Tattoo techniques refer to the various methods artists use to create permanent designs on the skin. The most common technique is the traditional tattoo machine, which uses needles to inject ink into the dermis layer of the skin. Artists can create intricate designs by adjusting the speed and depth of the needles, allowing for detailed work and shading. Another popular technique is hand-poked tattooing, where the artist manually inserts ink using a single needle. This method is often favored for its simplicity and the personal touch it brings. Each technique has its unique style and appeal, catering to different preferences among tattoo enthusiasts.
