Piezoelectric printers are high-resolution inkjet printers that operate on the basis of continuous inkjet technology or the drop-on-demand process.
They utilize the piezoelectric effect: Piezo crystals located behind a print nozzle are subjected to a voltage. The crystals deform, exert pressure on the colored liquid and direct a color droplet through the nozzle. The strength of the pulse controls the size of the droplet.
In coding and marking technology, piezoelectric printers are frequently used for labeling packaging and coding products as well as addressing and personalization in virtually any area where outstanding typographical quality is required.
