Continuous Ink Jet (Small Character)

Domino is the undisputed industry leader in continuous ink jet printers (CIJ) and has set the industry standard for print quality and versatility. Domino is the preferred supplier of many OEMs and MNCs, with the A-Series now selling into over 120 countries.

Continuous ink jet technology uses electrically charged ink droplets to create high quality characters based on a grid formation. Using a wide range of inks that have been developed for specific industry applications, the A-Series can print text, graphics and variable data directly onto food, glass, plastic, metal, rubber and other substrates.

How it Works

The A-Series print head contains an ink drop-generator with a vibrating drive rod. This creates ultrasonic pressure waves in the ink, breaking up the stream of ink into individual droplets. When this stream of droplets falls between a set of electrodes, individual droplets are intermittently charged. The size of the charge given to each droplet determines how far it will be deflected out of the stream when passing through the deflector plates and therefore it's placement on the product.

By placing a collection of these droplets close together, a variety of characters are printed as the product passes the print head. Droplets not deflected out of the stream are re-circulated to repeat the process.

Key Benefits

• Automatic self-cleaning print head guarantees print nozzle stays unobstructed, even on frequent start-stop production lines
• Superior print head technology provides better drop placement and print quality
• High speed printing that keeps up with the fastest production environments
• Non-contact printing enables uneven and flexible surfaces to be coded
