What are QR Codes?
A QR code, or 2-dimensional bar code, is a graphic symbol that records data information in black and white contrasting geometric shapes arranged according to a specific rule on a plane (in two-dimensional directions). It has the verification function of a one-dimensional barcode and also has the capability of automatically recognizing information from different lines and handling rotational changes of the image.

How do you create QR codes?
Many clients wish to create their own QR codes but struggle with the design process. Here are some basic steps and suggestions for designing QR codes:
- Determine the Content:
First, decide where and how you will use the QR code and what information it needs to contain, such as a website URL, text, contact information, etc.
- Choose a QR Code Generator:
After determining the content, select an online QR code generator like QR Code Monkey or GoQR.me to design your unique QR code.
- Customize the Design:
- Color: QR codes are typically black and white, but you can create colored ones. However, this requires technical expertise and specific scanning conditions, so black and white is the standard choice.
- Pattern: Many generators allow adding a logo or image in the center of the QR code to enhance brand visibility. Ensure that any added content does not interfere with scanning.
- Shape: The standard shapes for QR codes are square or rectangular, with specific dimensions and ratios for easy recognition by scanners.
- Adjust Size and Borders:
QR codes usually require sufficient white borders for better recognition. Keep this detail in mind when creating the design.
- Test the QR Code:
Once designed, test the QR code with different devices to ensure its effectiveness.
- Quality Control:
When the design is confirmed, choose appropriate materials for printing high-quality QR codes, ensuring the size is suitable and the image is clear for easy scanning.
- Creative Design:
- If you wish to further embellish the QR code, graphic design software (like Adobe Photoshop or Illustrator) can be used for additional editing and enhancing the appearance.
What kind of QR codes labels can we make?
At Liyantian, we provide printing services for indoor and outdoor QR code labels. Customers can choose from various materials, sizes, and purposes.

How do I scan QR Codes?
After your QR code is created, whether in digital format or printed as a label, it can easily be scanned and recognized using a smartphone or scanner.
Difference Between QR Codes & Barcodes
The primary differences between one-dimensional barcodes and QR codes lie in the dimensions and capacity of information storage.
- One-Dimensional Barcodes: These barcodes express information only in one direction (usually horizontally), with no information conveyed vertically. Their height is typically set high for easier alignment by scanners. While one-dimensional barcodes enhance the speed and accuracy of information entry, they have limitations:
- Limited data capacity: About 30 characters, limited to letters and numbers.
- Relatively large size: This means lower space efficiency.
- Vulnerability to damage: Once damaged, they cannot be read.
- QR Codes: A more advanced format than one-dimensional barcodes, storing information both horizontally and vertically, hence called two-dimensional barcodes. Compared to one-dimensional barcodes, QR codes offer:
- Greater information storage: Far exceeding the capacity of one-dimensional barcodes, they can store characters, numbers, and images.
- Wider application range: Due to their ability to store diverse types of information, QR codes are used in more varied scenarios.
- Diverse types of information: They can store URLs, business cards, text, specific codes, etc.
- Versatile application methods: Suitable for both online (like URLs and specific codes) and offline uses (like text and business cards).
In summary, QR codes surpass one-dimensional barcodes in terms of information capacity, diversity, and application fields.
In conclusion, you can customize QR codes based on your needs and purposes. Decide on the usage location, size, whether it should be monochrome or colored, and whether it needs to be printed or generated directly on a smartphone. This way, you can create a unique, personalized QR code. Start creating your own QR code today!
