La ce se folosesc cartușele Flat și prin ce diferă de liner sau magnum?

Configurația Flat (F) așază acele pe un singur rând drept, așa că lasă o linie groasă și uniformă dintr-o singură trecere — exact ce ai nevoie la tribal, geometric, lettering bold, Polynesian sau blackwork cu margini definite. Un liner (RL) grupează acele în cerc pentru contururi subțiri, iar un magnum are rânduri suprapuse pentru umbre și umpleri moi. Flat-ul e la mijloc: mai lat decât un liner, dar cu margine mult mai fermă decât un magnum.

Ce diferență este între gauge #10 și #12 și pe care îl aleg?

Kwadron F este disponibil în gauge #10 (0,30 mm) și #12 (0,35 mm). #10 produce linii groase cu traumă mai mică asupra pielii — potrivit pentru zone sensibile sau piele subțire, de exemplu la lucrări Polynesian cu margini mai delicate. #12 penetrează mai ferm și este alegerea clasică pentru piele groasă și tribal bold. Diferența de gauge influențează lățimea efectivă a liniei, penetrarea și vindecarea, deci merită să ai ambele variante în studio.

Sunt compatibile cu mașina mea?

Cartușele Kwadron au compatibilitate universală cu mașinile pen-style care acceptă cartușe standard. Pentru dimensiunile mari de flat (11F și peste) sunt recomandate mașinile cu motor puternic; mașinile entry-level le pot folosi, dar uneori cer voltaje mai mari ca să mențină lovitura constantă pe toată lățimea rândului de ace.

Ce dimensiuni există și cum aleg între ele?

Gama Kwadron F acoperă 5F, 7F, 9F, 11F, 13F și 15F, fiecare disponibilă în gauge #10 și #12. Ca reper: 5F pentru lettering fin și detalii, 7F și 9F pentru pattern-uri standard (cele mai folosite), 11F pentru linii dominante, iar 13F–15F pentru blackwork masiv. Dacă abia treci pe flat-uri, 7F sau 9F sunt un punct de start echilibrat.

La ce voltaj lucrez cu Kwadron F?

Orientativ: gauge #12 la 7,5–9V, gauge #10 la 7–8,5V. Pentru linii singulare rămâi în zona 7,5–8,5V, iar pentru umpleri rapide urci spre 8–9V. Membrana permite un flux constant de cerneală fără să fie nevoie de supravoltare, iar unghiul de circa 90° față de piele ajută la o depunere uniformă. Valorile sunt punct de plecare — ajustează după mașina ta și după reacția pielii.

Pot refolosi un cartuș la același client, la o ședință viitoare?

Nu. Cartușele sunt ambalate individual, sterilizate EO și concepute strict pentru unică folosință — chiar și la același client, un cartuș folosit este deșeu contaminat și se aruncă în containerul pentru obiecte înțepătoare-tăietoare imediat după ședință. Nu există metodă sigură de curățare sau resterilizare în studio pentru un cartuș cu membrană; refolosirea creează risc real de infecție și încalcă normele de igienă.

Guide & full description

Complete guide: TATTOO NEEDLES CARTRIDGE KWADRON F

Kwadron Flat (F) configuration cartidges have the needles arranged in a single straight row, allowing them to lay down thick, uniform lines in a single pass. They are manufactured in Poland from stainless steel, with a medical-grade plastic housing that reduces friction between the needle and the housing, plus a safety membrane for controlled ink flow. They are intended for artists working with tribal, geometric, bold lettering, Polynesian or blackwork, as well as those wanting a consistent flat for fills with defined edges. Being sterile and single-use, they mount directly onto pen-style machines compatible with cartidges.

