Parameter Option Description
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 printer 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,
