The world-leading A-Series SureStart print head contains an ink drop-generator with a vibrating drive rod.
This creates ultrasonic pressure waves in the inkjet ink, breaking it up into individual droplets. When these droplets fall 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. This determines 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 allowing many millions of characters to be printed from a litre of ink.
Domino Continuous Inkjet (CIJ) printers can print easy to read text and graphics to enable product identification on substrates from food, glass and plastic to metal and rubber. They offer a wide range of benefits:
High speed printing that keeps up with the fastest production environments
Non-contact printing that enables uneven and flexible surfaces to be coded
Superior print head technology provides better drop placement and print quality
Automatic self-cleaning print head. This guarantees that the print nozzle stays unobstructed, even on frequent start-stop production lines
