Continuous Ink Jet
Continuous Ink Jet technology (or CIJ) works by expelling electrically charged ink droplets from a printhead nozzle and passing them through an electric field.
How A CIJ Works
The jet of ink is broken into drops inside the chamber through a pulse from a piezoelectric crystal. Ink 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 remaining ink.
The droplets, now charged, pass through an electrostatic field between deflector plates, a combination of speed and charge determines the position of the droplet on the product or packaging substrate to form the required digits or code.
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.
CIJ Printing Applications
Our CIJ printers can code onto almost any material, regardless of porosity, size, shape, and texture. Continuous inkjets are mainly used on production lines to print variable information on individual products – such as manufacture and expiry date coding, product identification information, lot or batch number and barcode printing.
A CIJ saves waste, time and money by removing the need for manual marking or preprinted packaging and provides traceability or compliance with increasingly strict legislation in industries such as beverage, food and pharmaceuticals.
