ExposureStrip Screenprint app analytics for September 2

Calibrate a screen-printing exposure run with evidence instead of memory. ExposureStrip calculates a six-window half-stop test wedge from one base time. Score stencil washout, fine-detail retention, and pinholes to select the strongest compromise. When lamp distance changes, apply inverse-square correction while keeping the required assumptions visible. Keep mesh count, emulsion, reference distance, selected step, and results together. Export a designed PDF exposure proof or CSV step ledger for the darkroom. Physical testing remains essential; the app organizes measurements and calculations rather than claiming to inspect a screen automatically. No account, subscription, in-app purchase, ads, analytics, tracking, cloud sync, or developer-server upload.
