Raster vs. Vector: Why SVG Matters
Most image formats like JPEG or PNG are raster-based, meaning they are made of a fixed grid of pixels. When you enlarge these files, they lose quality and become blurry, which can make your code impossible for a smartphone to read.
An SVG QR code is vector-based, utilizing mathematical paths rather than pixels. Because of this, it is a truly high-resolution QR code that stays perfectly crisp whether it is printed on a business card or a massive billboard.
Essential Tips for a Printable QR Code
Beyond file format, physical constraints matter. Always ensure your QR code has a quiet zone, which is the clear empty space around the code that helps the camera distinguish it from the background.
Contrast is equally vital. Use a dark foreground color against a light background. Avoid overly busy patterns or low-contrast combinations that might confuse a scanning app.
Minimum Print Sizes and Readability
While vector QR codes look great at any size, they still need to be physically large enough for a camera lens to focus. A good rule of thumb is to keep your code at least 0.8 inches (2cm) wide for small items.
If you are printing for long-distance scanning, such as on a trade show banner or a vehicle, increase the size proportionally so the scan distance is optimized.
