How to Choose the Right PMU Machine for You

Start with the work you do most often, then consider how the complete setup supports your technique.

• Your main techniques: Hair strokes, pixel shading, soft blending, and defined lines involve different hand movements and cartridge configurations. Use the techniques you practise as the starting point for comparison.
• Stroke length: Stroke is the distance the needle travels during each cycle. It influences working feel alongside the motor, cartridge, operating settings, and your hand movement.
• Fixed or adjustable stroke: A fixed stroke provides one consistent setting. An adjustable stroke allows you to explore different working characteristics within the machine’s available range.
• Operating controls: Consider how clearly settings are displayed and how easily you can make adjustments. Stroke length and operating speed describe different aspects of needle movement.
• Grip and balance: Compare grip diameter, overall weight, and balance with the battery attached. A comfortable setup should allow you to guide the pen without continually adjusting your hold.
• Daily working hours: Review rated runtime, charging time, and available power options in relation to your usual schedule.

Stroke selection depends on the interaction between the machine, cartridge, and artist’s technique
