Introduction
The art of tattooing has evolved from hand-poked designs and rudimentary tools to precision-driven, hygienic, and highly engineered practices. While the culture surrounding tattooing is deeply rooted in tradition, the modern tattoo process is a fusion of technical knowledge, bio-mechanics, and artistic finesse.
In this article, we’ll explore the entire journey of a tattoo—from how machines work and how ink is delivered to the skin, to the biological process of healing and long-term pigment retention.

Part 1: Tattoo Machine Mechanics
1.1 Rotary vs Coil Tattoo Machines
Rotary Machines are machines powered by a motor, and usually
Mechanism: Powered by a small electric motor with a rotating cam that converts rotational motion into linear movement.
Performance: Quiet, consistent, lightweight, and versatile. Great for line work and shading.
Maintenance: Minimal. Few moving parts.
Cartridge Compatibility: Almost all rotary machines use modern cartridge systems.
Coil Machines
Mechanism: Use electromagnetic coils to create a magnetic field that pulls a spring-loaded armature bar up and down.
Performance: Heavier and louder. Offers a traditional "punch" feel. Preferred by many traditional artists.
Customization: Tunable for lining or shading by adjusting the spring tension and contact screw.
Parts: Armature bar, contact screw, front and rear springs, coils, frame, capacitor.
Pneumatic Machines
Mechanism: Run on compressed air.
Rarity: Less common, but gaining popularity in specialized studios.
Perks: Lightweight, autoclavable.
SEO Tip: Use phrases like “rotary vs coil tattoo machine” or “how does a tattoo machine work” to rank with beginner audiences.

1.2 Power Supply & Foot Pedal
Power Supply: Delivers steady voltage (typically 4–12V) to the machine.
Foot Pedal: Acts like an on/off switch, giving the artist momentary control of machine operation.
Digital Power Supplies: Allow memory presets, voltage readouts, and consistent performance.
---
1.3 Needle Drive System
Rotary and coil machines use:
Needle Bar System (older style): The needle grouping is soldered to a long bar connected to the armature bar or cam.
Cartridge System (modern): A disposable, self-contained unit that houses both the needle and membrane system for safety and cleanliness.
---
Part 2: Tattoo Ink Delivery and the Skin
2.1 Tattoo Needle Movement
Tattoo machines drive the needle up and down at a frequency of 50 to 3000+ punctures per minute, depending on voltage and stroke length.
The needle rapidly punctures the epidermis (top layer of skin) and delivers ink into the dermis (second layer).
Proper depth is around 1.5–2mm. Too shallow and ink won’t hold; too deep and you risk blowouts or excessive trauma.
---
2.2 Anatomy of the Skin
Skin Layer Description Relevance
Epidermis Outermost layer, constantly shedding Tattoo needle must pass through this layer
Dermis Middle layer; dense with collagen, blood vessels Where ink is deposited and held permanently
Hypodermis Fatty layer Ink here causes blowouts and fades
---
2.3 The Actual Tattooing Process
1. Stencil Placement: Using thermal printers or freehand, the artist applies the design using stencil transfer paper and stencil solution.
2. Skin Preparation: Skin is cleaned with antiseptic, shaved, and wiped again with green soap or alcohol-based cleaner.
3. Machine Configuration: The artist sets up their machine with the appropriate needle, grip, and voltage.
4. Lining: Outlines are usually done first using round liners. Slow, steady passes deposit ink for bold, clear lines.
5. Shading: Done with round shaders or magnums. Whip shading, pendulum shading, or circular motions are used for smooth gradients.
6. Color Packing: Saturating color into the skin using mags or round shaders. The goal is even pigment distribution.
7. Layering & Texturing: Advanced artists build tones using multiple passes, letting each layer settle before adding contrast or highlights.
8. Wiping: Vaseline or glide ointments are used to protect the skin, lubricate the needle’s path, and ease wiping.
9. Final Pass: Once completed, the tattoo is wiped clean, inspected for inconsistencies, and photographed.

