Prepare QR codes for reliable printing
A QR that scans on a monitor can fail after printing if size, contrast, margins or the production process are not controlled.
For packaging, labels, badges, print shops and any production where a bad scan becomes expensive after printing.
- Vector SVG
- 300/600 DPI PNG
- White background by default
- 4-module quiet zone by default
- Preview and proof workflow
A clear path from source data to QR assets
1. Set physical size
Choose dimensions appropriate to payload density and scan distance.
2. Keep strong contrast
Black on white remains the safest default.
3. Keep clear margins
Do not let text, frames or artwork touch the QR.
4. Print a proof
Test the actual substrate and printing process before mass production.
Output format guide
A simple example showing how source data stays linked to the generated QR asset.
| Output | Use |
|---|---|
SVG | Vector print / design |
PNG 600 DPI | Demanding raster print |
PNG 300 DPI | Documents and screens |
The whole print chain matters
Paper, substrate, ink, finishing and reduction can all affect readability.
MassQR provides clean source files, but physical proofing is still required.
Avoid transparent backgrounds over busy artwork unless final contrast is fully controlled.
Frequently asked questions
Do I always need 600 DPI?
No. DPI matters for raster output. SVG remains vector. Use the resolution required by your print workflow.
Why keep a white quiet zone?
It helps scanners separate the QR symbol from surrounding graphics.
