Autotype Exposure Calculator

The Autotype Exposure Calculator helps establish an exposure time for a new emulsion, mesh, lamp, or coating method. A single test screen carries multiple exposure levels, allowing the operator to compare stencil hardness, detail, and washout instead of guessing at one setting after another.

Use it whenever a major darkroom variable changes. The best result holds fine detail, clears cleanly, and does not leave soft or slimy emulsion in the open mesh.
