Exposure time calculator

Estimate a solid starting exposure time for your screen, then generate a step test strip.

Mode

Reference mode adjusts mainly distance + power from a time you already know.

Also apply corrections (emulsion / stencil / mesh)

Enable only if your reference was not done with the same emulsion/stencil/mesh.

The thicker the stencil, the longer the exposure. Always validate with a test strip.

Number of steps

Expose in steps around the recommended time, then pick the best result.

This is an estimate and a starting point. Always run a test strip (or step wedge) to calibrate your exposure.
