Optically variable ink (OVI) also called color shifting ink is an anti-counterfeiting measure used on many major modern banknotes, as well as on other official documents (professional licenses, for example).
The ink displays two distinct colors depending on the angle the bill is viewed at. The United States fifty-dollar bill, for example, uses color shifting ink for the numeral 50 so that it displays copper at one angle and bright green in another. [1]
OVI is particularly useful as an anti-counterfeiting measure as it is not widely available, and it is used on security printing. One major manufacturer is a Swiss company called SICPA (Société Industrielle et Commerciale de Produits pour l'Agriculture). Additional suppliers include German company Gleitsmann Security Inks, Sun Chemical (through their Brand Protection Division based in Manchester, UK), and the Swiss company Printcolor AG, located in Berikon, Switzerland.
Color-shifting inks reflect various wavelengths in white light differently, depending on the angle of incidence to the surface. An unaided eye will observe this effect as a change of color while the viewing angle is changed. A color copier or scanner can copy a document only at one fixed angle relative to the document's surface. [2] It uses finely powdered pearlescent glitter.
Optically variable magnetic ink (OVMI), also called SPARK, [3] has visual effects that are based on the magnetic properties of the ink. When the document is tilted, movement of a bright light stripe occurs and the colour changes. It is usually applied by screen printing. This type of ink is used for the Euro, [4] Brazilian real, [5] and Russian ruble banknotes. [6]
Federal Reserve Notes, also United States banknotes, are the currently issued banknotes of the United States dollar. The United States Bureau of Engraving and Printing produces the notes under the authority of the Federal Reserve Act of 1913 and issues them to the Federal Reserve Banks at the discretion of the Board of Governors of the Federal Reserve System. The Reserve Banks then circulate the notes to their member banks, at which point they become liabilities of the Reserve Banks and obligations of the United States.
A banknote—also called a bill, paper money, or simply a note—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.
The South Korean won is the official currency of South Korea. A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea, based in the capital city of Seoul.
The Namibia dollar has been the currency of Namibia since 1993. It is normally abbreviated with the dollar sign ($), or alternatively N$ to distinguish it from other currencies called “dollar.” It is divided into 100 cents.
The United States one-hundred-dollar bill (US$100) is a denomination of United States currency. The first United States Note with this value was issued in 1862 and the Federal Reserve Note version was first produced in 1914. Inventor and U.S. Founding Father Benjamin Franklin has been featured on the obverse of the bill since 1914, which now also contains stylized images of the Declaration of Independence, a quill pen, the Syng inkwell, and the Liberty Bell. The reverse depicts Independence Hall in Philadelphia, which it has featured since 1928.
Security printing is the field of the printing industry that deals with the printing of items such as banknotes, cheques, passports, tamper-evident labels, security tapes, product authentication, stock certificates, postage stamps and identity cards. The main goal of security printing is to prevent forgery, tampering, or counterfeiting. More recently many of the techniques used to protect these high-value documents have become more available to commercial printers, whether they are using the more traditional offset and flexographic presses or the newer digital platforms. Businesses are protecting their lesser-value documents such as transcripts, coupons and prescription pads by incorporating some of the features listed below to ensure that they cannot be forged or that alteration of the data cannot occur undetected.
The tögrög or tugrik is the official currency of Mongolia. It was historically subdivided into 100 möngö. Currently, the lowest denomination in regular use is the 10-tögrög note, and the highest is the 20,000-tögrög note. In Unicode, the currency sign is U+20AE₮TUGRIK SIGN.
Counterfeit money is currency produced outside of the legal sanction of a 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 in all jurisdictions of the world. The business of counterfeiting money is nearly 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 of 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.
A currency detector or currency validator is a device that determines whether notes or coins are genuine or counterfeit. These devices are used in a wide range of automated machines, such as retail kiosks, supermarket self checkout machines, arcade gaming machines, payphones, launderette washing machines, car park ticket machines, automatic fare collection machines, public transport ticket machines, and vending machines.