2.4 Pain, Trauma & Ink Placement
Tattooing hurts—a controlled injury.
Pain levels depend on:
Body part
Technique
Machine type
Duration
Proper technique minimizes trauma. A skilled artist causes redness and mild swelling without excess bleeding or scabbing.
---
Part 3: Healing, Integration & Long-Term Ink Retention
3.1 Immediate Aftermath
The skin may ooze plasma and ink for several hours.
Most artists apply a barrier film or second skin (like Saniderm or Derm Shield) to protect the open wound for the first 12–48 hours.
If a bandage isn’t used, a thin layer of healing ointment is applied instead.
---
3.2 The Healing Process
Stage Days What Happens
Initial Healing 1–3 Redness, swelling, clear plasma, tenderness
Peeling & Flaking 4–14 Scabbing, itchiness, pigment looks faded
Regeneration 2–4 weeks New skin layers form; color resurfaces
Long-Term Settling Up to 3 months Ink “settles” into dermis, final tone emerges
---
3.3 Ink Integration
Macrophages, part of the immune system, consume excess pigment and carry some away.
Remaining ink particles become lodged in the dermis’ collagen matrix, held between fibroblast cells.
Ink stability is influenced by:
Particle size
Skin type
Depth and evenness of deposit
Aftercare
---
3.4 Tattoo Longevity & Aging
Tattoos fade with time, especially if exposed to UV light.
Lighter pigments fade faster than black or blue.
Key to longevity:
Correct depth during application
High-quality ink
Proper aftercare
Sun protection

The Modern Tattoo Process: From Machine to Skin
Tattooing has come a long way from sharpened sticks and hand-poked pigments. Today, it's a highly technical craft that blends artistic skill with modern engineering, biology, and hygiene. Whether you're a tattoo artist, an apprentice, or simply someone fascinated by the process, understanding how a modern tattoo works—from the inner mechanics of the machine to how ink becomes permanent under your skin—reveals just how complex and remarkable this art form really is.
Let’s take a walk through the tattoo process, starting with the tools, exploring what happens beneath the skin, and finishing with how tattoos heal and last a lifetime.
---
The Heart of the Process: Tattoo Machines
Modern tattooing relies on two primary types of machines: coil and rotary. While both serve the same purpose—driving needles into the skin—they operate in very different ways.
Coil machines are the more traditional option. They use electromagnetic coils to move an armature bar up and down, creating the iconic buzzing sound many people associate with tattooing. These machines offer a “punchier” hit and are often favored by artists working in bold, traditional styles. Coil machines are adjustable and can be fine-tuned to perform specific tasks like lining or shading by changing spring tension and contact screw settings.
On the other hand, rotary machines operate with a small electric motor and a rotating cam. This translates rotational motion into a smooth, consistent linear movement. They're much quieter, lighter, and generally more versatile than coil machines. Rotary machines are especially popular with modern tattooists who use cartridge needle systems, which allow for quick needle changes and streamlined setups.
Regardless of the type, both machines are powered by a regulated power supply that controls the voltage and machine speed. A foot pedal acts like a switch, allowing the artist to start and stop the machine with precision.
---
Ink Delivery: The Role of the Needle
Tattoo needles are grouped together in various configurations—round liners, shaders, magnums—and are attached either via a long needle bar or a disposable cartridge system. As the machine runs, the needle moves up and down at speeds ranging from 50 to 3000+ punctures per minute.
The needle must reach a very specific depth to be effective. Too shallow, and the ink will fade quickly as the upper layers of skin shed. Too deep, and the ink can spread into the fatty tissue, causing what’s known as a “blowout”—where the ink blurs under the skin. The sweet spot is about 1.5 to 2 millimeters below the surface, in the dermis—the second layer of skin.
---
Understanding Skin: Where the Tattoo Lives
To understand how tattoos stay in your body, it helps to understand the skin’s anatomy. There are three primary layers:
The epidermis is the outermost layer. It’s what you see and touch, but it also constantly regenerates, shedding dead skin cells and replacing them with new ones. Ink placed here simply disappears over time.
The dermis lies just beneath and is made up of connective tissue, blood vessels, and collagen. This is where tattoos are placed. The dermis is stable and does not shed, which is why tattoos here can last a lifetime.
Below that is the hypodermis, or subcutaneous fat. Ink that ends up here becomes distorted or spreads, causing unwanted effects.
A properly executed tattoo deposits pigment into the dermis, where it becomes trapped within fibroblast cells. These cells hold the ink in place, creating the appearance of permanent artwork.

