Why Tattoo Artists Use Multiple Machines: Lining, Shading, and Coloring Demystified

If you think a tattoo is done from start to finish with just one magical machine — think again. Any experienced tattoo artist will likely have two or three machines on their station. Not because they’re indecisive, but because each machine plays a unique role in the tattoo process.

In this article, we’ll break down why tattoo artists switch machines mid-session, how each one functions, and how these choices impact the quality of your future tattoo.

One Machine? Technically Possible, But Not Ideal

Yes, it’s technically possible to do a full tattoo with just one machine — but that’s like painting a mural with only one brush. It’s inefficient, time-consuming, and limits the quality of detail.

In a typical tattoo, there are three core stages:

1. Lining — creating the bold or fine outlines
2. Color Packing — filling in solid areas with pigment
3. Shading — building smooth gradients and depth

Each stage demands different settings, stroke lengths, needle types, and pressure. And that’s where different machines come in.

The Lining Machine: Precision and Power

Purpose: Drawing clean, bold lines that define the shape and structure of the design.

Common setup:
• Coil machines tuned for lining, or
• Rotary machines with a shorter stroke (~3 mm), designed for fast, strong hits.

Characteristics:
• Fast speed
• Sharp, deliberate needle penetration
• Ideal for small round liner needles (3RL, 5RL, 7RL)

Why separate it: A machine that’s perfect for lines will be too aggressive for shading or coloring — risking skin damage and uneven fill.

The Packing Machine: Even and Saturated

Purpose: Applying solid blocks of color or black ink into the skin with consistency and depth.

Common setup:
• Rotary machine with a longer stroke (3.5–4 mm) and softer hit
• Or a dedicated coil shader adjusted for heavier work

Characteristics:
• Consistent, smooth motion
• Less trauma to the skin
• Uses magnum needles (M1, M2) for wide coverage

Why it matters: Using a liner to pack color can lead to overworked skin, excessive bleeding, and slower healing — not to mention patchy results.

The Shading Machine: Soft and Smooth

Purpose: Creating gradients, volume, and subtle depth — crucial in realism and black & grey styles.

Common setup:
• Rotary or pen-style machines with the softest possible stroke and minimal vibration
• Often combined with digital power units for fine-tuning

Characteristics:
• Gentle needle motion
• Designed to “brush” pigment gradually
• Works best with soft mags or round shaders

Why it needs its own machine: Shading is about finesse. A liner machine would hit too hard, while a shader allows artists to build layers without damaging the skin.

Can One Machine Do It All?

Sure. Especially for smaller or minimalistic tattoos. Many beginner artists or traveling professionals work with just one versatile rotary machine. But:

• It takes more time due to constant re-adjustments
• It’s harder to achieve the same precision
• The results may suffer on complex pieces

That’s why most professionals prefer a multi-machine setup — it’s not luxury, it’s efficiency.

Types of Tattoo Machines Explained

Each machine has its strengths. Many modern artists combine types depending on style and preference.

Why Multiple Machines Improve the Workflow

In a professional setup, you’ll often see two or more machines pre-loaded and ready to switch at a moment’s notice. Here’s why:

• Saves time during sessions
• Avoids reconfiguring the machine every few minutes
• Allows the artist to stay “in the zone”
• Reduces risk of technical errors or injury to the skin

It’s like a chef switching knives depending on what they’re cutting — not out of vanity, but necessity.

One Machine Isn’t Bad — But It Has Limits

Some artists use a single machine for everything — especially in styles like linework, dotwork, or micro tattoos. In these cases, versatility matters more than speed.

But for large-scale pieces or highly detailed designs, separate machines are usually a sign of professionalism, preparedness, and quality focus.

Final Thoughts

A good tattoo is all about the right tools used the right way. Each machine has a purpose: clean lines, bold color, soft gradients. When an artist uses multiple machines, it’s a sign they’re serious about their craft — and about your skin.

So next time you sit down for your tattoo session and see three machines on the table, know this: you’re in good hands.

It’s not just a tattoo — it’s a process. And every step deserves the right tool.
