System description
The Ultre 5400 is a prepress imagesetter based on a raster scanning mechanism
with a laser light source in the visible red wavelength. The laser diode is modu-
lated by incoming data and is scanned across the media by a spinning 45 degree
mirror. The media movement is synchronized with the scanned laser beam by
the film transport
Light source
Visible red laser diode, emission wavelength 670 nm
Imaging principle
Rotating monogon, Continuous moving transport of photographic material
Imaging width
406 mm (16 inches),
(imaging length dependent on application program)
Maximum screen frequency
