LightJet 5000 
The Lightjet 5000 Wide Format Printer is capable of direct photographic prints up to 48" x 96” in one piece from a digital file onto backlit or reflective display materials. It uses a three laser light source (red, green and blue) to expose light sensitive photographic substrates. Print surfaces include: Glossy photographic paper, Ilfochrome
(a polyester-based, archival-quality media) and Duratrans
(translucent, backlit display material).
The
optimum resolution for the Lightjet 5000 is Between
305 dpi to 406 dpi at final output size; Inkjet and
electrostatic printers, which simulate continuous-tone
with a dot pattern, would need to image at 4000
dpi to achieve the same photographic resolution.
No
other process (optical or digital) can match
the Lightjet 5000 for sharpness, color quality and
image control. By eliminating the intermediate film,
processing and enlargement stages, this
technology provides a number of advantages over conventional
means; Huge, stunning prints without the usual intermediate
steps that degrade image quality.
