This high quality supply is commonly used in the tattoo studio. It has many different uses. Some of these include mixing inks together if they have thicker or thinner consistencies. They often will not blend well together so adding a little purified water can help mix the colours properly into an appropriate solution. Purified water is also used by many tattoo artists to dilute black ink to create differing shades when working on black and grey pieces. The water can create various different shades of grey and ink washes to create a semi-transparent effect within the tattoo design. Purified water is also heavily used by artists who are developing the new trend for water colour tattoos where there are not definitive edges and outlines. This involves the colour being blended seamlessly into the skin, which can be done much more easily when diluted with purified water to create a gradient of ink strengths. Purified water can also be used for aftercare solutions to help flush any excess ink and debris such as blood from the tattoo when it is completed. It is also helpful in changing the consistency of thicker pigments that are not always compatible with some tattoo machines which may only work with thinner inks.
