Print quality directly affects QR code scannability. Understanding DPI, ink behaviour, and paper characteristics prevents costly reprint cycles.

Resolution (DPI)

Minimum DPI by QR code size and version:

QR Size	Version 2 (25 mod)	Version 5 (37 mod)	Version 10 (57 mod)
2 cm	318 DPI	470 DPI	724 DPI
3 cm	212 DPI	314 DPI	483 DPI
5 cm	127 DPI	188 DPI	290 DPI
10 cm	64 DPI	94 DPI	145 DPI

Rule: Each module must be at least 2 pixels wide at print resolution. Lower resolution causes module edges to blur together.

Laser printing: Sharp edges, high contrast, excellent for QR codes. Preferred for small codes on business cards and labels.

Inkjet printing: Adequate for larger codes (3 cm+). Watch for ink bleed on absorbent paper, which merges adjacent dark modules.

Offset printing: Professional quality. Specify minimum dot size to prevent fine modules from dropping out in the plate-making process.

Screen printing: Works for large-format codes. Mesh density must support the module size. Minimum 200-mesh for codes under 10 cm.

Material	QR Code Performance	Notes
Smooth coated paper	Excellent	Best for small, high-density codes
Uncoated bond	Good	Slight ink absorption; use larger modules
Newsprint	Fair	Significant absorption; increase size and EC level
Cardboard	Good	Smooth side preferred
Vinyl/plastic	Excellent	Weather-resistant; matte finish preferred
Metal	Good-Excellent	Laser etching or screen printing
Fabric	Fair	Large modules only; thermal transfer best

Matte lamination: Ideal — reduces glare, preserves contrast
Gloss lamination: Can cause scanning issues from reflective glare
UV coating: Similar to gloss — use selectively (matte spot UV over the QR code)
