Selecting the right coding machine for carton boxes is key to achieving consistent, traceable, and high-quality product identification. Whether you need batch coding, date printing, or QR code marking, the right technology ensures durability and precision across your packaging line.
1. Thermal Inkjet (TIJ) Printers — High Resolution, Easy Maintenance
Thermal Inkjet Printers (TIJ) are widely used for carton printing due to their high resolution (up to 1200 dpi) and clean, non-contact printing. They produce sharp text, logos, and variable data on paperboard, coated cartons, and kraft boxes.
A handheld inkjet printer or portable TIJ printer offers unmatched flexibility for small-batch operations, while inline models integrate easily into automatic packaging lines.
TIJ systems support various ink formulations, including fast-drying pigment inks and UV-curable inks, ensuring strong adhesion and high contrast on porous and semi-porous materials.
2. Continuous Inkjet (CIJ) Printers — For High-Speed Production
Continuous Inkjet Printers (CIJ) remain the industry standard for high-speed, industrial coding. Designed for continuous operation, they print clear, legible marks even on moving or uneven carton surfaces.
CIJ printers are ideal for large-scale batch coding and variable data printing, supporting ERP and MES connectivity for automated data synchronization.
With minimal downtime and strong ink adhesion, CIJ printers are favored in high-volume packaging environments where speed and reliability matter most.
3. Laser Marking — Limited Use for Carton Surfaces
While laser coding machines provide permanent, consumable-free marks, they are not commonly used for paper cartons due to surface abrasion and low contrast.
Laser marking performs best on plastic, metal, or coated substrates where permanent and tamper-proof identification is required.
4. How to Choose the Right System
For sharp, flexible, and low-maintenance printing → choose TIJ inkjet printers.
For continuous, high-speed carton production → go with CIJ printers.
For special materials requiring permanence → consider laser marking.
With the right coding and marking solution, your packaging will maintain clear, compliant, and professional identification from production to delivery.
