What is Thermal Inkjet (TIJ) Technology?
Thermal Inkjet (TIJ) technology is a widely used industrial printing method known for its high resolution, simple design, and minimal maintenance requirements. Commonly applied in packaging, food, beverage, electronics, and pharmaceutical industries, TIJ printers offer clean, sharp prints ideal for coding and marking applications.
How Thermal Inkjet (TIJ) Technology Works
TIJ printers operate by rapidly heating a small volume of ink within a nozzle chamber. The heat creates a vapor bubble that forces a tiny ink droplet out of the nozzle onto the substrate. This process occurs at extremely high speeds—thousands of times per second—enabling precise, high-resolution printing.
Key Features of TIJ Technology
- High Resolution: Prints at 300–600 dpi or higher, perfect for small text, logos, barcodes, and DataMatrix codes.
- Compact and Lightweight: TIJ printers are compact, allowing easy integration into tight production spaces.
- Maintenance-Free: Each cartridge includes a new printhead, eliminating the need for mechanical service or replacement parts.
- Environmentally Friendly: Typically uses water-based or ethanol-based inks with low VOC emissions.
- Versatile Substrate Compatibility: Prints on paper, cardboard, wood, and with special inks, even on plastics, metals, and coated materials.
Common Applications of TIJ Printers
- Food and beverage packaging coding (expiry dates, batch numbers)
- Pharmaceutical and medical product serialization
- Electronics component marking (PCBs, cables, batteries)
- Personal care and cosmetics packaging coding
- Industrial labeling and barcode printing
Advantages of TIJ Technology
- Excellent Print Quality: Consistent, sharp, and scannable codes.
- Low Startup Cost: Affordable systems with minimal setup complexity.
- No Regular Maintenance: Cartridge replacement refreshes the printhead.
- Clean Operation: No risk of leaks or solvent fumes compared to some CIJ systems.
- Flexible Message Changes: Easily updated through touchscreen controllers or network systems.
Limitations of TIJ Technology
- Limited throw distance (typically 2–5 mm), requiring precise alignment with the substrate.
- Cartridge-based systems mean higher consumable cost compared to bulk ink systems.
- Ink selection is critical for adhesion on non-porous surfaces like glass or metal.
- Not ideal for extremely high-speed, continuous production compared to CIJ printers.
FAQs
- Can TIJ printers replace CIJ printers? TIJ is ideal for high-resolution coding at medium to high line speeds but is not a complete replacement for CIJ in ultra-high-speed, harsh environments.
- What substrates are best for TIJ printing? Porous and semi-porous materials like cardboard, paper, wood, and some treated plastics are best for TIJ applications.
Conclusion
Thermal Inkjet (TIJ) technology offers a reliable, cost-effective, and high-quality solution for industrial coding and marking applications.
