Tattoos use the principle of capillaries to immerse two or more tightly bound needles into a liquid. Due to the thin tube phenomenon between needles, the raw material is kept between several needles. Therefore, the needle is used to pierce the skin and the pigment is injected into the skin.
The potion is black before being injected into the skin, but after being injected into the skin, due to the influence of melanin, it will become blue after a period of time, so the descendants call it tattoos. It is often said that there is a tattoo method that will emerge after drinking, stabbed with pigeon blood and cinnabar. But in terms of physiological health, due to avian flu and other avian diseases, current tattooists do not use this method of tattooing.
The tattoo machine is powered by electricity. After being driven by electricity, a number of parallel needles in the needle tube will jump up and down. Due to the high frequency of beating, the operation time is greatly shortened. In recent years, with the advancement of technology, this electric tattoo machine has been improved. Among them, the number of needles has increased, and the power has also been improved. Of course, the tattoo time is shorter, and the pain is shortened.
