Color and contrast: How to ensure QR code visibility
Getting the colors right is critical to ensuring your QR code is scannable.
The most common mistake is poor contrast between the QR code and its background. If the colors blend or are too similar, your QR code won’t scan, leading to frustrated customers and missed opportunities.
The best practice is simple: use a dark QR code on a light background. Black on white is the classic choice, but other dark colors like navy, dark green, or maroon work well too. Avoid light-colored codes on light backgrounds, as they can be challenging to scan.
Stay away from complex or gradient backgrounds. While they may look appealing, they can interfere with the scanning process. If you want a colorful background, ensure it’s still light and doesn’t disrupt the QR code’s readability.
Following these basic color and contrast rules will ensure your QR code remains functional across all printed materials.
✅ To create an effective strategy, identify key touchpoints
Think about where your audience interacts with your brand. Use QR codes in both environments to give your audience more ways to engage, whether scanning a flyer or clicking on a digital ad.

Testing QR codes before printing
Before sending your QR code to print, testing it across all devices is essential to ensure flawless functionality. A quick, step-by-step process can help you avoid issues down the line:
- Test on multiple devices
Scan your QR code using both iOS and Android smartphones. Ensure it works smoothly with different cameras and QR code reader apps. - Check for different lighting conditions
Scan the QR code under different bright and dim lighting scenarios to see how it responds. - Test distance and size
Ensure your QR code scans easily from a reasonable distance, especially for larger formats like posters and billboards. - Check functionality after resizing
If you’ve resized the code for print, retest it to confirm that the changes haven’t impacted scanability. - Test custom QR code shapes
If you decide to use a non-standard shape for your QR code, it’s essential to test it extensively.
By taking these simple steps, you can prevent costly mistakes and ensure your QR codes are ready for all users and devices.
Special considerations for large-scale prints
Ensure scanability when printing QR codes for large-scale formats like posters and billboards. Here are key considerations to keep your codes functional and easy to scan, even from a distance.
- Adjust for viewing distance
For larger formats, you need to increase the size of your QR code based on the expected viewing distance. A good rule of thumb is to increase the code size by 1 cm for every meter of viewing distance. For example, a billboard viewed from 10 meters away should have a QR code at least 10 cm wide. - Test for scanning
Before finalizing your print, test the QR code at the intended viewing distance and make sure it scans quickly on different devices. You don’t want users struggling to scan from far away, which could result in missed engagement opportunities. - Use high-contrast colors
Even minor color errors can affect scanability on large formats. Ensure your QR code contrasts sharply with the background. Dark colors on light backgrounds work best to ensure easy scanning. - Maintain the quiet zone
Like smaller prints, your QR code needs a quiet zone (clear margin) around it. Avoid placing text, images, or design elements too close to the code, which could confuse scanning apps.
Consider these factors to ensure that your QR codes on large-scale prints are highly visible and easily scannable. QRCodeChimp provides the right tools to help you create QR codes optimized for all print sizes.
✅ Provide clear calls-to-action
Always include a clear call-to-action (CTA) that explains what users will get when they scan the code, such as Scan for Discount or Explore Our Products.
Dos and don’ts of QR code printing
When printing QR codes, getting it right ensures a smooth experience for your audience and helps you achieve your desired outcomes. Below are some clear dos and don’ts to provide top-notch print results.
Dos of QR code printing
- Ensure proper alignment
Ensure your QR code is printed straight and aligned correctly on the material. Misalignment can make the code difficult or impossible to scan, especially on small surfaces like business cards. - Use high contrast
Always ensure a dark QR code on a light background for easy readability. This contrast is crucial for quick and accurate scanning. A black code on a white or light-colored background works best. - Check resolution
Use high-resolution files like PNG, SVG, or EPS to prevent pixelation. The higher the DPI (dots per inch), the better the print quality. For professional print media, aim for at least 300 DPI. - Add a quiet zone
Ensure there’s enough blank space (quiet zone) around the QR code. Without this margin, the QR code may blend into the background or other design elements, making it harder to scan. - Test the QR code before printing
Before printing in bulk, always test the code on multiple devices and under different conditions. This will save you time and money by preventing reprints due to faulty or unscannable QR codes. - Choose the correct size
When printed, the QR code should be at least 2 x 2 cm (0.8 x 0.8 inches) to ensure scannability.
Don’ts of QR code printing
- Don’t overcomplicate the design
Avoid using too many design elements around the QR code. Overcomplicating the design can distract from the code and reduce its scanability. Keep the design simple and focused. - Avoid poor color combinations
Avoid low-contrast color schemes like light gray on white or pastel shades on pale backgrounds. Such combinations make it difficult for QR readers to detect the code. Stick to darker codes on lighter backgrounds. - Don’t resize without checking
While resizing your QR code to fit a design may be tempting, improper resizing can distort the code and make it unusable. Always check the DPI and test the code after resizing to ensure it scans correctly. - Avoid cluttered backgrounds
Don’t place your QR code on busy or gradient backgrounds. Complex backgrounds interfere with scanning, as the reader struggles to differentiate between the code and the background. A solid, light background is best for clear visibility. - Don’t forget about size
The QR code needs to be appropriately sized for the media. A small QR code on a billboard will not be scannable, while an oversized QR code on a business card looks awkward. Adjust the size based on the distance from which people will scan it.
Following these dos and avoiding the common don’ts can ensure your printed QR codes look professional, function properly, and enhance user experience.
Ensuring long-term durability of prints
Prints can degrade over time, mainly when used in outdoor settings. To prevent fading or damage:
- Use UV-resistant ink
For outdoor posters and billboards, UV-resistant ink prevents fading from sun exposure. - Lamination or protective coating
Consider applying a lamination layer to protect the print from rain, scratches, and general wear. - Material choice
Choose materials like vinyl or metal for durable, long-lasting prints. Using high-quality materials and protective finishes, you can ensure your prints stay intact for months or even years.
Conclusion
To ensure your QR codes work flawlessly, focus on the essentials: use the right file format, avoid distortion, and test across devices. Maintain consistency in branding and provide a clear call-to-action. Most importantly, prioritize testing and quality control at every step.
