A piezoelectric ink jet head that includes a polymer film, for example a flex print, located between the piezoelectric element and the reservoirs in the jet body. The film provides an efficient seal for the reservoirs and also positions the electrodes on the side of the piezoelectric element in which motion is effected, which can reduce the magnitude of the drive voltage. This location of the compliant flex print material also can enhance electrical and mechanical isolation between reservoirs, which improves jetting accuracy. The compliance of the polymer also reduces strain on the ink jet head.

Piezoelectric ink jet module with seal

A single-pass print head has multiple orifice plates each serving some but not all of the area to be printed.

Single-pass inkjet printing

A method of manufacturing an ink jet printing module can include forming a piezoelectric element having a stiffened surface.

Ink jet printing module

Low voltage ink jet printing module

A single-pass print head has multiple orifice plates each serving some but not all of the area to be printed. In embodiments, the printhead includes an array of ink jet outlets sufficient to cover a target of a print substrate at a predetermined resolution, and orifice plates, each of the orifice plates having orifices, each of the orifice plates serving some but not all of the area to be printed. The orifices are arranged in a pattern such that adjacent parallel lines on the print medium are served by orifices that have different positions in the array along the direction of the print lines, that are separated by a distance that is at least an order of magnitude greater than the distance between adjacent orifices in a direction perpendicular to the print line direction.
