How to choose thermal label paper for printing QR codes?

When choosing thermal label paper for printing QR codes, multiple factors need to be considered to ensure print quality, readability, and durability. Here are some key selection points:

1. Size and specifications

Choose the appropriate size of thermal label paper based on the printer model and paper compartment size. Common sizes of thermal label paper include various diameter and length specifications, such as 85mm diameter.

Ensure compatibility between the size of the selected thermal paper and the printer to avoid improper loading or printing quality issues.

2. Paper quality

Coating uniformity: Choosing thermal paper with uniform coating helps ensure clear and smooth edges of the printed QR code image, improving scanning success rate.

Reaction sensitivity: High quality thermal paper is more sensitive to heat and can achieve clear printing at lower temperatures, reducing wear on the print head.

Paper thickness: A suitable thickness of thermal paper can ensure printing quality and avoid difficulties in feeding or damage during the printing process.

3. Durability

Select the appropriate durability level based on the application scenario. For example, if QR code labels need to be exposed to outdoor or harsh environments for a long time, three or four proof thermal paper with waterproof, oil proof, alcohol proof and other characteristics should be selected.

Consider the shelf life of the labels. High quality thermal paper can maintain clear and durable printed images, suitable for applications that require long-term preservation.

4. Brand and reputation

Choose thermal paper from well-known brands and high-quality evaluations. These brands usually have strict control over product quality and can provide stable and reliable printing effects.

You can refer to the evaluations and usage experience of other users to understand the printing quality, durability, and cost-effectiveness of different brands of thermal paper.

5. Economy

Consider the price and printing cost of thermal paper. Choosing cost-effective products while ensuring print quality can help reduce overall usage costs.

Pay attention to the additional value such as preferential policies and after-sales service when making bulk purchases.

6. Special needs

If the QR code label needs to have special physical characteristics (such as removability, repeatability, etc.), thermal paper with corresponding characteristics should be selected.

For application scenarios that require printing color QR codes, you can choose thermal paper that supports color printing or use other printing technologies.

7. Storage and maintenance

After purchase, thermal paper should be stored properly to avoid adverse conditions such as high temperature, humidity, and direct sunlight that can affect its performance and printing effect.

Check the storage status and expiration date of thermal paper before use to ensure printing quality.

In summary, when choosing thermal label paper for printing QR codes, multiple aspects such as size specifications, paper quality, durability, brand reputation, economy, and special needs should be comprehensively considered. By careful comparison and selection, you can find the most suitable thermal label paper product for your application scenario.
