Perfect Print QR
A technical deep-dive for designers into vector exports and dot-density for professional media.
A QR code that doesn't scan is a design failure. In the world of high-end print, resolution and vector paths separate the amateurs from the pros.
Vector (SVG) vs. Raster (PNG)
When you're designing for 300 DPI or higher (commercial print), you should always use vector formats. PNGs and JPGs have "noisy" edges that can confuse a smartphone's sensor, especially at small sizes or on textured paper.
SVG / PDF
Infinite scalability. No pixels. Crisp edges at any size, from a coin to a billboard.
PNG / JPG
Fixes resolution at birth. If scaled up, edges become blurry (anti-aliased) which breaks scans.
Density: The Silent Killer
Static QR codes get more "dots" as you add more data (longer URLs). This called High Density. High-density codes are much harder to print and harder to scan from a distance or in low light.
Designer Secret: Always use Dynamic QR Codes for print. Because they only contain a short redirect link, the code pattern remains simple (Low Density) no matter how long the final URL is.
Checklist for Print-Ready QR
- Use 100% Black (K) ink—avoid RGB black or rich black to prevent registration shifts.
- Keep a 15% safety margin of white space around the code.
- Always do a "Flash Test" (scan with phone) on a laser-printed proof.
Technical Thresholds: DPI & Scaling
For luxury packaging, high-end magazines, or billboard vinyl, the resolution requirements differ wildly. Designers must understand the physical constraints of the scanning device:

The "Bleed" and Safety Margin
Printers often shift by 1-2mm during the cutting process. If your QR code is too close to the edge of your design, or too close to a fold (like in a tri-fold brochure), it might get distorted or cut off.
The Rule of 4: Always leave 4mm of "Quiet Zone" (empty white space) around your QR code. This space is not just for the printer—it's for the smartphone's AI to recognize the square pattern against the rest of your design's colors and textures.
Indoor Print (Flyers)
Distance: 1-2 feet.

Medium: Gloss/Matte Paper.
Outdoor Print (Banners)
Distance: 10-20 feet.
Size: 10" - 24" (250-600mm).
Medium: Vinyl/Mesh Banners.
Pro-Grade Vector Exports

Start Designing with VectorDesigners' Printing FAQ
Is PDF better than SVG?
Both are vector formats. Our PDF export is ideal for non-designers or direct printing, while SVG is the industry standard for importing into Photoshop, Canva, or Illustrator.
What is L-Correction and H-Correction?
This refers to error correction levels. Low (L) makes the code smaller/simpler. High (H) adds redundancy, allowing the code to be scanned even if 30% of it is damaged or covered by a logo.
Should I use a border?
A subtle border can help draw the eye, but never let it touch the "Quiet Zone." The QR code needs that white space to maintain its scannability threshold.
