A dual-head TIJ printer is an industrial thermal inkjet printing system equipped with two independent print heads that use TIJ (Thermal Inkjet) technology to print directly onto products or packaging surfaces without labels.
How It Works
-
Thermal Inkjet Technology:
Each print head uses tiny heating elements to eject microscopic ink droplets onto the substrate (box, carton, plastic, metal, etc.). This creates high-resolution text, barcodes, QR codes, logos, dates, and other variable data.
-
Dual-Head Design:
With two print heads, the printer can either:
-
Increase print height (by aligning heads vertically for taller prints up to 25.4 mm or more when combined), or
-
Print two different messages simultaneously at separate locations (two lanes or different info on the same product).
Key Features
High-resolution output: up to 600 dpi for clear text and scannable barcodes.
Versatile printing: can print batch codes, expiry dates, QR codes, logos, serial numbers, and variable data.
Multi-surface support: works on cartons, plastics, metals, foils, glass, and many other surfaces.
User-friendly interface: often includes a touchscreen for easy setup and message editing.
Cartridge-based technology: maintenance-free print heads use standard cartridges (like HP TIJ 2.5), making operation clean and quick to service.
Fast and efficient: suitable for inline production lines with conveyor integration and sensors to trigger printing automatically as products pass by.
Typical Uses
Dual-head TIJ printers are widely used in industries like food & beverage, pharmaceuticals, cosmetics, FMCG, and manufacturing for:
-
Batch coding & expiry date printing
-
Barcode and QR code printing
-
Brand logos and product info
-
Variable data marking for traceability
