Security Features

SECURITY FEATURES

I. Substrate

When we look at a certain banknote, the first thing that comes to our eyes is often the substrate, i.e., the material on which the banknote is being printed. Unlike the regular banknotes we use in everyday life, banknotes issued by micronations usually adopt rather simpler materials in order to facilitate the printing process and also reduce its costs, albeit some micronations also use specialized materials to enhance the aesthetics of their banknotes or as a security measure against counterfeiting. To summarize, these substrates can be briefly categorized into two braod groups, i.e., paper and polymer, whereas either group consists of a series of slightly different variants.

Matte paper: In terms of paper types, matte paper has been adopted by the vast majority of the micronational community as the banknote substrate due to its ubiquity and cheapness. This refers to not only the multipurpose plain paper that we use on a regular basis for copying and printing, but also any types of colored paper, sticker paper, cardboard, etc., that comes with a dull finish (i.e., without a shine).
Coated paper: Contrary to matte paper, coated paper comes with a glossy finish and is often used for magazines and marketing materials. Some micronations choose to print their banknotes on coated paper as the product often has a brighter and much more contrasting color scheme than those printed on plain paper. Micronations that have used coated paper for their banknotes include Edristan, Frioul, etc.
Laid paper: Sometimes considered as a type of watermarked paper, laid paper refers to the type of paper with a ribbed texture (i.e., with horizontal or vertical lines), which can often been seen when held against light. Laid paper is typically used for high-quality invitations and business cards, and may come with real watermark revealing its manufacturer, e.g., Conqueror®. Micronations that have used laid paper for their banknotes include Gordjan, Užupis, etc.
Linen paper: As the name suggests, linen paper refers to the type of paper having a texture resembling that of linen fabric (i.e., with horizontal and vertical lines). Unlike laid paper, the linen-like texture of linen paper is not reflected through watermark, but only through the finish of the paper, even though it may still come with watermark of the manufacturer. Linen paper is often used for gift wrapping, as well as high-quality envelopes and book covers. Micronations that have used linen paper for their banknotes include Boshka, Molossia, etc.
Parchment: Parchment paper refers to a type of high-quality paper that is made to look like real parchment. Used primarily for artistic purposes, it often has a brown to beige color as well as a relatively coarse finish. Micronations that have used parchment paper for their banknotes include Evrugo, Tír na nÓg, etc.
Other types of specialty paper: Apart from the types of paper discussed above, a few micronations have also used specialty paper with other types of unusual texture for their banknotes. These include, for example, Fidelis (printed on specialty paper with a shiny and melon-like finish) and Saint-Castin (printed on specialty paper with a rough texture). For watermarked paper and security thread paper, see Sections III and IV below, respectively.
Teslin: TESLIN® is a special synthetic paper manufactured by PPG Industries that is often categorized as a particular type of polymer substrates. Most commonly used for product labels, Teslin is very similar to traditional polymer substrates in terms of its outstanding waterproof and tear-resistant quality. Micronations that have used Teslin for their banknotes include Atlantium, ISSA, etc.
Tyvek: Tyvek® is a type of durable and waterproof synthetic fiber manufactured by DuPont that is often used for festival wristbands, etc. Unlike Teslin, Tyvek was actually used in the 1970s for banknotes of Haiti, the Isle of Man, etc., as an early attempt of producing polymer banknotes before the commonly known polymer substrate was introduced later in Australia. The only micronation that has used Tyvek for its banknotes is Saugeais.
Polymer substrates: As with banknotes of macronations, those of micronations sometimes also adopt plastic, resin, or other polymer substrates for better durability and as an anti-counterfeiting measure. Earlier micronational attempts of polymer banknotes include those issued by the Republic of the Earth, Riviera, etc., whereas others have started to issue polymer banknotes in more recent years, e.g., Elleore and North Barchant.
Fabric: Under some rare circumstances, it is also possible for micronations to have banknotes made of cloth or textile, similarly to German notgeld from the WWI period. The only micronations that have ever produced banknotes in the form of fabric are Ivoire of NovaTroie and Zeta Auxvius of Kosgna. Resemling notgeld, these banknotes often tend to be emergency or souvenir issues that are not part of the regular banknote series.

II. Ink

While most micronations nowadays tend to print their banknotes with a normal inkjet printer, it is not rare for some of them to incorporate special inks as an additional security measure, especially those with a higher budget for their banknotes. Despite some subtle differences between brands, special inks can be generally described as either colored (iridescent ink and most types of fluorescent ink) or colorless (invisible ink), all of which are used rather frequently by micronations around the world.

