Key Benefits

  • Can print on almost any materials – at most speeds, and downward, side on or from underneath / and in any orientation
  • Good printing tolerance – even when surfaces are not flat or still (eg. wobbling bottles), and are 10mm or more away from the printhead
  • Relatively low capital costs
  • Range of inks available, including low evaporation, low taint, and a wide spectrum of colours
Technology Overview

Continuous Inkjet systems (CIJ) work by expelling electrically charged ink droplets from a printhead nozzle and passing them through an electric field.


Inside the chamber, the ink is pulsed by the effect of a piezoelectric crystal causing the ink jet to break up into drops.

A charge electrode charges the individual ink drops that are required for printing as they break off from the ink jet. Those that are not needed are re-circulated.

The charged droplets pass through an electrostatic field between the deflector plates. The combination of the speed and charge in the drops determines the drop is positioned correctly on the substrate

Each ink droplet is tiny - just half the diameter of a human hair – and up to 120,000 of them are expelled every second. Because it’s a non-contact printing method, continuous inkjet is versatile. It can print on most materials, regardless of porosity, size, shape or texture. What’s more, its solvent-based ink dries instantly; so continuous ink systems are perfect for printing onto products as they move along the production lines. For example when beverage marking.

Continuous inkjet is used mainly to print variable information on individual products – such as dates, times, specific text, batch codes, product names and logos. This is particularly useful for providing traceability data and for complying with increasingly strict industry legislation.
