Tattoo

A tattoo is a form of body modification, made by inserting indelible ink into the dermis layer of the skin to change the pigment. The first written reference to the word, "tattoo" (or Samoan "Tatau") appears in the journal of Joseph Banks, the naturalist aboard Captain Cook's ship the HMS Endeavour: "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humor or disposition". Tattooing has been practiced for centuries in many cultures spread throughout the world, particularly those found in Asia. The Ainu, an indigenous people of Japan, traditionally had facial tattoos. Today, one can find Berbers of Tamazgha (North Africa), Māori of New Zealand, Hausa people of Northern Nigeria, Kurdish people in East-Turkey and Atayal of Taiwan with facial tattoos. Tattooing was widespread among Polynesians and among certain tribal groups in Taiwan, Philippines, Borneo, Mentawai Islands, Africa, North America, South America, Mesoamerica, Europe, Japan,Cambodia, New Zealand and Micronesia. Indeed, the island of Great Britain takes its name from tattooing, with Britons translating as 'people of the designs' and the Picts, who originally inhabited the northern part of Britain, which literally means 'the painted people. Despite some taboos surrounding tattooing, the art continues to be popular in many parts of the world.

Procedure

Traditional Hawaiian hand-tapped tattoos are experiencing a renaissance, after the practice was nearly extinguished in the years following Western contact. The process involves lengthy protocols and prayers and is considered a sacred rite more than an application of artwork. The tattooist chooses the design, rather than the wearer, based on genealogical information. Each design is symbolic of the wearer's personal responsibility and role in the community. Tools are hand-carved from bone or tusk without the use of metal.

Prices for this service vary widely globally and locally, depending on the complexity of the tattoo, the skill and expertise of the artist, the attitude of the customer, the costs of running a business, the economics of supply and demand, etc. The time it takes to get a tattoo is in proportion with its size and complexity. A small one of simple design might take 15 minutes, whereas an elaborate sleeve tattoo or back piece requires multiple sessions that may consist of several hours at a time.The most common method of tattooing in modern times is the electric tattoo machine, which inserts ink into the skin via a single needle or a group of needles that are soldered onto a bar, which is attached to an oscillating unit. The unit rapidly and repeatedly drives the needles in and out of the skin, usually 80 to 150 times a second. This modern procedure is ordinarily sanitary. The needles are single-use needles that come packaged individually. The tattoo artist must wash his or her hands and must also wash the area that will be tattooed. Gloves must be worn at all times and the wound must be wiped frequently with a wet disposable towel of some kind. The equipment must be sterilized in a certified autoclave before and after every use.

In 1891 the first electric tattoo needle was invented in New York City by modifying Thomas Edison's electric engraving pen. This made the process cheaper and faster; it was taken up by the poor and abandoned by the rich. O'Reilly's machine was based on the rotary technology of the electricengraving device invented by Thomas Edison. Modern tattoo machines use electromagnetic coils. The first coil machine was patented by Thomas Riley in London in 1891, using a single coil. The first twin-coil machine, the predecessor of the modern configuration, was invented by another Englishman, Alfred Charles South of London, in 1899.

Another tattoo machine was developed 1970-1978 by the German tattoo artists Horst Heinrich Streckenbach (1929–2001) and Manfred Kohrs.

Dyes and pigments

Early tattoo inks were obtained directly from nature and were extremely limited in pigment variety. In ancient Hawaii, for example, kukui nut ash was blended with coconut oil to produce an ebony ink. Today, an almost unlimited number of colors and shades of tattoo ink are mass-produced and sold to parlors worldwide. Tattoo artists commonly mix these inks to create their own unique pigments.

Modern tattooing inks are carbon-based pigments that have uses outside of commercial tattoo applications. In 2005 at Northern Arizona University a study characterized the makeup of tattoo inks (Finley-Jones and Wagner). The FDA expects local authorities to legislate and test tattoo pigments and inks made for the use of permanent cosmetics. In California, the state prohibits certain ingredients, and prosecutes companies who fail to notify the consumer of the contents of tattoo pigments.A wide range of dyes and pigments can be used in tattoos, from inorganic materials like titanium dioxide and iron oxides to carbon black, azo dyes, andacridine, quinoline, phthalocyanine and naphthol derivatives, dyes made from ash, and other mixtures. Iron oxide pigments are used in greater extent incosmetic tattooing.