The Tattooing Procedure: Start to Finish
A professional tattoo begins with more than just a machine. The first step is consultation and design approval. The client works with the artist to finalize the artwork, placement, and size.
Before any ink touches the skin, the artist prepares the station using medical-grade sanitation practices. Equipment is barrier-wrapped, gloves are worn, and only single-use or sterilized tools are used.
The area to be tattooed is then cleaned and shaved, followed by the application of the stencil using thermal paper or hand-drawn outlines. Once the stencil sets, the artist configures their machine, selects the appropriate needle groupings, and adjusts the voltage according to the work being done.
The tattooing itself usually begins with linework, using round liner needles to lay down the framework of the design. This is often followed by shading, where different needle groupings—like round shaders or magnums—are used to build depth, texture, and gradient. Finally, if the design includes color, the artist proceeds to color packing, carefully layering in pigment for saturation and consistency.
Throughout the process, the artist uses ointment (like petroleum jelly or specialty glides) to protect the skin and ease wiping. The tattoo is worked in sections, with the artist constantly checking for consistency, saturation, and trauma.
Once the tattoo is finished, it’s wiped clean and examined. After taking photographs, the artist typically applies a second skin film or a thin layer of ointment with a breathable bandage.
---
What Happens Next: Healing and Ink Integration
Immediately after a tattoo, the body begins to treat the area like a wound. For the first few days, the tattoo may ooze plasma, ink, and minimal blood—this is a natural part of the healing response. Many artists now recommend leaving a transparent second skin barrier on for the first 24–72 hours to prevent contamination and scabbing.
Once the bandage is removed, the tattoo enters the peeling stage, which feels similar to sunburn. This phase typically lasts from day 4 to day 14 and is marked by itching, flaking, and a temporary dullness in the tattoo. It's important not to scratch or pick at the area, as this can disrupt the pigment.
Over the next few weeks, the outer layer of skin continues to regenerate. The tattoo may look slightly cloudy or faded during this time, but by week 3 or 4, the new epidermis settles and the true color and contrast start to return. Complete healing can take up to 8 weeks, depending on the tattoo’s size, placement, and the individual’s health and aftercare routine.

How Ink Becomes Permanent
So how does ink stay in your skin for decades?
After the initial trauma subsides, macrophages—cells from your immune system—move into the area to clean up debris. Some of these cells ingest pigment particles, while others get trapped in the surrounding collagen matrix of the dermis. The ink that remains is held in place by fibroblasts, which sit beneath the regenerating skin and give tattoos their permanence.
Over time, some ink particles may be broken down or transported away by the lymphatic system. That’s why tattoos fade gradually over decades, especially with sun exposure or poor aftercare.
---
Tattoo Safety and Hygiene
One of the most significant aspects of modern tattooing is its strict safety protocols. Professional tattoo studios are held to high sanitation standards, often exceeding those of minor medical procedures.
Artists use:
Disposable needles and cartridges
Barrier protection for machines, clip cords, and power supplies
Sterile gloves, changed frequently
Hospital-grade disinfectants for surfaces
Proper biohazard disposal methods for contaminated materials
These practices protect both the client and the artist from bloodborne pathogens like Hepatitis B, Hepatitis C, and HIV.

Final Thoughts
Tattooing may seem simple at a glance—just ink and skin—but the modern process is a sophisticated balance of machine technology, biological precision, and artistic intention. From the moment a stencil is laid to the time a tattoo heals fully, every step matters. Understanding how tattoos work not only deepens your respect for the craft, but also helps clients appreciate the skill, effort, and science that go into every needle stroke.
As machines evolve, inks become safer, and techniques refine, the future of tattooing will continue to push the boundaries of what’s possible on the human canvas.
