Working with Color
66
Color rendering dictionaries (CRDs) are used to perform color conversions
on RGB data. The following table describes the CRDs for KX-P8420
software and provides guidelines on when to use each one. Each color
rendering style uses a different gamut mapping method, such as
Photographic or Presentation, designed for a particular kind of color usage.
NOTE:
•
The rendering styles referred to in the table cannot be used when
specifying a target device profile with a color management system such
as ColorSync or ICM.
Rendering style
Best used for
Photographic—Preserves tonal relationships in
images rather than exact colors. This rendering
style maps out-of-gamut RGB colors to printable
colors in a way that retains differences in
lightness. Color accuracy is sacrificed slightly in
favor of presenting color relationships in the way
the human eye perceives them. Photographic
rendering typically gives less saturated output
when printing out-of-gamut RGB colors than
Presentation Color rendering does.
Continuous tone
photographs,
including scans and
images from stock
photography CDs
Presentation—Creates bright saturated colors.
This rendering style does not try to match printed
colors precisely to displayed colors but instead
provides vibrant, dense colors. Photographic
images, however, are treated the same way as by
the Photographic rendering style.

Transparency— Improves the correspondence
between monitor colors and printed color on
transparency paper.
