Papierfabrik Louisenthal,
The Louisenthal Paper Mill, or Papierfabrik Louisenthal (PL) in regional language, is a manufacturer of security paper. Founded in 1878, the company has been a subsidiary of Giesecke+Devrient since 1964 which is best known as a manufacturer of banknotes. History In 1878, a paper mill was established in Gmund am Tegernsee. Since 1964, the company has been a subsidiary of Giesecke+Devrient. The company owns a second factory at Königstein, Saxony, acquired in 1991 after the German reunification. Manufacturing The substrate bears essential security features of banknotes to protect against counterfeiting. In the early days of banknote production, security paper was equipped with real watermarks and security threads. In 1994 the world's first banknote paper with hologram stripes was produced in Louisenthal (the 2000 leva banknote for Bulgaria). After plastic banknotes could not establish themselves on the market, the mill brought a banknote onto the market in 2008 which combined ...

Bulgarian Lev
The lev ( bg, лев, plural: / , ; ISO 4217 code: BGN; numeric code: 975) is the currency of Bulgaria. In old Bulgarian the word "lev" meant "lion", the word 'lion' in the modern language is ''lаv'' (; in Bulgarian: ). The lev is divided in 100 ''stotinki'' (, singular: , ). Stotinka in Bulgarian means "a hundredth" and in fact is a translation of the French term "centime". Grammatically the word "stotinka" comes from the word "sto" (сто) - a hundred. Since 1997, the lev has been in a currency board arrangement with initially the Deutsche Mark at a fixed rate of BGL 1000 to DEM 1. After the introduction of the euro and the redenomination of the lev in 1999, this has resulted in a fixed rate to the euro of BGN 1.95583 : EUR 1. Since 2020, the lev has been a part of the European Exchange Rate Mechanism (ERM II). The lev is scheduled to be supplanted by the euro on 1 January 2024. Etymology The currency's name comes from the archaic Bulgarian word "lev," which meant "lionh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banknotes
A banknote—also called a bill (North American English), 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 (usually gold or silver coin) 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. National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance is ...

Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label=Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optically Variable Ink
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. 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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Printing
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. A number of technical methods are used in the security printing industry. Security printing is most often done on security paper, but it can also occur on plast ...

Hybrid Paper-polymer Banknote
A hybrid paper-polymer banknote or Composite Substrate is a banknote made from a mixture of paper and polymer substance. Hybrid banknotes are essentially a paper banknote with a polymer patch. A polymer patch/band is applied vertically over the entire height of paper banknote, thus creating a clear window. The height of the polymer window generally measures 74 mm depending on the height of the banknote × 16 mm. Its thickness is 25 microns. Bulgaria was the first country to produce a hybrid paper polymer banknote, in a denomination of 20 Bulgarian Leva in 2005.Manufactures of hybrid banknotes include Giesecke+Devrient's Hybrid and Varifeye, De La Rue's Optiks, Louisenthal's Hybrid, Landqart AG's DuraSafe and Banque de France's EverFit. The countries which use hybrid banknotes include: Gallery File:Tajikistan 500 Somoni observe.jpg, Tajikistan 500 Somoni in G+D's Hybrid File:100 Olympic rubles.jpg, Russia 100 Ruble commemorating 2014 Winter Olympics.

Polymer Banknote
Polymer banknotes are banknotes made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). Such notes incorporate many security features not available in paper banknotes, including the use of metameric inks. Polymer banknotes last significantly longer than paper notes, causing a decrease in environmental impact and a reduced cost of production and replacement. Modern polymer banknotes were first developed by the Reserve Bank of Australia (RBA), Commonwealth Scientific and Industrial Research Organisation (CSIRO) and The University of Melbourne. They were first issued as currency in Australia during 1988 (coinciding with Australia's bicentennial year); by 1996, the Australian dollar was switched completely to polymer banknotes. Romania was the first country in Europe to issue a plastic note in 1999 and became the third country after Australia and New Zealand to fully convert to polymer by 2003. Other currencies that have been switched completely to polymer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hologram
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other Holography#Applications, applications. In principle, it is possible to make a hologram for any type of Holography#Non-optical holography, wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be Computer-generated holography, computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest. Overview and ...
