LightJet is a trademark of Océ Display Graphics Systems, a division of Océ N.V. (the company that acquired Cymbolic Sciences, Inc.) for a process of printing digital images to photographic paper & film, and for the corresponding hardware.Ordinary silver-covered photographic paper is fixed on an internal drum, where three lasers simultaneously expose the paper (or Duratrans) with red, green, and blue light. The print is then processed using traditional photochemical means.Whereas
xerography and
inkjet printing employ a
halftone process to reproduce digital images on paper, LightJet is a true
continuous tone process.
Posterization and banding are therefore absent from LightJet prints.
