: Output profiles define the characteristics of your printer. An
ICC profile is made for each ink/media combination that is available for
a device. From the drop-down list you can choose the profile that is
appropriate for your job.

ITMAP RENDERING INTENT
: is the method used to transform the colors in
your design into CMYK colors so that they can be printed. PhotoPRINT
Server comes with these popular rendering intents:
# Perceptual: This intent is best for photographic images. The
relationship between colors in the original is scaled
proportionally to fit the output device's color gamut.
# Relative Colorimetric: This intent is for images, such as
logos, where the original needs to mathematically match the
output. Colors that fall outside the output device's gamut
are converted to colors at the edge of the gamut. This may
reduce the total number of colors available. For this reason,
this intent should only be used when there are relatively few
colors in an image.
#
Absolute Colorimetric works well for colors that must be
matched as closely as possible. Unlike Relative Colorimetric,
colors that fall outside the color gamut are included, but
relocated relative to other colors.
These two rendering intents (Relative and Absolute Colorimetric) are not
proven useful for outputting to digital printers.
#
- Saturation: This intent is best for graphic images, such as
vector art, where true color matching is not as important as
vivid colors. Colors outside of the output device's gamut are
mapped to colors at the extent of the gamut’s saturation.
Colors within the output devices gamut are shifted closer to
the gamut’s saturation extent. This intent may also be used
to boost colors within a photographic image.
# - Spot: This intent is best for use with vector images and
many PANTONE colors. This intent, which produces the
greatest saturation possible, should only be used with non-
photographic images.
There are often choices that need to be made to determine the appropriate
rendering intent for the job you are printing. Sometimes compromises need
to be made between the importance of bitmap and vector elements in order
to determine which intent will produce the best overall appearance.
When jobs mix elements of bitmap and vector there is not always a clear-
cut choice of the best rendering intent. It will probably be necessary to
carry out some tests to determine which looks best. Often it’s best to
sacrifice vector saturation for the bitmap picture elements and choose the
perceptual rendering intent.
