Bob Tyrrell Advanced Black and Grey Tattoo Ink Formula Set 4oz bottle

I'll line up 6 cups together, and put 1 cup a little away from the other 6 cups. The cup that's moved away is for Dimension Black. The next cup is for Sculpting Black, followed by Dark Tone, Medium Tone, Light Tone, and 2 cups of straight distilled water. The small cup for White I put behind the black set-up. Confused yet? Haha! I only use the Dimension Black for any solid black that I'm doing in the tattoo, whether it be a portrait, custom demon or whatever.
When I want to blend into some shade of gray from the solid black, I switch to Sculpting Black, blending that out from the Dimension Black. From there you can start with the grays. Keep in mind there's no right or wrong way of doing things, and there's no magic technique for black and gray work. Everyone's technique is a little different, but we all try to achieve the same results, which is rich, smooth black and gray!
When I'm working, I don't just dip into one cup at a time. Sometimes I do, and sometimes I dip into two cups at the same time to get a different value. Using water is very important, and you can buy a separate empty bottle from INTENZE if you want it to match the rest of the set. Just re-fill it with straight distilled water.
The other way I use the ink, because I like to keep things simple, is to use the large plastic ink cups and set out 4 cups. 3 together, and 1 moved away a little which is for Dimension Black. The next 3 cups will be Sculpting Black, Medium Tone, and distilled water. I'm eliminating Dark Tone and Light Tone. I can achieve the same results, it's all in the way you dip. For less advanced artists, I'd get used to the first method first. If you want to try the second method when you get comfortable, it's up to you. If you like the first method, you can stick with that. I have friends who are some of the best black and gray artists in the world, and some use a lot of cups, while some just use a cup of black and a cup of water.
