Piezo Drop on Demand (DOD)
How Piezo works
Domino's K-Series , C-Series and C-Series plus printers apply Piezo shared-wall technology to print on a wide range of substrates using UV-curable ink. Oil and solvent inks available on request. The printheads of these printers contain a series of chambers that are filled with ink. By applying voltages to the walls of these chambers, a distortion is caused that bows the walls outwards. This distortion causes the ink pressure to drop, drawing more ink into the chamber. When the voltage is released and the walls return to their original positions, an ink droplet is expelled through each selected print nozzle.
Collectively these droplets create high-resolution text, bar codes, graphics and variable data on to a variety of porous materials including corrugated outer cases, sacks and wood, and a variety of materials including Plastic Cards , glossy and porous stocks.
The benefits of Piezo printing as opposed to other methods include:
Cost-effectiveness when compared to using labels, providing significant savings (typically ranging from 30% to 80%)
Increased printing flexibility, enabling ad-hoc printing runs and personalisation of packaging
The ability to print onto blank cases. This minimises variants in inventory and simplifies stock planning
Superior print quality and high speed, which is achieved through 500 nozzles printing up to 300dpi
Capable of printing UCC/EAN-128 and ITF-14 compliant barcodes
Non-contact printing ensures package protection
