Continuous Inkjet (CIJ) Printers
Continuous Inkjet (CIJ) printers are industrial coding systems used to print information such as batch numbers, expiry dates, barcodes, and production codes directly onto products or packaging during manufacturing.
They are widely used because they can print at very high speeds without touching the product, making them ideal for fast-moving production lines.
How CIJ Printing Works
CIJ printers create a continuous stream of microscopic ink droplets.
Selected droplets are electrically charged and directed onto the product to form text, numbers, or codes, while unused droplets are recycled back into the system.
This allows printing without stopping or slowing down the production line.
High-speed printing
for fast production lines
Non-contact printing
on uneven or delicate surfaces
Works on many materials
including plastic, glass, metal, and cardboard
Reliability
in industrial environments
Minimal downtime
with automated maintenance systems
Typical Uses
CIJ printers are commonly used to print:
- Expiry and best-before dates
- Batch or lot numbers
- Production codes
- Barcodes and QR codes
- Serial numbers
These markings help businesses maintain product traceability and regulatory compliance.
