Won't Scan
Poor contrast and illegal sizing are the top reasons for scan failure. QRTRAC includes a built-in scannability checker.
Contrast Logic
Background must be 70% lighter than foreground.
Sizing Guard
Automated scaling to maintain minimum cell dimensions.
Scan Simulation
Use QRTRAC's built-in contrast checker before final print.