Invisible ink: As its name suggests, invisible ink refers to a special type of ink that appears colorless under normal environment. Some types of invisible inks might already have a shiny effect under normal daylight, whereas others only reveal themselves through heat or ultraviolet light. Micronations adopting invisible inks for their banknotes include the GCWP, Hajduk Republic, etc.
Fluorescent ink: Although some types of fluorescent ink can be alternatively counted as invisible ink due to their invisibility in normal environment, most micronations tend to use a yellow fluorescent marker to achieve a similar effect at a much lower cost. Despite this difference, fluorescent ink always should always have a neon-like appearance when exposed to ultraviolet light. Micronations that have used fluorescent ink on their banknotes include Antnapolistan, Los Bay Petros, etc.
Iridescent ink: Iridescent ink refers to a type of colored ink that has a glittering and sometimes color-changing luster. Although other colors such as blue and green also exist, many types of iridescent ink come in gold or silver color, thus often used by micronations together with the stamping methods introduced in Section V. Micronations that have used iridescent ink on their banknotes include Edristan, UTNR, etc.
Iriodin: Iriodin® is a mica-based pearlescent ink manufactured by Merck KGaA that has a unique natural luster and color effect. On micronational banknotes, it often appears to be a geometric shape or pattern with a semi-transparent to silver-white coating. The only micronations that have used Iriodin on their banknotes are Kamberra (as well as banknotes produced by Kamberra for other micronations) and Nazland.

III. Watermark

A common security feature among all types of banknotes issued by macronations, watermark refers to a hidden image incorporated directly to the banknote paper that is visible only when it is held against light. Despite its relatively high cost, watermarked paper is also used by a number of micronations for their banknotes. It can be briefly categorized to the following three types: general watermark, local watermark, and fake watermark (i.e., hidden image).

General watermark: The watermark is repeated all over the banknote. While general watermark has become somewhat outdated for banknotes we use in daily life, it is often preferred by micronations as it is relatively easier and cheaper to acquire watermarked paper with general watermark. Typical patterns of general watermark include geometric shapes (as shown on banknotes from Alcatraz and Malu Entu), flowers (as shown on banknotes from Edristan and Kamberra), etc.
Local watermark: The watermark is not repeated and is only revealed on a specific area of the banknote, i.e., the watermark area, which is often purposefully left blank so that the watermark can be easily seen. While this is the most common type of watermark that we can see on US$ or Euro bills, not so many micronations choose to adopt it for banknotes, as such watermarked paper is often customized and can be extremely expensive for micronationalists. Those that have adopted local watermark for their banknotes include Kamberra, Reunion, etc.
Fake watermark: The hidden image is not a real watermark incorporated into the paper, but rather inscribed inside the banknote. Historically, it is best known for its presence on old Tibetan banknotes, which are made from two separate pieces of paper. The hidden text was first reversely inscribed on one of them, and then both pieces would be stuck together to form a real banknote. Kosgna and Yangina are the only two micronations using hidden image on their banknotes.

IV. Hologram & Security Stripe

Hologram: Hologram usually refers to a small piece of metallic foil or stripe bearing a certain pattern or image that glitters or even alters when viewed from a different angle. The holographic foil is often incorporated onto the substrate via a method known as hot stamping (see "Foil stamping" in Section V below), but this can be quite costly and require some professional works, thus only afforable for some micronations, such as Aigues-Mortes and Alcatraz. Instead, most micronations simply adopt ready-to-use holographic stickers as a more viable substitute for their banknotes, such as Boshka and Valbona.
Security thread: Fairly common among regular banknotes but less so among micronational ones, security thread refers to a thin metallic stripe that is embedded in paper during its manufacturing process. There are two major types of security threads: a latent security thread is completely hidden in banknote paper and can only be seen when it is held against light, whereas a windowed security thread already reveals itself partially on the surface of paper (resembling a dashed line), though it is visible in its entirety only when held against light as well. Micronations that have used security threads on their banknotes include Edristan, Kamberra, etc.
Security tape: Unlike security threads, which are completely incorporated into the banknote paper, security tape refers to a decorative band often stuck onto the surface of banknotes. This feature is only seen on banknotes issued by a handful of micronations, including Cosma, etc.

V. Stamping

Stamping often involves a special mark that is being pressed onto the banknote once it has been printed. While the mark pressed is usually an official seal or a date stamp, there is a wide variety of methods by which this mark can be applied to the substrate, from the most commonly seen ink stamping, embossing, to hot foil stamping, which requires a certain degree of professionalism.

