Tattoo artists design and create permanent works of art on human skin.

Tattoo artists talk with customers about the design they want. Artists usually have a collection of designs displayed for customers to select from. They may also help a customer create a custom design.

Before starting a tattoo, artists discuss general health issues with customers such as skin or blood disorders, allergies, or diabetes. The artist also talks to customers about how the tattoo machine works and what it will feel like as the tattoo is made.

Before starting a tattoo, artists fill the ink dispensers with the colors of ink specified by customers. They insert new needles into the machine each time it is used. There are two types of machines, liners and shaders. Artists use liners to outline designs and shaders to fill in shapes with color.

When the tattoo is finished artists provide customers information about how to care for tattoos as they heal. They discard all materials such as gloves, dressings, and dyes used in each session. They use a machine called an autoclave to sterilize the needles.

Permanent color technicians also tattoo skin, usually for cosmetic purposes. For example, they may tattoo around a client's eyes to create eyeliner. Some technicians work with clients who have had skin traumas or surgery in order to make scars less noticeable.
