Romana| Drop on Demand Technology Drop on Demand Domino products using this technology include K-Series and C-Series. Piezo technology is used to print onto a variety of substrates including plastic cards, glossy and porous stocks. Piezo Drop on Demand (DOD) - high resolution How it works Domino's K-Series printer applies Piezo shared-wall technology to print on a wide range of substrates using UV-curable ink. Oil and solvent inks available on request. The print head of the K-Series contains 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, barcodes, graphics and variable data on to a variety of materials including plastic cards, glossy and porous stocks. |
