Before an RGB image can be printed, the file’s
color data must be converted to the printer’s
CMYK color space. Color rendering
dictionaries apply optimal gamut mapping
methods to documents that contain text,
photographs and illustrations.
The Photographic CRD optimizes the range of
colors on the printer to produce the best
results for photographic or bitmapped images.
The Presentation CRD optimizes the output of
pure, saturated colors such as those used in
business presentations.
The Transparency CRD improves the
correspondence between monitor colors and
printed color on transparency paper.
For additional information, see “Color
rendering dictionaries” on
page 66
.
NOTE:
• Color rendering dictionaries cannot be used
with CMYK files. Note also that PS Color
Matching must be specified in the Print
dialog box to enable the use of CRDs.

The Adobe PostScript 8.5.1 driver can convert
RGB colors of a file to a specified CMYK
device target using ICC technology. Select this
option to specify the use of an ICC device
profile installed on your computer.
For information on how to install and use the
KX-P8420 ICC printer profile (ColorSync
profile), see “Installing the KX-P8420
ColorSync profile” in the
Setup Manual or
Operating Instructions.
Color Mode
CMYK/CMY/Grayscale
(Default: CMYK)
By default your printer is set to print
documents in color (CMYK).
Select Grayscale to optionally print documents
in grayscale.
Select CMY to print using Cyan, Magenta, and
Yellow toner only. This setting allows you to
print drafts of color images more quickly than
in CMYK mode. The CMY setting is available
only when Resolution is set to 600
×
600 dpi.
When this setting is selected, the default
settings for Color CRD Text, Color CRD
Graphics, and Color CRD Images are used
automatically.
