Horizon Imager User’s Manual xxxix
3UHIDFH
Depending on the configuration, the Horizon imager includes a
built-in densitometer. The built-in densitometer is designed to
produce consistent prints by compensating for variation from
one film cassette to another and one imager to another. For
applications that require absolute control of the maximum
density, the results should be checked against a bench-top
commercial densitometer. The internal densitometer can be
calibrated to a desktop unit. See the
Horizon Imager Technical
Manual
for more information.
DirectVista
media is optimized for grayscale prints, while
ChromaVista
is optimized for color prints. If
ChromaVista
is not
giving you satisfactory results with grayscale images, you may
want to consider using
DirectVista
media for those applications.
Media variations between different production lots may produce
subtle differences in image quality and color. These variations
most often occur in color ribbons and are characterized as a
slight color hue in grayscale images.
Codonics film media is designed to be viewed using a light box
suitable for viewing medical diagnostic images.
Codonics paper/white film media is designed to be viewed
under cool-white, fluorescent light. Spectral differences and
intensity variations in the viewing light sources can change the
apparent color of images printed on paper/white film.
Printed images that are subject to prolonged exposure to
sunlight, ultraviolet light, or extreme heat may degrade in image
quality. (For example, printed sheets should not be stored in an
automobile on a sunny day.) Precautions should be used to
avoid prolonged direct exposure.
