Tattoo Needle Codes Decoded: Your Guide to RL, RS, RM,M1, and F1

What mysterious codes are Round Liner(RL),Round Shader(RS),Round Magnum(RM),Magnum(M1), and Flat(F1)?

Walking into the world of tattoo supplies can feel like deciphering a secret language. You see product names like "Gewinner RL 07" or "Magic Moon M1 09" and wonder, what do these tattoo needle codes actually mean? Understanding this needle configuration alphabet is crucial for every artist, from beginner to pro. It's the key to choosing the right tool for the job, ensuring precision, efficiency, and the perfect outcome for your client. This guide will break down the meaning behind these letters and numbers, turning you from a confused buyer into an informed artist who can confidently select the perfect tattoo needle cartridge.

Why Understanding Tattoo Needle Codes Matters

Choosing the right needle isn't a guessing game. The wrong configuration can lead to:

• Blowouts and shaky lines
• Uneven shading and patchy color
• Unnecessary skin trauma
• Frustration and wasted time
• Mastering the code allows you to build a predictable, professional toolkit.

Breaking Down the Code: Two Key Parts

Every tattoo needle designation follows a simple logic. It tells you the Needle Type (its shape and purpose) and the Needle Count (its size and number of pins).

Format: [Needle Type] [Needle Count]

Example: RL 07 = Round Liner with 7 pins.

Part 1: Cracking the Needle Type (The Letters)

The letters describe the shape and arrangement of the needles. This is the most critical part of the tattoo needle nomenclature.

Liner Needles: For Sharp, Clean Outlines

RL (Round Liner): The standard for lining. The needles are soldered in a circular formation, creating a sharp point ideal for crisp lines and details.

Use for: All outlining work, fine details, script.

RS (Round Shader): Often confused with RL, but used differently. The needles are also arranged in a circle but are soldered at a longer length, creating a "softer" tip that can hold more ink.

Use for: Traditional bold lines, and sometimes for packing color in small areas.

Shader Needles: For Filling and Soft Effects

M1 (Flat Needles): Needles are arranged in a single straight line. This creates a wide, chisel-like tip that lays down solid lines or can be used for shading.

Use for: Creating straight lines, filling in large color blocks, and some geometric shading.

M2 (Weaved/Magnum): Two rows of needles stacked together. This is a workhorse for coverage.

Use for: Quick, efficient color packing and solid filling.

F/M1 (Stacked Magnum): Two rows of needles that are "stacked" directly on top of each other, creating a denser, more focused grouping than a weaved magnum.

Use for: Smooth, gradient shading, and saturated color packing with less trauma.

RM (Round Magnum): The needles are arranged in a wide, oval-like formation. It combines the filling power of a magnum with the softer feel of a round configuration.

Use for: Soft, painterly shading and blending.

Specialty Needles

FLI (Curved Magnum): The pins are arranged in a curved shape, designed to be gentler on the skin by creating a more ergonomic footprint.

Use for: Artists seeking a more comfortable shading experience for their clients.

Part 2: Understanding the Needle Count (The Numbers)

The number indicates the count of individual pins in the grouping and implies the overall diameter.

Lower Numbers (e.g., 03, 05, 07): Fewer pins, creating a finer grouping.

Example: An RL 03 has 3 pins for ultra-fine lines. An RL 07 has 7 pins for standard lines.

Higher Numbers (e.g., 09, 11, 15, 21): More pins, creating a wider, thicker grouping.

Example: An M2 09 has 9 pins per row (18 total) for small-area filling. An M2 21 has 21 pins per row (42 total) for large-area coverage.Note: The diameter of the individual pins themselves (e.g., #12 for 0.35mm) is also crucial, but that's often a separate specification noted as "Needle Diameter."

Putting It All Together: Real-World Examples

"Gewinner RL 08 (0.25mm)": A Round Liner with 8 pins, made with fine 0.25mm diameter pins. Perfect for most of your outlining work.

"Magic Moon F/M1 13": A Stacked Magnum with 13 pins in total (two stacked rows). Excellent for smooth shading on a medium-sized area.

Conclusion: Knowledge is Power

Decoding tattoo needle configurations is a fundamental skill that elevates your art. By understanding what RL, RS, and M1 mean, you no longer have to rely on trial and error. You can strategically build your kit, selecting the perfect needle grouping for every stage of the tattoo process. This knowledge leads to better results, happier clients, and a more confident you.
