Here are some of the best practices for printing QR Codes:
Ensure Sufficient Size: QR codes should be large enough to be scanned easily by smartphones. A good rule of thumb is to ensure that the QR code is at least 3 x 3 centimeters (about 1.2 x 1.2 inches) in size.
Maintain Proper Contrast: Ensure there is enough contrast between the QR code and the background to ensure readability. A high contrast ratio between the QR code and its background makes scanning easier.
Use High-Quality Printing: Always use high-quality printing materials and techniques to avoid blurring or smudging, which can render the QR code unreadable. High-resolution printing ensures clarity and accuracy.
Choose the Right Material: Consider where the QR code will be placed and choose a printing material suitable for that environment. For example, if the QR code will be outdoors, use weather-resistant materials to prevent damage from rain or sunlight.
Test Before Mass Printing: Before printing a large batch of QR codes, test a few samples to ensure they can be scanned accurately with various devices. This helps identify any issues early on and prevents wasted resources.
Include a Call to Action: If the QR code is part of a marketing campaign or informational material, include a clear call to action instructing users on what to do with the QR code (e.g., "Scan here for more information").
Avoid Distortion: Ensure that the QR code remains undistorted during printing. Stretching or skewing the QR code can make it difficult for scanners to read.
Provide Margins: Leave some white space or margin around the QR code to prevent interference from nearby graphics or text, which could disrupt scanning.
Error Correction: Use error correction when generating QR codes. Error correction allows the QR code to remain scannable even if it's partially damaged or obscured. Choose an appropriate error correction level based on the intended usage and environmental factors.
Placement and Orientation: Place the QR code in a prominent location where it's easily visible and accessible to the target audience. Consider the orientation of the QR code and ensure that it's positioned such that scanning is convenient, avoiding awkward angles or positions.
