Can you use sepia ink instead of Indian ink for tattoo's?

You should not use Indian ink or sepia ink or any other form of drawing ink for a tattoo. Tattoo pigments are made to be used for just that, tattooing. Any reputable tattooist will use QUALITY ink for a tattoo. If you're tattooing at home, take apart your machines, put them in a plastic Ziploc bag and go get an apprenticeship and stop spreading disease.
