QR Code Print Resolution
Definition: Print resolution for QR codes is the pixel density required for module edges to stay crisp at the final printed size, normally 300 dpi or a vector file.
Blurred module edges are one of the most common causes of a code that scans on screen but fails in print. The safe route is a vector SVG, which has no fixed resolution and stays sharp at any size. If you must use a raster file, multiply the printed size in inches by 300 to get the pixel dimensions: a 2-inch code needs 600 pixels square. Never enlarge a small PNG to fit a bigger placement. Also watch ink spread on absorbent stock such as newsprint and corrugated card, where modules thicken and can close the gaps — a slightly larger code with high error correction compensates.
Key points
- SVG is the safest format for any print job
- Raster codes need printed inches x 300 pixels
- Never upscale a small PNG for a large placement
- Absorbent stock thickens modules through ink spread
- Ask the printer for a proof and scan it before the full run
Frequently asked questions
What DPI should a printed QR code be?
300 dpi at final size, or use a vector SVG which has no resolution limit.
Why does my printed QR code not scan?
Usually low resolution, insufficient size, weak contrast, or a missing quiet zone.
Is SVG or PNG better for printing QR codes?
SVG. It scales without quality loss and printers prefer it.
