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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Euro Banknotes
Banknotes of the euro, the common currency of the eurozone (euro area members), have been in circulation since the first series (also called ''ES1'') 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 Euro coins, coins began to circulate. The euro rapidly took over from the former national currencies and slowly expanded around the European Union. Denominations of the notes range from €5 to €500 and, unlike euro coins, the design is identical across the whole of the eurozone, although they are issued and printed in various member states. The euro banknotes are pure cotton fibre, which improves their durability as well as giving the banknotes a distinctive feel. They have a variety of color schemes and measure from to (first series) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Glitter
Glitter is an assortment of flat, small, reflective particles that are precision cut and come in a variety of shapes, sizes, and colors. Glitter particles resemble confetti, sparkles and sequins, but somewhat smaller. Since prehistoric times, glitter has been made from many different materials including stones such as malachite, and mica, as well as insects and glass. Uses for glitter include clothing, arts, crafts, cosmetics and body paint. Modern glitter is usually manufactured from the Metallised film, combination of aluminum and BoPET, plastic, which is rarely recycled and can find its way into aquatic habitats, eventually becoming ingested by animals, leading some scientists to call for bans on plastic glitter. Antiquity Glittering surfaces have been found to be used since prehistoric times in the arts and in cosmetics. The modern English word "glitter" comes from the Middle English word ''gliteren'', possibly by way of the Old Norse word ''wikt:glitra, glitra.'' Howeve ...

Pearlescent
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of the go ...
