How much do you tip a tattoo artist?

As a general rule, tipping 10% is a MINIMUM, 15-20% is normal and anything more is considered tipping heavily. If you don't have the extra money to tip, at least explain that to your artist (they'll understand and appreciate it)- if you can, bring them a tip the next time you have a few extra dollars. Clients who are known to tip always get a little extra 'love' from their artist.
