Black point compensation
The
Black point compensation
option lets you control the output quality of shadow areas for CMYK source
colors.
Use
Black point compensation
to enhance details in shadows when the CMYK source space is larger than the
gamut of the printer. In proofing applications, when the CMYK source space is smaller than the gamut of the
printer, do not use this option.
Note:
For RGB source colors, black point compensation is always applied.
Black point compensation works by scaling the source colors so that the darkest point in the source profile maps
to the darkest point in the output profile.

Color Printing .
Print CMYK gray using black only
The
Print CMYK gray using black only
print option provides settings to print a CMYK grayscale job using black
instead of process black.
This option renders the selected object types (
Text/Graphics
or
Text/Graphics/Images
) in grayscale using K-only
black. (Graphics refer to vector graphics; Images refer to raster images.)
This option is designed to use black efficiently, by using only black (rather than four-color process black). (See
Color Printing ).
Grayscale source
The
Grayscale source
print option defines the source color space for all grayscale objects.
Use Gray embedded profiles
When the
Use Gray embedded profiles
option is selected, the Fiery ES ignores the
Grayscale source
option and
uses the Gray profile embedded in the print job as the Grayscale source profile.
For more information, see
Color Printing .
Grayscale rendering intent
The
Grayscale rendering intent
print option allows you to specify a default CRD (color rendering dictionary) for
color conversion when printing grayscale images, graphics, and text.
Do one of the following:
•
Select
Photographic
to print photographs, including scanned and digital camera images. The result is less
saturated than Presentation style.
•
Select
Presentation
to print files with artwork, graphics, and text. The result is similar to Photographic, with
well-rendered in-gamut colors, such as flesh tones, and more saturated colors.
