3. How Does a Tattoo Gun Work?

A tattoo gun works by using a motor or electromagnetic coils to move a needle rapidly in and out of the skin, depositing ink into the dermis layer. The needle punctures the skin thousands of times per minute, creating tiny wounds that hold the ink in place. The depth and speed of the needle can be adjusted to achieve different effects.

• Needle Movement: The needle’s reciprocating motion is crucial for depositing ink effectively. In coil machines, electromagnetic coils pull and release an armature bar, which in turn moves the needle. In rotary machines, a motor rotates a cam that pushes and pulls the needle. The speed and stroke length can be adjusted to control the amount of ink deposited.
• Ink Deposition: As the needle punctures the skin, it carries ink from a reservoir in the tube. The ink is deposited into the dermis, the layer of skin beneath the epidermis. The dermis is stable and doesn’t shed like the epidermis, allowing the tattoo to remain visible for a long time.
• Depth Control: The depth of needle penetration is critical for a successful tattoo. If the needle goes too deep, it can cause excessive bleeding and scarring. If it doesn’t go deep enough, the ink may fade or disappear over time. Experienced artists carefully adjust the needle depth to ensure optimal ink placement.
• Speed Adjustment: The speed of the tattoo machine, measured in hertz (Hz) or cycles per second, affects the tattooing process. Higher speeds are typically used for fine lines and shading, while lower speeds are used for packing in color and creating bold outlines. Artists adjust the speed according to their technique and the desired effect.
