What is the recommended angle to hold a tattoo machine for optimal results?

Holding a tattoo machine at a 45-degree angle is recommended because this position allows for better control over the needle and more effective penetration of the skin. This angle helps optimize the flow of ink into the dermis while minimizing trauma to the skin, ensuring cleaner lines and sharper detailing. Additionally, a 45-degree tilt aids in achieving smoother shading and blending, which is important for the overall quality of the tattoo. Utilizing this angle also promotes efficiency, allowing the artist to maintain comfort during long sessions while effectively managing the machine's performance and the skin's response to the tattooing process.
