Horizon Imager User’s Manual xxxix
Preface
•
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.
