Prepare clean artwork
Choose dark modules on a light background and download SVG when possible.
Print-quality QR code generator
Use a short final URL, generate the code, and download SVG for layout or PNG for standard office documents.
A three-stage print workflow
Place without altering
Keep the code square, preserve the full quiet zone, and avoid effects or image overlap.
Proof the final object
Scan the actual print at expected distance, angle, light, and surface condition.
Print contexts need different decisions
Cards, labels, and brochures
Short viewing distance allows smaller codes, but paper texture and fine modules still matter.
Posters and window signs
Increase code size for approach distance, glare, motion, and imperfect camera angles.
Packaging and equipment
Account for curvature, ink spread, abrasion, production tolerances, and long service life.
Example: A3 event poster
The designer uses a short schedule URL, 35 mm SVG code, white border, and a plain-language call to action.

Common print-production failures
Cropping the white border
The quiet zone separates the symbol from surrounding text and images.
Using low contrast
Pastels, metallic inks, transparent backgrounds, and reversed colors need careful physical testing.
Resampling a tiny screenshot
Use the supplied SVG or high-resolution PNG instead of enlarging a browser capture.
Testing only the PDF on screen
Print processes and surfaces introduce real changes. Scan the final production proof.
Printing QR codes: FAQ
What is the minimum QR code size?
There is no universal minimum. Around 20–25 mm is a common starting point for short URLs at close range, followed by testing.
How does scan distance affect size?
A useful starting ratio is about 10:1: a code scanned from one meter may need to be roughly ten centimeters wide. Conditions can require more.
Should I use CMYK colors?
Your print workflow may convert to CMYK. Ensure the resulting dark and light areas retain strong contrast, then inspect a proof.
Is high error correction always better?
It adds redundancy but also creates a denser pattern. Use it when damage or a permitted central mark warrants it, not automatically.
SVG or PNG for print?
SVG is preferred for professional layout because it scales cleanly. A sufficiently large PNG can work in office software when not enlarged beyond its pixel dimensions.
