Question 1

What does the term 'needle gauge' refer to in tattooing?

Accepted Answer

The diameter (thickness) of the needle wire

Answer

Needle gauge refers to the diameter of the individual needle wire — a lower gauge number means a thicker wire, and higher gauge means thinner.

Question 2

In tattoo machine setup, what is the purpose of adjusting the 'give' or 'spring tension'?

Accepted Answer

It controls how far the needle travels and the softness of impact on the skin

Answer

Spring tension on a coil machine determines the needle throw distance and how hard the armature bar strikes, affecting needle penetration depth and machine feel.

Question 3

What is 'needle grouping' in tattoo needles?

Accepted Answer

The arrangement and number of individual needle pins soldered together on a bar

Answer

Needle grouping describes how multiple individual pins are soldered together — e.g., a 7-round shader (7RS) has 7 pins arranged in a circular pattern.

Question 4

Which surface disinfectant is commonly used between clients to clean tattoo workstation surfaces?

Accepted Answer

EPA-registered hospital-grade disinfectant (e.g., quaternary ammonium or bleach solution)

EPA-registered hospital-grade disinfectants are required for surface disinfection between clients to kill bloodborne pathogens on workstations, chairs, and equipment.

Question 5

What is the function of petroleum jelly (Vaseline) applied to the skin during tattooing?

Accepted Answer

It reduces friction, keeps the skin lubricated, and helps needles glide smoothly

A thin layer of petroleum jelly lubricates the skin surface during tattooing, reducing friction and helping the needle and tube glide smoothly without excessive skin trauma.
