Best Practices for High Quality Barcode Printing

Barcode printing plays a critical role in many industries, from logistics to retail. Clear, readable and durable barcodes keep the supply chain running smoothly. But what methods should be used to achieve the highest quality barcode printing? In this article, we’ll explore the best techniques for high-quality barcode printing.
1. Choosing the Right Printing Technology
The technology used in barcode printing has a major impact on the readability and durability of the barcode. The most common barcode printing technologies are:
a) Thermal Transfer Printing
Thermal transfer printing is one of the most common methods for achieving durable and long-lasting barcodes. Ribbon-based printing creates labels that are resistant to water, heat and chemicals.
b) Direct Thermal Printing
This method does not use ribbon and the printing paper is heat sensitive. It is suitable for short-lived barcodes but can be erased over time as it is sensitive to heat and light.
c) Laser Printing
Barcode printing with laser printers provides very detailed and clear prints. Suitable for businesses with high volume printing needs.
d) Inkjet (Ink Pummeling) Printing
Inkjet technology is ideal for flexible packaging and curved surfaces. It can print fast and clean, but there is a risk of smearing on some surfaces.
2. High Quality Barcode Design
Barcode design is one of the most important factors affecting print quality. Things to pay attention to:
- Choosing the Right Barcode Type: The barcode format suitable for the intended use should be determined (QR code, EAN, UPC, Code 128, etc.).
- Appropriate Size and Spacing: Sufficient space must be left for the barcode to be readable.
- Use of Contrast and Color: Black and white contrast works best. Low contrast can reduce readability.
- Correct Font and Character Usage: The text below the barcode should be easy to read.
3. Selection of Quality Materials and Inks
The material and ink used in barcode printing affects readability and durability.
- Paper and Plastic Labels: Plastic-based labels are more resistant to water and chemicals.
- UV Resistant Ink: UV resistant ink should be preferred for barcodes to be used in outdoor environments.
4. Testing Barcode Quality
Once the barcode has been printed, barcode scanners and quality control software should be used to test its readability. Compliance with the ISO/IEC 15416 standard must be checked.
5. Maintenance and Calibration
Periodic maintenance and calibration of printing machines helps to keep print quality consistently high. Printheads need to be cleaned and printer settings optimized.
Conclusion
High quality barcode printing is made possible by choosing the right printing technology, using quality materials and applying appropriate design principles. The best practices mentioned above should be followed to improve the readability and durability of the barcode.
