Complete guide: Intenze Gen Z Black Sumi 30ml
Black Sumi is the black ink from Intenze's Gen Z collection, specifically designed for controlled dilution — from an intense, dense black to fine gray tones. It is useful for artists who work with washes, shadows, and transitions, not just outlines: realism, portraits, or traditional Japanese style, where gray gradients make the difference between a flat background and one with depth. The formula complies with European REACH regulations, is vegan, not tested on animals, manufactured in the USA, and verified in CTL Bielefeld laboratories. Tatuat.ro is an authorized Intenze distributor in Romania, so you have the guarantee of an original 30 ml bottle.
How to use
- Check the bottle upon receipt — the seal and label must be intact; the product comes sterile packaged from the factory.
- Gently homogenize the contents before pouring, so the pigments remain evenly distributed.
- Pour only the amount you need into disposable cups (cap cups); do not work directly from the bottle to avoid contaminating the remaining ink.
- For lines and dense black areas, use the ink undiluted, at full concentration.
- For washes and gray tones, dilute with distilled water in a separate cup — roughly 1:1 for dark gray, 1:2–1:3 for medium tones, and 1:5 or more for very light washes.
- Mix each dilution well and test the tone on a sketch or test surface before working on the final area on the skin.
- Work with needles and configurations suitable for the chosen technique (liner for outline, magnum/shader for wash), following the usual hygiene protocol of the session.
- At the end, close the bottle cap tightly and store it properly; used cups are discarded, not reused for another client.
Tips from us
- If you need multiple gray tones in the same session, prepare the dilutions in advance, in separate and labeled cups with the ratio used, so you can reproduce the exact same tone later.
- Dilute with distilled water, not tap water — it maintains the formula's stability and reduces the risk of contamination.
- Test any new dilution on paper or a small area before applying it extensively, especially if you are experimenting with a ratio you haven't used before.
- Black Sumi also works at full concentration for dense black, but it is formulated specifically for dilution — if you work almost exclusively with fine outlines, also consider a dedicated lining ink.
- Keep the bottle in a dry place, away from direct light and extreme temperatures, with the cap tightly closed, to maintain its consistency and fluidity over time.
- Being a vegan and REACH/ECHA compliant formula, it is a suitable choice if you want to meet the composition requirements valid in the EU at the studio level.
Warning: The ink is applied to perforated skin, so the studio's standard hygiene protocol must be followed: gloves, disposable barriers on equipment, sterile disposable needles and cups per client, disinfection of work surfaces. Ink poured into a cup must never be reintroduced into the bottle and must not be reused for another client. Ask the client about any known allergies or sensitivities before the session. This guide does not replace your studio's hygiene protocols and does not constitute medical advice.
Frequently asked questions
What is "sumi" ink and how is it different from a regular black lining ink?▾
The term "sumi" comes from the Japanese tradition of calligraphy ink and refers to a black specifically designed for controlled dilution. Unlike a standard black, optimized for dense, opaque outlines, Black Sumi dilutes smoothly and evenly, producing clear, nuanced shades of gray — although it can also be used undiluted for intense black.
How do I properly dilute Black Sumi for a wash or gray gradient?▾
It is diluted with distilled water, depending on the desired tone: roughly 1:1 (ink:water) for a dark gray, 1:2 or 1:3 for medium tones, and 1:5 or more for very light washes. Mix each dilution well and test it on a test surface before application — each artist, with experience, arrives at their own preferred ratios.
Is it more suitable for washes or can it also be used for lining?▾
It is formulated specifically for washes, gradients, and controlled dilution, but can also be used at full concentration for a dense black. If your work is almost exclusively fine lining, a dedicated lining ink may be more suitable; for realism, portraits, or traditional Japanese style, where you need gray transitions, Black Sumi shows its advantage.
How do I store the ink to maintain its quality between sessions?▾
Keep the bottle in a dry place, away from direct light and extreme temperatures, with the cap tightly closed. Always pour the necessary amount into disposable cups and never pour leftover ink back into the bottle — this protects the rest of the product from contamination.
Is it suitable for traditional Japanese style and realism/portraits?▾
Yes — the dilution properties of Black Sumi allow the subtle gray gradients specific to both styles: background fills, waves, smoke, and clouds in Japanese style, respectively shadows and fine transitions in realism and portraits.
What safety and compliance guarantees does this ink have?▾
It complies with European REACH and ECHA regulations, vegan formula, not tested on animals, manufactured in the USA and tested in CTL Bielefeld laboratories. It comes sterile packaged, and tatuat.ro is an authorized Intenze distributor in Romania, with authenticity guarantee.

Frequently Asked Questions What is sumi ink and why is it special? Sumi ink is inspired by the Japanese tradition of ink used in calligraphy and rice paper art. In tattooing, the term sumi refers to a black with special dilution properties allowing creation of subtle, nuanced gray tones. Intenze's Black Sumi brings this versatility to the modern professional tattoo ink format. What is the difference between Black Sumi and a standard lining black? Black Sumi is specially formulated for washes, gradations, and controlled dilution, while a standard lining black is optimized for dense, opaque outlines. Black Sumi dilutes more smoothly and uniformly, producing clearer, more nuanced gray tones. It can be used at full concentration too, but reaches its maximum potential in wash techniques. How should Black Sumi be correctly diluted for washes? Black Sumi is diluted with distilled water in varied proportions depending on the desired gray tone. For dark gray, use a 1:1 ink-to-water ratio. For medium tones, 1:2 or 1:3. For very light washes, 1:5 or more. Mix well and test on a surface before application. Each artist develops their preferred proportions through experience. Is Black Sumi suitable for traditional Japanese style? Yes, Black Sumi is ideal for traditional Japanese style due to its dilution properties allowing creation of the subtle gray gradations characteristic of this style. Background fills, water waves, smoke, and clouds are classic Japanese style elements that greatly benefit from Black Sumi's versatility in producing varied tones. Does Black Sumi work well for realism and portraits? Absolutely, Black Sumi is excellent for realism and portraits due to its ability to produce a wide range of controllable gray tones. Realistic artists need fine transitions and subtle gradations that Black Sumi offers naturally. From deep shadows to delicate highlights, this ink covers the entire tonal spectrum needed. How does Black Sumi behave after healing? After complete healing, Black Sumi retains its intensity at maximum concentration and the clarity of gray tones in diluted versions. Long-term chromatic stability is ensured by premium quality Intenze pigments. Like any tattoo ink, slight attenuation is normal, but gradations and transitions retain their clarity and nuances. Can Black Sumi be used for outlines? Yes, at maximum concentration, Black Sumi delivers an intense black suitable for outlines. However, if seeking a black dedicated exclusively to dense lining, Intenze offers other formulas specifically optimized for outlines. Black Sumi reaches its maximum versatility when used for gradations, washes, and shading techniques. Is Black Sumi compatible with all tattoo machines? Yes, Intenze Gen Z Black Sumi is compatible with all tattoo machine types: coil, rotary, and pen. The fluid consistency ensures excellent flow through any needle configuration. It is particularly performant with magnum and curved magnum configurations frequently used for shading and washes in the styles where Black Sumi excels. Is Black Sumi vegan and cruelty-free? Yes, Intenze is a brand dedicated to vegan and cruelty-free products. Black Sumi, like the entire Gen Z range, contains no animal-derived ingredients and is not tested on animals. This ethical positioning is consistently maintained across the entire Intenze range, reflecting the company's values and the modern tattoo artist community's values.
