Complete guide: Intenze drawing ink Formula 23 Greywash Medium 300ml
Intenze Formula 23 Greywash Medium is the intermediate gray tone from a pre-mixed system with three tones — Light, Medium and Dark — from the Formula 23 line created by Mario Barth. The medium tone is the one used for most shading and for smooth transitions from light to dark in black and grey work. The 300 ml bottle gives you a consistent supply, and the pre-mixed formula gives you the same tone from one session to the next. On tatuat.ro the product is listed in the 'drawing ink' category.
How to use
- Shake the bottle well before each use so that the pigment is evenly redistributed throughout the liquid.
- Pour only the amount you need into a disposable ink cap; never work directly from the bottle.
- Build the tones progressively: start with Light for light areas, switch to Medium for intermediate tones and transitions, then Dark for the deepest shadows.
- Use Medium for the bulk of shading — it acts as the 'bridge' between light and dark and gives volume to the work.
- Never return leftover ink from the ink cap back into the bottle to avoid contaminating the supply.
- Finally, wipe the bottle mouth, close it tightly, and store it away from direct light and heat sources.
Tips from us
- Keep all three tones from the same line (Light, Medium, Dark) for uniform transitions — they have the same formula base and working consistency.
- As the most rapidly consumed tone, the 300 ml format helps you avoid running out of Medium in the middle of a job.
- The same shade covers both large areas with magnum configurations and intermediate details with round shaders.
- Note the opening date on the bottle and rotate stock using the 'first opened, first used' rule.
- Upon receipt, check that the bottle is sealed and do not use it if the packaging is damaged.
Warning: On the product page, this ink is listed as drawing ink, not for tattooing; according to the note in the description, use for any purpose other than that stated is the consumer's responsibility. Regardless of use, follow hygiene rules: use disposable ink caps, do not pour leftover ink back into the bottle, shake before use, and keep the bottle tightly closed, away from light and heat. From the available data, I cannot confirm the exact composition, expiration date, or compliance with European regulations — check the label and official product sheet.
Frequently asked questions
Why is the Medium shade the most used of the three?▾
Medium covers most of the surface in black and grey work. Light is used only for light areas, Dark only for deep shadows, and Medium is the main shading tone that completes transitions and volume. That is why it is consumed the fastest, and the 300 ml bottle is designed exactly for this pace of work.
How do I choose between Light, Medium and Dark?▾
The three are used together, layered: Light for highlights, Medium for intermediate tones and transitions, Dark for the deepest shadows. If you're getting a single shade for general shading, Medium is the basic choice. For complete depth, it's ideal to have all three, because they have the same formula base and blend without adjustments.
How do I properly maintain the bottle to make it last?▾
Shake it well before each use, pour only into disposable ink caps, and never pour leftover ink back. Wipe the bottle mouth, close it tightly, and keep it away from direct light and heat sources. Note the opening date and consume stock in the order you opened the bottles.
What is the advantage of it being pre-mixed?▾
The pre-mixed formula gives you a consistently calibrated medium gray tone without having to manually mix black with diluent. This way you get the same shade from one session to the next, eliminating variations and making your work easier, especially on large surfaces where uniformity matters.
Is the 300 ml format worth it or is it too much?▾
It depends on your workload. Being the most rapidly consumed shade, 300 ml is a practical size for someone who does a lot of shading and doesn't want to order often. If you work occasionally, a smaller size might be enough for you — check if the range is also available in other sizes.

Formula 23 Greywash Medium heals with stable, uniform tonality, maintaining the original tonal balance without unwanted chromatic shifts.

Its compatibility with all tattoo machine types makes it a universal choice for professionals.
Frequently Asked Questions Why is Greywash Medium the most consumed ink in the range? Greywash Medium is the most consumed because it covers the largest area in black and grey work. While Light is only used for highlights and Dark only for deep shadows, Medium represents the primary shading tone that fills the majority of volumetrics and transitions in portraits, realism, and illustrations. How are the three greywash tones used together? The three tones are layered progressively. Start with Light for highlights and the brightest areas, continue with Medium for intermediate tones and transitions, and apply Dark for deep shadows and the darkest areas. This layering creates depth and dimensionality, transforming a flat design into a three-dimensional piece. Is Formula 23 Medium suitable for cover-ups? Formula 23 Greywash Medium can be used in cover-ups as a transition tone but lacks the opacity needed to completely cover an old tattoo. For effective cover-ups, Dark or Formula 23 Original black are more suitable for base layers. Medium excels in finishing and adding intermediate details over areas already covered with darker tones. How does Medium's consistency compare to Light and Dark? All three tones share the same formula base and the same working consistency, differing only in pigment concentration. Medium flows as fluidly as Light and Dark through all needle types. This consistency uniformity is one of the major advantages of the Formula 23 range, enabling seamless transitions between tones without setting adjustments. Can I use Greywash Medium for geometric tattoos? Yes, Greywash Medium is excellent for geometric tattoos requiring uniform areas of medium grey. Its predictable consistency allows even filling of geometric shapes without tonal variation. It is popular in geometric dotwork, mandala, and ornamental styles, where uniform grey tonality is essential to the design's aesthetics. How quickly does the ink dry on skin during work? Formula 23 Greywash Medium has an optimized drying time that allows the artist to work comfortably without the ink drying too quickly on skin or in the ink cap. The formula maintains fluidity throughout the entire session, even in long 4-6 hour sessions. This stability reduces waste and ensures consistent application quality. Is Formula 23 Medium compliant with European regulations? Intenze Products manufactures inks that meet international safety and quality standards. For the European market, it is important to verify the specific batch labeling in relation to applicable REACH and Res AP regulations. Tatuat.ro only sells products compliant with applicable legislation on the Romanian market. Can I combine Formula 23 Medium with colored inks? Yes, Formula 23 Greywash Medium can be mixed with colored inks to create desaturated versions or pastel tones of colors. This technique is popular in color realism, where pure colors are rarely used without being modulated with grey tones. Mixing with Medium creates more natural and realistic tones. Can Greywash Medium be used for scalp tattoos? Yes, Formula 23 Greywash Medium is a popular choice for scalp micropigmentation (SMP). Its medium grey tonality replicates the appearance of shaved hair follicles, creating the illusion of hair density. For SMP, it is recommended to use fine needles and specific stippling techniques adapted to the unique texture of scalp skin. What happens if the ink thickens in the ink cap during the session? During long sessions, the ink may begin to slightly thicken due to evaporation. In this case, add a few drops of Intenze Mixing Solution or Distilled Mixer to restore optimal consistency. Do not use tap water for dilution as it can introduce bacteria and impurities. Replace the ink in the cap if the session exceeds 2-3 hours.