Concern has been expressed over the interaction between magnetic resonance imaging (MRI) procedures and tattoo pigments, some of which containtrace metals. The magnetic fields produced by MRI machines interact with these metals, including nonferrous metal particles, and while rare, are capable of causing first-degree or second-degree burns or distortions in the image. The type and density of the ink as well as shape of the tattoo may increase the risk, particularly if the shape approximates an RF pick-up loop. The television show MythBusters tested the hypothesis, and found a slight interaction between commonly used tattoo inks and MRI. The interaction was stronger with inks containing high levels of iron oxide.

Studio hygiene

The properly equipped tattoo studio will use biohazard containers for objects that have come into contact with blood or bodily fluids, sharps containers for old needles, and an autoclave for sterilizing tools. Certain jurisdictions also require studios by law to have a sink in the work area supplied with both hot and cold water.

Proper hygiene requires a body modification artist to wash his or her hands before starting to prepare a client for the stencil, between clients, and at any other time where cross contamination can occur. The use of single use disposable gloves is also mandatory. Also, disposable gloves should be taken off after each stage of tattooing. The same gloves should not be used to clean the tattoo station, tattoo the client, or clean the tattoo; the tattoo artist should change their disposable gloves at each stage. In some states and countries it is illegal to tattoo a minor even with parental consent, and (except in the case of medical tattoos) it is forbidden to tattoo impaired persons, people with contraindicated skin conditions, those who are pregnant or nursing, those incapable of consent due to mental incapacity or those under the influence of alcohol or drugs.

Before the tattooing begins the client is asked to approve the final position of the applied stencil. After approval is given the artist will open new, sterile needle packages in front of the client, and always use new, sterile or sterile disposable instruments and supplies, and fresh ink for each session (loaded into disposable ink caps which are discarded after each client). Also, all areas which may be touched with contaminated gloves will be wrapped in clear plastic to prevent cross-contamination. Equipment that cannot be autoclaved (such as counter tops, machines, and furniture) will be wiped with an approved disinfectant.

Membership in professional organizations, or certificates of appreciation/achievement, generally helps artists to be aware of the latest trends. However, many of the most notable tattooists do not belong to any association. While specific requirements to become a tattooist vary between jurisdictions, many mandate only formal training in blood borne pathogens, and cross contamination. The local department of health regulates tattoo studios in many jurisdictions.

For example, according to the health departments in Oregon and Hawaii, tattoo artists in these states are required to take and pass a test ascertaining their knowledge of health and safety precautions, as well as the current state regulations. Performing a tattoo in Oregon without a proper and current license or in an unlicensed facility is a felony offense. Tattooing was legalized in New York City in 1997, and in Massachusetts and Oklahoma between 2002 and 2006.

Aftercare

Tattoo specific salves have become prevalent in recent years.

Tattoo artists, and people with tattoos, vary widely in their preferred methods of caring for new tattoos. Some artists recommend keeping a new tattoo wrapped for the first 24 hours, while others suggest removing temporary bandaging after two hours or less to allow the skin to 'breathe'. Many tattooists advise against allowing too much contact with hot tub or pool water, or soaking in a tub for the first two weeks. This is to prevent the tattoo ink from washing out or fading due to over-hydration and to avoid infection from exposure to bacteria. In contrast, other artists suggest that a new tattoo be bathed in very hot water early.

General consensus for care advises against removing the scab that may form on a new tattoo, and avoiding exposing one's tattoo to the sun for extended periods for at least 3 weeks; both of these can contribute to fading of the image. It is agreed that a new tattoo needs to be kept clean. Various products may be recommended for application to the skin, ranging from those intended for the treatment of cuts, burns and scrapes, to cocoa butter,hemp, salves, lanolin, A&D, Bepanthen or Aquaphor. Oil based ointments are almost always recommended to be used in very thin layers due to their inability to evaporate and therefore over-hydrate the already perforated skin. In recent years, specific commercial products have been developed for tattoo aftercare. Although opinions about these products vary, there is near total agreement that either alone or in addition to some other product, soap and warm water work well to keep a tattoo clean and free from infection. Ultimately, the amount of ink that remains in the skin throughout the healing process determines, in large part, how robust the final tattoo will look. If a tattoo becomes infected (uncommon but possible if one neglects to properly clean their tattoo) or if the scab falls off too soon (e.g. if it absorbs too much water and sloughs off early or is picked or scraped off), then the ink will not be properly fixed in the skin and the final image will be negatively affected.
