Continuous Ink Jet (Small Character)

Domino is the undisputed industry leader in continuous ink jet inks and 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 printers selling in 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 ink jet inks that have been developed for specific industry applications, the A-Series can print text, graphics and variable data, such as product identification directly onto substrates including:

• Food
• Glass
• Plastic
• Metal
• Rubber

How it Works

The A-Series continuous ink jet printers' print head contains an ink drop-generator with a vibrating drive rod. This creates ultrasonic pressure waves in the ink jet ink, breaking it up into individual droplets. When these 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 its 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. Ink droplets not deflected out of the stream are re-circulated to repeat the process. This is a highly efficient use of ink jet ink, and the printing method is ideal for product identification.

Key Benefits

Continuous ink jet printers offer a wide range of benefits for businesses. As well as the ability to print a variety of text and graphics, allowing product identification, these include:

• Automatic self-cleaning print head. This 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 that enables uneven and flexible surfaces to be coded
