What file format should I export a QR code in for print?

Vector — SVG or PDF — not PNG or JPEG. A vector file scales to any print size with no blur, while a raster file (PNG/JPEG) can look pixelated once enlarged for something like a poster or banner. Capy QR exports both vector formats free with no watermark.

How big should a printed QR code be?

As a rule of thumb, size the code to roughly a tenth of the intended scanning distance — a code read up close on a business card can be 2cm, while a billboard read from 50 metres needs a code around 5 metres across.

What colors and contrast keep a QR code scannable in print?

Keep strong contrast between the code and its background — dark modules on a light background is the safest bet. Avoid low-contrast color pairings, and always leave a clear quiet-zone margin of blank space around the code so scanners can find its edges.

Does paper stock or finish affect QR code scanning?

Yes — glossy or heavily textured stock can create glare that confuses a phone camera, especially under bright or angled lighting. Matte finishes are generally more reliable. Always test a proof under the actual lighting conditions the code will be scanned in.

Do I need to test a QR code before a print run?

Always. Print a proof at the actual size and material, then scan it with two different phones before committing to a full run — this catches sizing, contrast, or material issues that are expensive to fix after printing.

QR codes for print production (2026 guide)

A QR code that scans perfectly on your laptop screen can fail completely once it's printed — wrong file format, too small, low contrast, or glare from glossy stock. This is a production checklist for getting a QR code from design to a print run that actually works, whatever the surface: a business card, a poster, or a billboard.

File format: always vector

Export as SVG or PDF, never PNG or JPEG, for anything going to print. A vector file scales to any size with perfectly sharp edges; a raster file enlarged beyond its native resolution turns blurry or pixelated — exactly the failure mode that breaks scans on a large poster or banner. Capy QR exports both vector formats free, with no watermark.

Sizing rules

Rule of thumb: size the code to roughly a tenth of the scanning distance. A business card read up close can use a 2cm code; a billboard read from 50 metres needs roughly 5 metres.
Minimum size matters more than maximum. Going too small breaks scans faster than going too large looks awkward.
Leave a quiet zone — a clear margin of blank space around the code — so scanners can locate its edges against surrounding content.

Contrast and color

Dark modules on a light background is the safest, most reliable choice. A styled, colored code can absolutely work — Capy QR's editor supports brand colors and custom dot styles — but the fundamental rule doesn't change: strong contrast between the code and its background. Low-contrast pairings (pale-on-pale, similar tones) are a coin flip on older phone cameras.

Material and finish

Matte over gloss. Glossy or heavily textured stock reflects light and can confuse a camera, especially under angled or bright lighting.
Curved surfaces distort. A code wrapped around a bottle or curved packaging can warp; flat surfaces are more reliable.
Consider the real lighting. A code that scans fine in an office might fail under harsh outdoor sun or dim event lighting — test in the actual conditions.

Always test before the full run

Print a proof at the actual size and material, then scan it with two different phones — different cameras and software handle edge cases differently. This single step catches most print failures before they turn into an expensive reprint of 500 flyers or a full billboard run.
