How to test QR code scans before ordering printed materials

Keep decorative elements away from the code

When placing the QR image in your design, do not crop its edges or stretch it out of proportion. Keep text, patterns, and lines out of the blank space around it. A large logo added to the center can also affect readability. To reinforce your branding, consider using the surrounding headings and color areas instead of altering the code itself.

Use the clean original QR file rather than repeatedly copying screenshots of the design. Do not rely on one universal measurement when choosing a print size; the density of the encoded link, production quality, and scanning distance matter. Make a physical sample at your chosen size and verify it where it will be used.

Make the sample representative of the final material

Paper from an office printer may behave differently from the glossy card you plan to order. If possible, ask the printer for a sample close to the final material. If you will use a stand, put the sample inside it. Reflections from the plastic surface or curling at the edge of the card can reveal problems that do not appear on uncovered paper.

Run the test on the final design. Shrinking or moving the code, or adding a new finish afterward, may invalidate the earlier approval. Give the file a descriptive version name; for example, keep the table card and entrance poster in separate files. Each type of printed material should have its own check.

Test a range of scanning situations

Do not test only with the designer’s phone. Use the cameras on different phones available at the business to scan the code. Approach the table with the phone as an ordinary customer would. If you constantly need to turn the code by hand or place the camera in one exact position, reconsider the placement.

Record daylight, evening, and, if applicable, terrace conditions separately. Reflections in very bright light and problems in low light may need different solutions. Testing the sample alongside objects used during meal service reveals shadows and obstructions that are easy to miss on an empty table.

• Does the camera recognize the code?
• Is the link notification clearly readable?
• Can the customer complete the scan without lifting the stand?
• Does the same design work in different lighting positions?

Verify the content behind the scanned link separately

When the camera detects the link, only the first half of the print test is complete. Open it and check the business name, branch, language, and product list. A code that opens a test menu or an unpublished page may be technically scannable, but it does not meet the customer’s need. Mixed-up files across multiple branches make this risk particularly relevant.

Try opening the menu with one phone connected to the venue’s Wi-Fi and another using mobile data. Because the menu needs internet access, you must distinguish connection problems from print problems. If the code scans but the page does not load, inspect the link destination and network access before making arbitrary changes to the design.

Check the first package from the bulk print run too

Do not distribute the delivered prints to every table immediately after sample approval. Select several examples from different parts of the package and check their color, cutting, and links again. This helps you spot problems early, such as the wrong file being printed or part of the code being cut off during production.

Keep the final approved file, its link, and the print date with the business’s menu records. Share this file when reordering instead of simply asking for ‘the same as the old card.’ If the menu address has changed, remember to verify again that a print approved in the past still works correctly today.
