Siderography is a mechanical process developed by Jacob Perkins in the early 1800s enabling the unlimited reproduction of engraved steel plates. [1] The process enables the transfer of an impression from a steel plate to a steel cylinder in a rolling press. [2] An individual who engraves steel plates was known as a siderographist in the mid 1800s, [2] and a siderographer by the early 1900s. [3]
Perkins developed the use of steel plates in banknote production in 1805, and these were more resistant to wear from printing than copper plates. [1] Siderography enabled the steel plates to be copied with greater frequency. [1] It was first used for printing banknotes of the United States dollar. [1]
Counterfeiting had become an important issue in Europe in the late 1700s and early 1800s, primarily because the banknotes were produced with no standardized process or design, using readily available technology and techniques familiar to over 10,000 copper engravers. [4] France offered a prize contest in the 1790s as a result of the counterfeiting of assignats. [5] One of the submitted proposals for this contest had been the use of siderography, though it was not viable at the time. [1]
The English banknotes of that era came to be known as "filthy rags", [6] [7] and in 1817, the Bank of England advertised a contest for the submission of a process to develop counterfeit-resistant banknotes, for which the winning entry would receive £ 20,000. [8] Perkins moved to England in 1818, and made preparations for equipment, machinery, and his workmen to follow him. [8] He submitted his proposal for the use of siderography in banknote production, but the idea was not well received by the Bank of England. [1] Despite this, the idea gained traction, and by the end of the 1920s siderography was in use by over 200 banks in the United Kingdom. [1]
By the 1930s, a transfer press was operated by a siderographer, who would manipulate a "system of compound levers" on the press to regulate the amount of pressure exerted on the transfer rolls. [9]
On 11 January 1899, the Steel Plate Transferrers' Association trade union was established in Washington, D.C., which by 1921 had changed its name to the International Association of Siderographers. [3] It was the smallest organization by membership in the AFL–CIO (American Federation of Labor and Congress of Industrial Organizations), reaching a peak of about 80 members in the 1930s, and was dissolved in 1991 after retirements and technological advances reduced its membership to eight people. [10] [11]
It had three local chapters: the Washington office had jurisdiction for membership in that city, and all members outside the United States excluding Canada and Great Britain; the New York office had jurisdiction for all members in the United States excluding Washington, D.C.; and the Ottawa office had jurisdiction for all members in Canada and Great Britain.

Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article.
A banknote is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities.
Messrs. Perkins, Bacon & Co was a printer of books, bank notes and postage stamps, most notable for printing the Penny Black, the world's first adhesive postage stamps, in 1840.
Counterfeit money is currency produced without the legal sanction of the state or government, usually in a deliberate attempt to imitate that currency and so as to deceive its recipient. Producing or using counterfeit money is a form of fraud or forgery, and is illegal. The business of counterfeiting money is almost as old as money itself: plated copies have been found of Lydian coins which are thought to be among the first Western coins. Before the introduction of paper money, the most prevalent method of counterfeiting involved mixing base metals with pure gold or silver. Another form of counterfeiting is the production of documents by legitimate printers in response to fraudulent instructions. During World War II, the Nazis forged British pounds and American dollars. Today some of the finest counterfeit banknotes are called Superdollars because of their high quality and imitation to the real US dollar. There has been significant counterfeiting of Euro banknotes and coins since the launch of the currency in 2002, but considerably less than that of the US dollar.
Intaglio is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print, where the parts of the matrix that make the image stand above the main surface.
Jacob Perkins was an American inventor, mechanical engineer and physicist. Born in Newburyport, Massachusetts, Perkins was apprenticed to a goldsmith. He soon made himself known with a variety of useful mechanical inventions and eventually had twenty-one American and nineteen English patents. He is known as the father of the refrigerator. He was elected a Fellow of the American Academy of Arts and Sciences in 1813.
