The Spectra Nova JA 256/80 pl AAA printhead is a high performance, robust and reliable jetting assembly designed for a broad range of industrial and commercial printing applications at resolutions up to 450 dpi.
Four electrically independent piezoelectric slices, each with 64 addressable channels, are combined to provide a total of 256 jets. The nozzles are arranged in a single line, at a 0.011 inch distance between nozzles. The fluid interface and electrical connection are at the top of the jetting assembly and several mounting configurations are possible. This jetting assembly contains serial-to-parallel converters for selecting which jets to fire; all jets can be fired simultaneously or individually.

Since 2010 we sell the print heads online worldwide supplying large advertising enterprises and small printing companies.
