Abstract- A tattoo is a form of body modification where a design is made by inserting ink, dyes and pigments, either indelible or temporary, into the dermis layer of the skin to change the pigment. The art of making tattoos is tattooing. Tattoos fall into three broad categories: purely decorative; symbolic; pictorial.
A tattooist today works with electrical application devices based either on a spooling or a rotational principle. Both methods are employed, but rotational systems are gaining increasing favour due to their simpler. With frequencies between 70 and 170 Hz and a penetration depth of up to 4 mm, needles previously dipped in colouring matter are driven into the skin by the device.