ChromaFlair is a pigment used in paint systems, primarily for automobiles. When the paint is applied, it changes color depending on the light source and viewing angle. It was created at Optical Coating Laboratory, Inc. (OCLI) [later JDS Uniphase and Viavi Solutions] in 1979 and is used by DuPont and PPG.
The fifth series of the renminbi is the current coin and banknote series of the Chinese currency, the renminbi. They were progressively introduced since 1999 and consist of ¥0.1, ¥0.5, and ¥1 coins, and ¥1, ¥5, ¥10, ¥20, ¥50, ¥100 notes. The ¥20 banknote is a new denomination, and was added in this series. All banknotes in this series feature a portrait of Chinese Communist Party chairman Mao Zedong by artist Liu Wenxi. Therefore, this series of banknotes is also known as "Grandpa Mao" among the people.
Security paper is a paper used in security printing that incorporates features that can be used to identify or authenticate a document as original, e.g., watermarks or invisible fibres in paper, or features that demonstrate tamper evidence when fraud is attempted, e.g., to remove or alter print such as amounts or signatures on a cheque. Examples of this kind of papers are used for banknotes and used for identification such as passports and certificates, such as birth certificates and different types of academic and qualification certificates, as well as government documents, e.g., voting ballots and tax strips. This also extends to personal and business checks, stock certificates, certificates issued by financial institutions and sensitive government-issued documents. The main use of security paper is to stop people from counterfeiting.
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.
Banknotes of the euro, the common currency of the eurozone, have been in circulation since the first series was issued in 2002. They are issued by the national central banks of the Eurosystem or the European Central Bank. The euro was established in 1999, but "for the first three years it was an invisible currency, used for accounting purposes only, e.g. in electronic payments". In 2002, notes and coins began to circulate. The euro rapidly took over from the former national currencies and slowly expanded around the European Union.
The fifty euro note (€50) is one of the middle value euro banknotes and has been used since the introduction of the euro in 2002. The note is used by some 343 million Europeans and in the 25 countries which have the euro as their sole currency. In July 2023, there were about 14,523,000,000 fifty euro banknotes in circulation in the eurozone. It is by far the most widely circulated denomination, accounting for almost half (49.0%) of the total banknotes. Estimates suggest that the average life of a fifty euro banknote is about four years before it is replaced due to wear.
An optical variable device or optically variable device (OVD) is an iridescent or non-iridescent security feature that exhibits different information, such as movement or colour changes, depending on the viewing and/or lighting conditions. The particular changes of appearance when rotating and tilting are reversible, predictable and reproducible. OVDs cannot be photocopied or scanned, nor can they be accurately replicated or reproduced. OVDs are often used as security devices and anti-counterfeiting measures on banknotes, government-issued identification documents, or credit cards. OVDs can be created through a combination of printing and embossing.
The Gandhi Series of banknotes are issued by the Reserve Bank of India (RBI) as the legal tender of Indian rupee. The series is so called because the obverse of the banknotes prominently display the portrait of Mahatma Gandhi. Since its introduction in 1996, this series replaced all Lion Capital Series banknotes issued before 1996. The Reserve Bank of India (RBI) introduced the series in 1996 with ₹10 and ₹500 banknotes.
The Indian 100-rupee banknote is a denomination of the Indian rupee. It has been in continuous production since Reserve Bank of India took over the functions of the controller of currency in India in 1935. The present ₹100 banknote in circulation is a part of the Mahatma Gandhi New Series.
SICPA is a Swiss company that provides security inks for currencies and sensitive documents, including identity documents, passports, transport and lottery tickets. According to the Counterfeiting Intelligence Bureau's International Anti-Counterfeiting Directory, SICPA provides more than 85% of the world's currency inks. The company is also involved in the market for secure traceability of products subject to excise duties, such as alcohol and tobacco stamps, and regulated products, such as halal products.
A diffractive optically variable image device (DOVID) is a type of optical variable device; a security feature based on visual effects created by diffraction. The acronym was coined by Ian Lancaster of Reconnaissance International in 1995. He pointed out that the security print industry was wary of holograms and similar diffractive devices because they were used as decorative, promotional and toy items, proposing the use of DOVID as a means to differentiate security diffractive optical devices from these other uses.
