Scores of young men and women are covering their body with beautiful tattoos everyday around you. Tattoo culture is now a respectable art and supports a healthy business around the world. Earlier, tattoos were associated with bikers and wandering artists. Variety of styles and designs available today is as wide as customers who love to put them on their skin. You can have a beautiful tattoo in almost any shade you like.
A tattoo artist creates a tattoo by injecting colorful pigment into customer's skin. The pigment is injected by pricking thousands of holes with the help of a needle. Nowadays, tattoo artists use electrical machines to puncture holes. A machine is capable of puncturing up to three thousand holes per minute by moving a solid needle to and fro. This needle and other materials such as hand gloves, bands are used only once in tattooing practices.
Samuel O'Reilly invented the tattoo machine in eighteenth century. This invention paced up the tattoo culture and brought down the associated costs. The basic operation of machine has not changed much in so many years. Needle used in a tattoo machine is sterilized and ink is pulled up with the help of a tube system. Tattoo artists follow universal precautions to prevent the transmission of contagious diseases and possibility of any kind of infection.
You might be wandering why the tattoo ink does not wash away. The beautiful tattoo that you see on the wrist of your friend is actually drawn on the second layer of the skin. You see the tattoo through the first layer of the skin. Dermis or second layer of the skin is considered to be a better candidate to place ink pigment because it has stable cells. Dermis allows the ink pigment to stay in place for a lifetime. Humans lose epidermis or first layer of skin very frequently. A tattoo drawn on the first layer of the skin will be gone in days.