How to use

Check the individual packaging before opening: if the blister pack is damaged or unsealed, do not use the cartidge — sterility is no longer guaranteed.
Sanitize your hands, put on disposable gloves, and prepare the station with protective barriers (plastic wrap on the machine, clip cord sleeve, clean work area).
Remoive the cartidge from the blister without touching the tip and install it into the pen-style machine until it locks firmly in place.
Adjust the needle projection from the grip to the desired working depth and prime the tip with ink from the cap.
Set the voltage guidance according to gauge: approximately 7.5–9V for #12 (0.35 mm) and 7–8.5V for #10 (0.30 mm); for single lines stay in the 7.5–8.5V range, for quick fills go up to 8–9V — fine-tune according to your machine and style.
Work by holding the machine at an angle of approximately 90° to the skin, so that the entire row of needles deposits evenly across the entire width of the line.
Wipe away excess between passes and visually inspect the line — a correctly used flat leaves a homogenous band, without lighter areas on the edges.
At the end, remoive the cartidge with gloves and discard it in the sharps container. Do not reuse or re-sterilize.

Tips from us

Choose the size according to the line's role: 5F for details and fine lettering, 7F and 9F for standard patterns, 11F–15F for dominant lines and massive blackwork.
Use gauge #10 (0.30 mm) on sensitive areas or thin skin where you want a thick line with less trauma, and #12 (0.35 mm) on thick skin or bold tribal where you need firmer penetration.
For large flats (11F and above), a machine with a powerful motor keens the pace better; on entry-level machines you may need higher voltage.
The membrane prevents ink from flowing back towards the motor, but does not replace barriers: alwys wrap the machine and cable in protective film.
Combine F cartidges with liners (RL) for thin outlines — the flat lays the thick band, the liner does the detail, and together they cover a complete tribal or geometric project.
Store cartidges in their original packaging, in a dry, clean place, and open them only at the time of use.

Warning: Cartidges are EO sterilized and strictly single-use: a used cartidge, one that has been dropped on the floor or has a compromised blister pack must be discarded; do not clean or re-sterilize. Alwys work with gloves and protective barriers, and after the session discard the cartidges exclusively in a sharps container, in accordance with hygiene standards for tattoo studios. Tattooing must only be performed under professional hygiene conditions.

Frequently asked questions

What are Flat cartridges used for and how do they differ from liner or magnum?▾

The Flat (F) configuratioin places the needles in a single straight row, so it leaves a thick, uniform line in a single pass — exactly what you need for tribal, geometric, bold lettering, Polynesian or blackwork with defined edges. A liner (RL) groups needles in a circle for thin outlines, while a magnum has overlapping rows for shading and soft fills. The flat is in between: wider than a liner, but with a much firmer edge than a magnum.

What is the difference between gauge #10 and #12 and which one should I choose?▾

Kwadron F is available in gauge #10 (0.30 mm) and #12 (0.35 mm). #10 produces thick lines with less trauma to the skin — suitable for sensitive areas or thin skin, for example in Polynesian work with more delicate edges. #12 penetrates more firmly and is the classic choice for thick skin and bold tribal. The gauge difference affects effective line width, penetration and healing, so it's worth having both variants in the studio.

Are they compatible with my machine?▾

Kwadron cartidges have universal compatibility with pen-style machines that accept standard cartidges. For large flat sizes (11F and above), machines with a powerful motor are recommended; entry-level machines can use them but sometimes require higher voltage to maintain a consistent strike across the full width of the needle row.

What sizes are available and how do I choose between them?▾

The Kwadron F range covers 5F, 7F, 9F, 11F, 13F and 15F, each available in gauge #10 and #12. As a reference: 5F for fine lettering and details, 7F and 9F for standard patterns (most used), 11F for dominant lines, and 13F–15F for massive blackwork. If you are just switching to flats, 7F or 9F are a balanced starting point.

At what voltage do I work with Kwadron F?▾

As a guide: gauge #12 at 7.5–9V, gauge #10 at 7–8.5V. For single lines stay in the 7.5–8.5V range, and for quick fills go up to 8–9V. The membrane allows a constant ink flow without needing over-voltage, and an angle of about 90° to the skin helps uniform deposition. The values are a starting point — adjust according to your machine and the skin's reaction.

Can I reuse a cartidge on the same client at a future session?▾

No. The cartidges are individually packaged, EO sterilized and strictly single-use — even on the same client, a used cartidge is contaminated waste and is to be discarded into the sharps container immediately after the session. There is no safe method of cleaning or re-sterilizing in a studio for a membrane cartidge; reuse creates a real risk of infection and violates hygiene standards.
