LightJet is a brand of hardware used for photographic printing of digital images to photographic paper and film. LightJet printers are no longer manufactured but are however remanufactured and resold; and their lasers are still manufactured; and there are all parts at service company in Israel.LightJet produces significantly higher-quality results than most common inkjet printers available today. However, performing the task is not as convenient or easy as with inkjet. LightJet requires a developing machine with chemical materials and densitometry equipmentLightJet is a trademark of Océ Display Graphics Systems, a division of Océ N.V. (the company that acquired Cymbolic Sciences, Inc.) In 2010 Océ was acquired by Canon of Japan. The term "LightJet" is often used to generically describe a digitally made chromogenic print. Competing manufactures of equipment include ZBE Chromira and Durst Lambda. They may be used in Minilabs.

đ LightJet in the context of Photographic paper
Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints. When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from fixing and clearing, though latent exposure is also usually present. The light-sensitive layer of the paper is called the emulsion, and functions similarly to photographic film. The most common chemistry used is gelatin silver, but other alternatives have also been used.
The print image is traditionally produced by interposing a photographic negative between the light source and the paper, either by direct contact with a large negative (forming a contact print) or by projecting the shadow of the negative onto the paper (producing an enlargement). The initial light exposure is carefully controlled to produce a grayscale image on the paper with appropriate contrast and gradation. Photographic paper may also be exposed to light using digital printers such as the LightJet, with a camera (to produce a photographic negative), by scanning a modulated light source over the paper, or by placing objects upon it (to produce a photogram).
LightJet in the context of Photographic print
Photographic printing is the process of producing a final image on paper for viewing, using chemically sensitized paper. The paper is exposed to a photographic negative, a positive transparency (or slide), or a digital image file projected using an enlarger or digital exposure unit such as a LightJet or Minilab printer. Alternatively, the negative or transparency may be placed atop the paper and directly exposed, creating a contact print. Digital photographs are commonly printed on plain paper, for example by a color printer, but this is not considered "photographic printing".
Following exposure, the paper is processed to reveal and make permanent the latent image.
