Making a Photostencil with the Sun

The sun is an amazing source for full spectrum UV light.

Using our homemade exposure unit we exposed a screen with the sun to prove it can create quality stencils. We used a our Step Exposure Gauge as well as the professional Autotype Exposure Calculator and a Stouffer Step Wedge to compare our findings.

All three calculators came to the same conclusion for timing and the sun is indeed a viable way to create stencils.
