PROCEDURE

Modern tattoo machine in use (see below) are outfitted with a 5-needle setup, but number of needles depends on size and shading desired. Some tribal cultures still create tattoos by cutting designs into the skin and rubbing the resulting wound with ink, ashes or other agents. This may be an adjunct to scarification. Some cultures create tattooed marks by "tapping" the ink into the skin using sharpened sticks or animal bones. Traditional Japanese tattoos (irezumi) are still "hand-poked," that is, the ink is inserted beneath the skin using non-electrical, hand-made and hand held tools with needles of sharpened bamboo or steel. The most common method of tattooing in modern times is the electric tattoo machine. Ink is inserted into the skin via 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 50 to 3,000 times a minute.
