Let me guess...you have a bottle of black ink and you want to do a red tattoo. The ONLY way you can do a red tattoo is to use red ink. No amount of dilution will make black ink red.
Tattoo ink would separate because it is water based so that it doesn't harm the body.
For the most part, when you are wanting to dilute the ink you will use small amounts of Witch Hazel to water it down. You can also use distilled water. In the event of you doing soft gray shading, you will want to use the witch hazel to dilute the black. The witch hazel will reduce the redness of the tattooing while you are doing it, and will allow you to see more clearly the black that you are building up in the skin.
Yes
No, tattoo ink isn't flammable.
Absolutely not. Tattoos should only be done with quality tattoo ink. Furthermore, tattoo ink needs to be pigmented, fade-proof, water-proof, & non-toxic. Tattoos are too permenant to be done in anything other than real, quality tattoo ink. Better ink tends to get a little expensive, but the trouble it saves makes it worth it. Mutt
No, tattoo ink does not typically contain iodine. Tattoo ink is made up of pigments and carriers that are specifically designed for use in the skin. Iodine is not a common ingredient in tattoo ink.
No.
Yes, mixing tattoo ink is done every day in the tattoo studio. It works pretty much just the same as mixing any other kinds of ink.
only if you use blood red
MOM'S Ink, Skin Candy, Intenze, and Kuri Sumi. These are the only tattoo inks I trust and are most popular. Use the wrong tattoo ink and you'll get a crappy faded tattoo.
