Use the skin dimple test to find the best air pressure for painting miniatures with paint thinned to a milk-like viscosity.

Creating the perfect finish for your miniature painting project involves various factors, among which air pressure plays a crucial role. While paint viscosity is a subject frequently discussed, the right air pressure is often overlooked. However, achieving optimal air pressure for your airbrush can make a significant difference in the quality of your work.
The Skin Dimple Test provides a quick and efficient way to calibrate the air pressure. With paint thinned to a milk-like viscosity-a widely acknowledged standard for miniature painting-place your airbrush nozzle close to the skin on your forearm. Gradually increase the air pressure and start spraying until you notice a slight dimpling effect on the skin. This visual cue indicates that the air pressure is strong enough to atomize the paint but gentle enough to maintain control. For most airbrush models, this “sweet spot” usually lies between 15 to 20 PSI (pound-force per square inch).
Calibrating your airbrush to this specific pressure range will give you a balanced output, ideal for intricate details without causing overspray or a spattering effect. This method minimizes the potential pitfalls that can ruin your miniature painting, such as spider-webbing or pooling.
In summary, the Skin Dimple Test is an effective way to gauge the ideal air pressure for your airbrush when painting miniatures, ensuring a finish that is both accurate and aesthetically pleasing. It adds a layer of precision to your work, allowing you to focus on the artistic aspect rather than wrestling with technical difficulties.
