes that when first introduced The Times only made papier-mâché flongs of individual columns, but that Charles Craske of the New-York Tribune developed the method to make flongs of entire pages. [12] : 200

Dry mat, or dry matrix process. Here there is no need to beat the matrix into the page of type, but simple pressure is enough. The pressures needed are quite high[17]: 33 and effectively require a hydraulic press. By 1946, the dry mat process had completely taken over in newspaper publishing in the United States.[4]: 72

The process for making moulds for electrotypes was similar, except that these were made with soft materials such as beeswax or the naturally occurring mineral wax ozokerite.[18]:34 The thin electrotype shells had to be backed with type metal to a depth of 8mm make them robust enough for use.[18]:54

Making the stereotypes [ edit ]

After moulding the stereotype it is carefully removed from the mould. If the locking the flong into a moulding box, the box was pivoted so that the flong was in the vertical plane, and liquid type metal was poured into the mould. For newspapers these moulds were cylindrical in shape. This quickly cooled, and the mould was opened to remove the stereo. The stereo might be cooled further. The back of the stereo was then shaved, to reduce it to the required thickness for the press. The stereo was also trimmed and had the edges bevelled (to enable the stereo to be camped into place). The stereos where then clamped into place on the printing cylinder, and the print run began.

Type metal is an alloy of lead, tin, and antimony. Lead on its own makes type too soft to be of use. Tin was added to lead to make it harder, but the results were unsatisfactory. It was found that adding both tin and antimony led to type that was hard, resistant to wear and to distortion under pressure, and gave sharp reproductions.

The lowest solidification point for a liquid lead, antimony, and tin alloy occurs when the antimony content is twelve percent, known as the eutectic alloy.[19]:14[note 6] Keeping the antimony content close to twelve percent ensured the lowest possible melting point, important for slug-casting machines which melted an alloy ingot for casting the slugs. Low melting point is also important for the metal used for stereos as very high temperatures would damage the flongs. The type metal used for stereos was slightly different from the type metal used for foundry type, slug casting machines like the Linotype machine, individual letter casting machines as in the Monotype machine, or the metal used for backing electrotypes. While increasing the antimony content increases hardness, the tin content must be increased in proportion to achieve this.

Fry's offered the following guide to type metal for different uses.[19]

Composition of type metal alloys for different uses Intended use of the type metal Tin % Antimony % Lead 2% Notes Backing for electrotypes 2-4 2-4 92-96 [19]: 52 [note 7] Slug casting machines such as the Linotype 3.5-4 11.5-12 84-85 [19]: 33 [note 8] Stereotype plates 5-10 15 75-80 [19]: 44 Type casting machines such as the Monotype 6-13 15-19 68-81 [19]: 37 Foundry type metal for manual type-casting 13-22 20-28 50-67 [19]: 42

The golden rule for stereotyping was to have cool metal and a hot box to avoid problems with shrinkage cavities or sinks. Sometimes a casting board was used to slow the cooling at the back of the casting, as this could help to avoid problems due to the flong being a poor conductor. [19]:48-49

Scale of stereotyping [ edit ]

In 1946, Dalgin stated that the New York Times had one hundred slug-casting machines They consumed eight tons of type metal a night. However the stereotype department was casting seven times as much metal with a consumption of 45 tons of type metal every night and 150 tons on Saturday (for the large Sunday edition). They cast as many as 6,000 plates for the Sunday edition.[4]:87.

Not only that, but the time limit for composition to press-printing time was only 15 minutes. The last pages (typically the front page and pages with stories running on from the front page) were locked-up in their formes, and then the team had fifteen minutes to mould the matrices, the stereos cast, shaved, trimmed, cooled, and placed on the presses all in that fifteen minutes.[4]:90 Kjaer reported that the time from delivery of a forme to the stereotype foundry to onward delivery of a plate to the press room had fallen fomr eight minutes in 1916 to four minutes in 1926.[15]:6

Newspaper syndication and stereotypes [ edit ]

Initially syndicated news took the form of distributing printed sheets. In December 1841 the owner of the New York Sun had the then US president's address to congress couriered to him. He then printed it on a single sheet, and sold the sheets to newspapers in the surrounding regions, keeping the body, but changing the title head to suit the newspapers. The next effort was to have sheets printed with the president's address on one side and local news on the other.[10]:318[note 9] However, matters improved with improvements in stereotyping and the table summarised Kubel's relation of the growth of stereotyping for syndication.[10]:324

Period Method of distribution of syndicated materials Up to 1850 Via printed sheets, with either one or both sides printed 1850-1883 Via printed sheets and stereotype plates Fom 1883 Largely via stereotype plates From 1895 Flongs began to replace plates By 1941 Flongs had almost completely replaced plates

The flongs distributed were not just syndicated articles or comic strips, but also advertisements. This had a huge advantage in that newspapers avoided the costs of setting these up in type. In some cases flongs were distributed with sections that could be cut out where a local store name could be inserted, so that an illustrated advertisement for a particular product could include the name of the local dealer.[21] Newspapers combined a set of flongs to cast the stereotype plate for a page. In some cases, newspapers would cast a flong, combine that plate with other elements on a page, and then cast a second flong of the whole page, so the process went: Typeset-Flong of section-cast plate of section-combine plates to make a full page -> flong of full page -> plate of full page.

Death of the process [ edit ]

Stereotyping was first challenged by electrotyping, which was more expensive and time consuming, but was capable of higher quality printing. It was initially reserved for making copper facsimiles of illustrations. With time, Weedon states that in book publishing, it became more important than stereotyping.[6]:73 However, Kubler stated, in 1941, that in contrast to the United States, which made greater use of electrotyping, European plants used stereotype plates of 75% of all letterpress reproduction work, and that the best stereotype work as equal to the best electrotype work.[note 10] However, stereotyping retained its primacy in newspaper publishing. Kubler states that alternatives to stereotyping either involved significant additional capital costs or were unsuited for newspapers as they did not allow corrections and the insertion of late news and local materials or were both expensive and unsuitable.[note 11][note 12] The first computer-aided typeset book in the UK was Dylan Thomas' Collected Poems in 1966, but the process really took off in the 1970s, creating enormous disruption in the newspaper industry.[22]

The introduction of Offset printing meant that hot-metal type was no longer needed, and phototypesetting replaced the hot-metal type machines. This meant that there was no longer a need for stereotypes. The phototypesetting machines were replaced in their turn by the personal computer and desktop publishing. Kubler's firm that made dry mats dissolved on 13 August 1979.[23]

Etymologies [ edit ]

Over time, stereotype became a metaphor for any set of ideas repeated identically or with only minor changes. In fact, cliché and stereotype were both originally printers' words, and in their printing senses became synonymous. However, cliché originally had a slightly different meaning, being an onomatopoeic word for the sound that was made during the process of striking a block into molten type metal[1]:cliché during another form of stereotyping, later called in English "dabbing".[24]

The term stereotype derives from Greek στερεός (stereós) "solid, firm"[25] and τύπος (túpos) "blow, impression, engraved mark"[26] and in its modern sense was coined in 1798.

Writings on stereotyping [ edit ]

George Adolf Kubler (1876 – 9 January 1944)[27][note 13] was probably the person who wrote most about the process. He was the founder and president of Certified Dry Mat Corporation.[note 14] The firm made stereotype matrices or flong mats, which were used to first take a mould from the set-up type, and then to cast the stereotype plates. His writing included:
