Distilled water can be very useful within the tattoo industry. It is ideal for rejuvenating the dried out or thicker inks, as many of these are not compatible with different tattoo machines and needle set ups. Some more modern tattoo machines are better used with more fluid inks, whereas some more traditional set ups are ideal with the thicker, highly pigmented old style of ink production. By adding small amounts of distilled water to these inks, they are then suitable for use. By having a more fluid consistency, the ink is able to flow through the tubes and machine more easily, as well as being easier to work into the skin's surface. The professional instrument water technique of diluting tattoo ink can be very useful when producing the varying of shades of black and grey. By adding small amounts of distilled water to the mixture of inks, it can increase the fluidity of the ink shades and make them easier to apply into the skin's surface. Using distilled water to rinse off debris and cleaning the tattoo while it is in progress can also be a better solution than using regular water which is not sterile in the same way that distilled water is.
