In the world of industrial printing, Continuous Inkjet (CIJ) printers stand out as versatile and efficient machines. These printers are widely used for marking and coding products in various industries, from food and beverage to pharmaceuticals and electronics. But what exactly is a CIJ printer, and how does it work? Let’s dive in.

The Basics of CIJ Printing

Continuous Inkjet printing is a non-contact printing method that uses electrically charged ink droplets to create text, logos, barcodes, and other markings on a wide range of materials. Unlike other printing technologies, CIJ printers constantly generate a stream of ink droplets, hence the term “continuous.”

Advantages of CIJ Printers

1. Versatility: CIJ printers can print on a wide variety of surfaces, including plastic, glass, metal, and even curved surfaces.
2. High-Speed Printing: They can print at very high speeds, making them ideal for fast-moving production lines.
3. Non-Contact Printing: The printhead doesn’t need to touch the surface, allowing printing on uneven or sensitive surfaces.
4. Durability: CIJ inks are available in various formulations, including fast-drying and solvent-resistant options for harsh environments.
5. Cost-Effective: The ability to recirculate unused ink makes CIJ printers economical for long production runs.

Applications of CIJ Printers

CIJ printers are used across numerous industries for various applications:

• Date coding on food and beverage packaging
• Batch numbering on pharmaceutical products
• Serial numbers on electronic components
• Expiration dates on cosmetics
• Lot codes on industrial parts
