Panasonic KX-P8420 Manuale Utente
1.KX-P8420 Color feature
The KX-P8420 uses a simple and flexible color architecture that produces excellent color results with default settings.
It also allows you to customize your color results using various color controls.
Settings for the following KX-P8420 options can be specified via print dialog box options when you send a job.
This document describes how these options work on the color quality.
Color rendering Dictionaries(CRD)
Before an RGB image can be printed, the file color data must be converted to the printer CMYK color space.
Color rendering dictionaries (CRDs) are used to perform color conversions on RGB color space to CMYK color
space. 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.
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.

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 similar way as by the Photographic rendering
style.