The Confederate States dollar was first issued just before the outbreak of the American Civil War by the newly formed Confederacy. It was not backed by hard assets, but simply by a promise to pay the bearer after the war, on the prospect of Southern victory and independence. As the Civil War progressed and victory of the South seemed less and less likely, its value declined. After the Confederacy's defeat, its money had no value, and both individuals and banks lost large sums.
Steel engraving is a technique for printing illustrations based on steel instead of copper. It has been rarely used in artistic printmaking, although it was much used for reproductions in the 19th century. Steel engraving was introduced in 1792 by Jacob Perkins (1766–1849), an American inventor, for banknote printing. When Perkins moved to London in 1818, the technique was adapted in 1820 by Charles Warren and especially by Charles Heath (1785–1848) for Thomas Campbell's Pleasures of Hope, which contained the first published plates engraved on steel. The new technique only partially replaced the other commercial techniques of that time such as wood engraving, copper engraving and later lithography.
Waterlow and Sons Limited was a major worldwide engraver of currency, postage stamps, stocks and bond certificates based in London, Watford and Dunstable in England. The company was founded as a family business in 1810. It was acquired in 1961 by De La Rue.

The 1937 Canadian banknote series is the second series of banknotes of the Canadian dollar issued by the Bank of Canada. The banknotes were issued into circulation on 19 July 1937, at which time the Bank of Canada began gradually removing banknotes from the 1935 series from circulation. The $1000 banknote was issued several years later, as it was primarily used by chartered banks, which had a sufficient supply of the 1935 Series $1000 banknote.
Canadian Landscape is the third series of banknotes of the Canadian dollar issued by the Bank of Canada, first circulated in 1954. The banknotes were designed in 1952 following the accession of Elizabeth II to the throne after the death of her father George VI. The banknote designs differed significantly from the preceding 1937 Series banknotes, though the denomination colours and bilingual printing were retained. This series was followed by the 1969 Scenes of Canada series.
Scenes of Canada is the fourth series of banknotes of the Canadian dollar issued by the Bank of Canada. It was first circulated in 1970 to succeed the 1954 Canadian Landscape series and was followed by the 1986 Birds of Canada banknote series. This was the last series to feature a $1 bill, which was replaced by a $1 coin known as the loonie in 1987, although both the $1 bill and the loonie were produced concurrently for 21 months, from June 1987 to April 1989.
Nature printing is a printing process, developed in the 18th century, that uses the plants, animals, rocks and other natural subjects to produce an image. The subject undergoes several stages to give a direct impression onto materials such as lead, gum, and photographic plates, which are then used in the printing process.
Roller printing, also called cylinder printing or machine printing, on fabrics is a textile printing process patented by Thomas Bell of Scotland in 1783 in an attempt to reduce the cost of the earlier copperplate printing. This method was used in Lancashire fabric mills to produce cotton dress fabrics from the 1790s, most often reproducing small monochrome patterns characterized by striped motifs and tiny dotted patterns called "machine grounds".
George Baxter (1804–1867) was an English artist and printer based in London. He is credited with the invention of commercially viable colour printing.
Birds of Canada is the fifth series of banknotes of the Canadian dollar issued by the Bank of Canada and was first circulated in 1986 to replace the 1969 Scenes of Canada series. Each note features a bird indigenous to Canada in its design. The banknotes weigh 1 gram with dimensions of 152.40 by 69.85 millimetres. It was succeeded by the 2001 Canadian Journey series.
Charles Theodosius Heath was an English engraver, currency and stamp printer, book publisher and illustrator.
In early 18th century Colonial America, engravers began experimenting with copper plates as an alternative medium to wood. Applied to the production of paper currency, copper-plate engraving allowed for greater detail and production during printing. It was the transition to steel engraving that enabled banknote design and printing to rapidly advance in the United States during the 19th century.
William Holl, the elder (1771–1838) was an English engraver, thought to be of German background, and a political radical.