Ink stamping: Outside micronationalism, ink stamps are already used ubiquitously on all kinds of official documents, etc. Apart from rubber stamps and self-inking stamps, for instance on banknotes of Geniusz and St.Charlie, it is also very common nowadays for micronations to apply a letterpress or computerized seal to their banknotes once the printing process is completed, such as on those of the GCWP and S.M.O.R.A. Furthermore, it is also very common to apply the method with iridescent ink (i.e., gold, silver, and bronze stamping), so that the seal would have shiny, often metallic effect. This is seen on banknotes of Beaulosagñe, NSK, etc.
Embossing: While ink stamping results in a mark that is colorful and flat, embossing refers to a method by which the substrate is being pressed via an embosser, thus leaving a colorless dry seal in relief. Micronations that have adopted the method of embossing for their banknotes include Molossia, Xenostrov, etc.
Raised pattern: Perhaps a combination of ink stamping and embossing, raised pattern refers to a special mark on substrate that is both raised, i.e., in relief, and often colored. Unlike embossing, raised patterns are not achieved by pressing, but rather through melting of a special type of ink powder, thus only visible from one side of the substrate. Micronations that have raised patterns on their banknotes include Kamberra, Litila, etc.
Foil stamping: Foil stamping or hot stamping refers to the process by which a sheet of metallic foil, often of gold or silver, is forced under heat and pressure to attach to the substrate, leaving a pressed seal that matches the design of the carved die that has initiated this process. Micronations that have adopted the method of foil stamping for their banknotes include the OWK, Riviera, etc.

VI. Other Add-on Features

A wide range of additional security measures can be applied to banknotes during designing and printing processes. Generally speaking, micronations tend to adopt simpler and more practical security features on their banknotes, the most frequently seen ones of which are as follows.

Clear window: While clear window usually refers to the transparent area on polymer banknotes that is not covered with any coatings, in terms of micronational banknotes, it is more likely to be a perforated area on banknote that is covered by a transparent layer of polymer or other similar materials. This feature is present on banknotes of Kosgna, North Barchant, etc.
Engraving: If we pull out a bill from our purse and try to touch the main design or any of the main text, we often feel that the ink on these areas is so thick that it produces relief similarly as embossing. Although extremely common with regular banknotes, this printing technique known as intaglio has never been adopted by any micronations for their banknotes due to the exceptional professionalism it would require. As a reasonable alternative, it is sometimes possible for micronations to at least have an engraved design, usually a portrait, on their banknotes, which however is still printed in the regular fashion. Banknotes designed by the Atlantic Bank Note Company and GabrisBanknote are famous for the professionally engraved portraits, for example those of Greifenberg and Seborga.
Lamination: Lamination refers to the method through which the paper substrate is covered by two welded sheets of transparent plastic films. Micronations that have adopted the method of lamination for their banknotes include Anthophilia, Wadonstol, etc.
Latent image: Latent image refers to a hidden image on banknote that consists of multiple parallel lines and can hardly be distinguished with naked eyes. This image is often revealed best when the banknote is being tilted. Micronations that have latent images on their banknotes include Atlantium, Kamberra, etc.
Microtext: Microtext or microprinting refers to the extremely small text or patterns printed on banknotes that are barely visible to naked eyes. Technically speaking, microtext must be so small that it can only be seen with a magnifying glass, such as on banknotes of the Kingdom of Time and Pinsk. However, micronational banknotes printed via a home printer often involve microtext that is significantly larger in size, such as those of Timucua and Tír na nÓg.
Omron rings: Omron rings or EURion constellation is a geometric pattern consisting of five circles that protects banknotes from being copied or printed by a normal printer. Micronations that have Omron rings on their banknotes include Duckionary, Illes Sant Jordi, etc.
Perforation: There are two different types of perforation seen among micronational banknotes - It can be either one single hole on banknote that has a particular form or shape, or a line or pattern formed by an array of much smaller holes. The former type of perforation is seen on banknotes of Litila, whereas the latter is seen on those of Kamberra and Landashir.
See-through register: See-through register refers to an image on banknote, a part of which is printed on one side of it and the rest printed on the other side. When the banknote is held against light, both parts would match up, thus forming a complete image. This technique is seen on banknotes issued by Reunion, Soundland, etc.
Serial number: Serial number refers to a unique combination of numbers (and sometimes letters, too) that is assigned to one and only one piece of banknote each time. It can be printed along with banknote itself, alternatively stamped or written on banknote after it has already been printed. Many micronations have serial numbers on their banknotes, such as Aelite, Hutt River, etc. Some micronations have a similar combination of numbers on their banknotes, which remains nonetheless identical on every single piece of the same banknote type - This should not be regarded as a valid serial number.
Signature: Handwritten signature is perhaps one of the easiest techniques for micronations to apply to their banknotes. In reality, it is indeed used by numerous micronations around the world, such as Avram in Australia, Rosginano in Italy, etc. In most cases, the signature belongs to their national leaders, whereas others also adopt the signature of the person responsible for the issuance of their banknotes.
