A CIJ inkjet printer, also known as a Continuous Inkjet Printer, is a widely used industrial inkjet printer designed for high-speed, non-contact coding and marking on continuous production lines. It prints variable information such as batch numbers, date codes, and expiration dates directly onto moving products. Well-known CIJ systems from manufacturers such as Meenjet are widely adopted in industrial environments worldwide.
CIJ technology is commonly used as a batch coder, date coder, or inkjet coder in industries including food, beverage, packaging, cable, and pharmaceutical manufacturing.
What Is a CIJ Inkjet Printer?
A CIJ inkjet printer uses a continuous flow of ink to print text, numbers, and simple graphics without physical contact with the product. As a non-contact inkjet marking system, it can print reliably on curved, uneven, or fast-moving surfaces, which is why CIJ equipment from brands like Meenjet is often selected for high-speed production lines.
CIJ printers are widely applied in:
Batch coding machine applications
Date code printer and expiry date printer tasks
Inkjet marking on bottles, cartons, cables, and plastic bags
They are a core component of modern industrial marking systems and industrial marking solutions.
How Does a CIJ Inkjet Printer Work?
The working principle of a CIJ inkjet printer is based on continuous ink circulation and precise droplet control:
Ink is continuously pumped through a microscopic nozzle to form a steady ink stream.
The ink stream is broken into uniform droplets through controlled vibration.
Selected droplets are electrically charged and precisely deflected by an electrostatic field.
Charged droplets form batch codes, date codes, or expiration dates on the product surface, while unused ink is recycled back into the system.
This technology is widely applied in industrial continuous inkjet printers, including CIJ solutions from Meenjet, to ensure stable, high-speed inline printing.
Conclusion
A CIJ inkjet printer is a reliable industrial inkjet coding machine used for fast and accurate batch coding, date coding, and product marking. With its non-contact printing method, strong adaptability, and proven performance in continuous operation, CIJ technology—represented by trusted manufacturers such as Meenjet—remains one of the most widely adopted industrial marking solutions for manufacturers worldwide.
