Copy-Resistant QR Generator

Generate micro-structured QR codes with moire mesh and deterministic jitter. Use the microscope view to validate line separation and off-grid modules before printing.

Copy-fragility strengthHigher strength increases copy/reprint failure but can reduce original scan margin.

Validate copy-fragility (sim)Runs decode simulations for “print @1200”, “photocopy”, and “scan+reprint” and reports rates (TIFF only).

Custom Configuration SheetUp to 10 variants on a single vector PDF with labels.

Generate Calibration SheetOutputs 5 QR variants with 0–8% jitter for printer testing.
