Konica Minolta bizhub PRESS C7000 - Manual (Page 139)

Parameter Option Description
CMYK source
profile Enables you to select a CMYK source profile.
CMYK rendering
intent All printers, monitors, and scanners have a gamut or range
of colors that they can output (or view in the case of a
scanner). If a color needs to be output and is outside the
gamut of the output device, it must be mapped or
approximated to some other color that exists within the
gamut. Rendering intent compresses out-of-gamut colors
into the color capability of the press you are using. When
working with ICC profiles, it is important that you select the
rendering intent that best preserves the important aspects
of the image. Each rendering method specifies a CRD for
color conversions.
Provides the following options:
● Auto—Select this option when your file includes
different objects on the same page—for example, a
presentation that includes JPEG pictures, text, and
Excel graphs. A different rendering intent is
automatically applied to each type of object (image, text,
and graphic). If RGB images and CMYK graphic
elements are on the same page, the RGB images will
use the perceptual rendering intent, while the CMYK
graphic elements will use the relative rendering intent.
Note: Preserve pure CMY colors is not affected by this
rendering intent option.
● Relative—This is the default option for CMYK. This
rendering intent maps some closely related colors in the
input color space to the closest possible color in the
output color space. This mapping reduces the number of
colors in the image.
● Absolute—Select this method for representing
"signature" colors (colors that are strongly identified with
a commercial product). Colors that fall inside the output
color space are represented very accurately.
● Saturation—Select this method for artwork and graphs
in presentations. In many cases, this option can be used
for mixed pages that contain both presentation graphics
and photographs.
Note: Select Saturation to achieve smoothness when
you print RGB vector graphics (non image graphics).
● Perceptual—This is the default option for RGB. Select
this method when working with realistic images such as
photographs, including scans and images from stock
photography CDs. All or most colors in the original
images are changed, but the relationship between the
colors does not change.
