Common Mistakes with Scannable Codes for Posters: How to Avoid Them
Scannable codes, such as QR codes and NFC tags, have become a popular way to enhance poster designs and provide additional information to viewers. However, if not used correctly, these codes can be frustrating and ineffective. In this article, we will discuss common mistakes to avoid when using scannable codes for posters, and provide tips on how to use them effectively.
Mistake 1: Poor Code Placement
One of the most common mistakes with scannable codes is poor placement. Codes should be placed in a location that is easily visible and accessible to viewers. Avoid placing codes in corners or edges of the poster, as they may be difficult to scan. Instead, place them in a prominent location, such as the center or top-right corner of the poster.
Mistake 2: Insufficient Code Size
Another mistake is making the code too small. A code that is too small may be difficult to scan, especially for viewers with older smartphones. Ensure that the code is at least 1 inch (2.5 cm) in size to make it easily scannable.
Mistake 3: Incorrect Code Resolution
Using a low-resolution code can also lead to scanning issues. Ensure that the code is printed at a high enough resolution to be easily readable. A minimum resolution of 300 dpi is recommended.
Mistake 4: Lack of Instruction
Viewers may not know what to do with a scannable code, so it’s essential to provide clear instructions. Add a brief message or arrow pointing to the code, indicating what action to take (e.g., "Scan to learn more" or "Scan to watch a video").
Mistake 5: Broken or Incorrect Links
A scannable code is only useful if it links to a working website, video, or other online content. Ensure that the link is correct and functioning properly before printing the poster. Test the code multiple times to ensure it works as expected.
Mistake 6: Inconsistent Code Type
Using inconsistent code types, such as mixing QR codes and NFC tags, can confuse viewers. Stick to one type of code throughout the poster to avoid confusion.
Mistake 7: Lack of Alternative Information
Not all viewers may have a smartphone or be able to scan the code. Provide alternative information, such as a website URL or phone number, for viewers who cannot scan the code.
Best Practices for Using Scannable Codes
To get the most out of scannable codes for posters, follow these best practices:
- Use a clear and concise call-to-action (CTA) to instruct viewers on what to do with the code.
- Ensure the code is easily visible and accessible.
- Test the code multiple times to ensure it works as expected.
- Use a high-resolution code and print it at a sufficient size.
- Provide alternative information for viewers who cannot scan the code.
- Keep the code simple and avoid using complex or custom codes that may not be compatible with all devices.
Conclusion
Scannable codes can be a powerful way to enhance poster designs and engage viewers. However, common mistakes can lead to frustration and ineffectiveness. By avoiding poor code placement, insufficient code size, incorrect code resolution, lack of instruction, broken or incorrect links, inconsistent code type, and lack of alternative information, you can create effective scannable codes that drive results. Remember to follow best practices, test your codes, and provide clear instructions to get the most out of your scannable codes for posters.
