How to Add a QR Code to Your Flyer or Poster (and Test It Before You Print)

What is the Function of a QR Code in a Flyer or Poster?

QR code bridges the gap between a physical design and digital data. Instead of manually entering a website URL, users scan the code with their smartphone camera to access the webpage.

For instance, a restaurant could link to its menu, and a school could link to its event registration form.

Other common uses include:

• • Event information: Provide the dates, locations, tickets, and registration forms.
• • Business lead magnet: Drive the reader to product pages, information, or contact forms.
• • Restaurants: Open online menus and order pages.
• • Schools: Drive the reader to class materials, events, or sign-up forms.
• • Promotions: Drive the reader to a campaign page, discount information, or product offers.

How to Add a QR Code to a Flyer or Poster

Follow these four steps to add a QR code to your design and prepare it for print.

Step 1: Choose the page your QR code will open

First, decide what readers should see after scanning the code. Choose the site that gives them the desired information or lets them continue.

For example, an event poster may link to the ticket page, while school advertisement posters can open registration forms.

Before you start designing the code, make sure that:

• • The webpage is accessible on a mobile device.
• • The information is accurate and up-to-date.
• • The webpage doesn't require logging in unless necessary.
• • The primary action is easily identifiable.
• • The web address starts with HTTPS, if possible.

Copy the final web address. Make sure there are no mistakes in it before making the QR code.

Step 2: Create the QR code

Use a QR code generator that can accommodate the type of link you wish to use.

The typical steps in generating a QR code are as follows:

• 1. Launch the QR code generator program.
• 2. Choose the URL or website option.
• 3. Input the link of the destination site.
• 4. Generate the QR code.
• 5. Download the QR code as an image.

Step 3: Add the QR code to your design

Now take out the flyer or poster that you have designed in your design software. Insert the QR code and arrange it in such a way that the viewers can see it clearly.

QR code should never be distorted, resized, or cropped in any way; it should always be in its square form.

Make sure to give enough space around the code on all four sides. This space is called the quiet zone. Per DENSO WAVE's technical specifications, leave a minimum of four small squares of space on all four sides of the QR code.

Step 4: Add a clear call to action

The call to action helps readers understand the reason why they should scan the code. They might be unaware of the purpose and destination of the code without it.

Place the call to action close to the code, for instance:

• • Scan to register
• • Scan to see the menu
• • Scan to learn about the event
• • Scan to get directions
• • Scan to browse the collection

Make sure that the text matches the destination page.

Do not promise any discounts or gifts unless the destination page offers them.

Where Should You Place a QR Code on a Flyer or Poster

The QR code should be placed where it is visible and can be easily scanned by the reader using his or her phone.

For a handout, a good place for the code is the bottom, so readers can scan it after reading the message. For a poster, place the QR code at an appropriate height.

Some things to consider:

• • Keep the code visible: Avoid hiding it in small text or decorations.
• • Leave space: Keep nearby text, logos, borders, and images outside the quiet zone.
• • Think about viewing distance: From several feet away, a poster code needs more room than a handout code.
• • Proper Code Placement Guidelines: Avoid folds, cut lines, and curved surfaces while placing the code.
• • Clear background: A solid light panel can distinguish the code from busy designs.

Consider where readers will use printed materials. Printed flyers require different scanning than wall posters.

What Size Should a Printed QR Code Be?

• • Larger codes are easier to scan from a distance, but they also need enough space for the full code pattern and its quiet zone.
• • There is no one-size-fits-all approach for every flyer and poster.
• • Design a code that is easily scannable at arm’s length.
• • Create a code that a seated person can easily scan.
• • Design a code that is big enough for the distance at which it will be viewed.
• • Test the code at the distance from which it will be scanned.

How to Design a QR Code That Scans Easily

QR codes need a distinct pattern, sufficient contrast, and ample space surrounding them. Effective design lets users scan it on the first try.

Follow these design rules:

• • Use dark hues on light backgrounds: Starting with black on white is safe.
• • Keep the QR Code Area Clear: Avoid placing text, shapes, and images near the code.
• • Avoid poor contrast: Pale and similar tints can hide the design.
• • Maintain the pattern: Avoid stretching, blurring, or cropping the code.
• • Use a Solid Background for Better Scanning: Photo or textured surfaces can hide code. A solid panel distinguishes it from the design.

How to Test a QR Code Before Printing

Test both the QR code and the page it opens. A successful scan is only the first part of the check. The destination must also work as expected.

Check the link

Scan the code using a reliable QR code scanner and confirm that it opens the correct page. Check the page on a phone and make sure the main content loads.

If the page includes a form, booking system, or purchase button, test that feature too. A code that opens the wrong page or leads to an error still creates a poor experience.

Test the design on different phones.

Use more than one phone if possible. Try the built-in camera app on an iPhone and an Android phone. Confirm that both can detect the code and open the destination.

Test the code at the size and distance people will use in real life. Do not rely only on a preview on your computer screen.

Print and test a sample

Print a proof before approving the full order. Use the same paper or material, print size, and finish planned for the final job.

Check the sample under normal lighting. Hold the phone at a natural distance and scan the code from the angle a reader is likely to use.

Look for these problems:

• • The phone struggles to detect the code.
• • The printed pattern looks blurry or broken.
• • The paper or finish causes glare.
• • The code is too small to scan comfortably.
• • The destination page opens slowly or displays incorrectly.

If the code fails, fix the design or link and print another proof. Test the new version before sending the final file to the printer.

Common QR Code Printing Problems and How to Fix Them

QR code printing issues can be caused by inadequate contrast, limited space, poor image quality, or the wrong destination.

• • The phone does not recognize the code: The code is either too small, blurred, or distorted. Make it larger and use a more precise image.
• • The code can only be scanned from a very short distance: The code is too small to be scanned from that distance. Make it bigger and try again.
• • The code becomes part of the design: The contrast between the background and foreground is low. Use a dark code on a light background. The text or artwork overlaps the code.
• • There is no quiet zone: Add a white border around the code.
• • The code redirects to the wrong page: The wrong destination is used to encode the code. Check the destination and print a new code.
• • The code works fine on-screen but will not work when printed: Printing results in low resolution or reduced contrast. Print the proof and test the output.
• • The logo makes scanning the code difficult: The logo takes up most of the pattern space. The logo should be reduced or removed and tested again.

Final Pre-Print Checklist

Prior to submitting your flyer or poster to the printer, make sure that each of the following items is completed:

• • QR code leads to the desired destination.
• • Destination page functions on a phone.
• • Pattern is clear and has not been distorted.
• • Code has good contrast with the background.
• • Call to action clearly states what the readers will receive.
• • At least two phones have been used for testing, whenever possible.
• • Proof of the printed version of the code has been scanned.
• • The print-ready file includes the tested version of the code.

A QR code is ready for printing if it links to the right page and works well under its intended use conditions. Make the code, integrate it into your design, and test the printed proof prior to printing the whole batch.
