Continous Ink Jet (CIJ)
Continuous Ink Jet (CIJ) systems work by expelling electrically charged ink droplets from a printhead nozzle and passing them through an electric field.
The ink jet is broken into drops inside the chamber through a pulse from the piezoelectric crystal. Droplets that are required for printing are charged by an electrode as they break off from the ink jet, and the printer re-circulates the rest.
The droplets, now charged, pass through an electrostatic field between deflector plates, a combination of speed and charge determines the correct position of the droplet on the substrate.
Up to 120,000 of these tiny droplets – half the diameter of a human hair - are expelled every second, and this is done without contact to the material being printed on.
Our CIJ printers can code onto most materials, regardless of porosity, size, shape and texture. They are used mainly to print variable information on individual products - such as dates, times, specific text, batch codes, product names and logos - and are particularly useful for providing traceability data and for complying with increasingly strict industry legislation.
