Label Overprinting Solutions for Variable Data on Pre-Printed Labels
1. What Is Label Overprinting?
Label overprinting is a widely used technique in the printing, packaging, and manufacturing industries. It refers to overprinting variable data onto pre-printed labels or packaging, including production dates, batch numbers, serial numbers, barcodes, or QR codes.
This technique allows companies to avoid recreating the entire label. By printing variable data only in the reserved blank area, businesses achieve flexible customization and low-cost, high-efficiency label updates.
2. Features and Applications of Label Overprinting
Label overprinting is ideal for situations where a label contains both fixed and variable content. Companies typically purchase custom pre-printed labels with branding, ingredients, or contact information, and then overprint the following at the packaging or production stage:
• Expiration dates
• Batch or lot numbers
• Traceability barcodes or QR codes
• Inventory or logistics-related information
Label overprinting can be done using thermal transfer, direct thermal, inkjet, and other printing methods. It supports flexible, small-batch, and multi-batch updates, significantly reducing inventory and waste.
Typical applications include the food, cosmetics, pharmaceutical, chemical, manufacturing, and warehouse logistics industries.
For example, a company purchases bulk color-printed labels with only fixed branding and basic information, leaving part of the space blank. When products are ready for shipment, a direct thermal or thermal transfer printer is used for overprinting onto the pre-printed labels, adding batch information, expiration dates, barcodes, or QR codes—delivering flexible and accurate variable data management.
