 can occur. The use of single use disposable gloves is also mandatory. In some states and countries it is illegal to tattoo a minor even with parental consent, and it is usually not allowed to tattoo impaired persons, people with contraindicated skin conditions, those who are pregnant or nursing, or those incapable of consent due to mental incapacity. Before the tattooing begins the client is asked to approve the position of the applied stencil. After approval is given the artist will open new, sterile needle packages in front of the client, and always use new, sterile or sterile disposable instruments and supplies, and fresh ink for each session (loaded into disposable ink caps which are discarded after each client). Also, all areas which may be touched with contaminated gloves will be wrapped in clear plastic to prevent cross-contamination. Equipment that cannot be autoclaved (such as countertops, machines, and furniture) will be wiped with an approved disinfectant.

Membership in professional organizations, or certificates of appreciation/achievement, generally helps artists to be aware of the latest trends. However, many of the most notable tattooists do not belong to any association. While specific requirements to become a tattooist vary between jurisdictions, many mandate only formal training in bloodborne pathogens, and cross contamination. The local department of health regulates tattoo studios in many jurisdictions.

For example, according to the health department in Oregon and Hawaii, tattoo artists in these states are required to take and pass a test ascertaining their knowledge of health and safety precautions, as well as the current state regulations. Performing a tattoo in Oregon state without a proper and current license or in an unlicensed facility is considered a felony offense. Tattooing was legalized in New York City, Massachusetts, and Oklahoma between 2002 and 2006.

Tattooers may use flash (pre-drawn, stock images that can be traced onto the skin) or create original tattoos for their customers.
