An ink-jet print head suitable for use with pigment based inks having protective layers interdisposed between pairs of juxtaposed dissimilar metal surfaces having a relatively large electrochemical potential difference therebetween so as to substantially reduce the potential difference, thereby reducing clogging of the ink-jet nozzles. The ink-jet head further comprising a composite body formed with an array of ink jet nozzles for respectively emitting a train of ink droplets, each of said ink jet nozzles being associated with a piezoelectric transducer and adapted for flow communication with a source of pigment based ink via an ink duct.
