Test the exposure.
Keep the evidence.
Calculate independent screen-print test times, record what washed out and what stayed, and choose the exposure you want to repeat.
Android edition coming soon. Planned US$4.99 one-time purchase. No Google Play listing is available yet. Android and iPhone/iPad editions are separate purchases.
Score, then decide.
Missing observations stay unscored. The highest comparison score never selects itself. Your chosen result remains an explicit decision.
A record for the next run.
Save a PDF, UTF-8 CSV or JSON record. Share a ZIP with a SHA-256 file manifest. Start a new run from the setup without copying old observations.
Physical tests remain essential.
Each duration is the total for a separate test area, not a cumulative cover schedule. The strip colors are schematic. ExposureStrip does not inspect a stencil, control equipment or guarantee exposure results.
