A needle can move from 50-3000 times every minute. The rate actually depends on the tattoo maker's preferences and needs. As an artist, you can fix the needle for slower or faster work. You have to consider different facts like the intricacy of the tattoos, the tattoo receiver’s skin, etc. Remember that the fleshy part of the body needs more ink. Hence, the speed should be fast. As the mature skin is more gentle, you have to use the needle at a slow pace.
