Different color reproduction techniques have different color capabilities, or
gamuts. Color transparency films have comparatively large gamuts, as do
color monitors. The color gamut that can be produced using CMYK toners
on paper is smaller. This is why some colors that can be displayed on a
color monitor, especially bright saturated colors, cannot be reproduced
exactly by your KX-P8420 print device—nor, for that matter, can they be
reproduced on press using process colors. Moreover, different print devices
have different gamuts—some colors that your print device can produce
cannot be reproduced on an offset press, and vice versa. The following
illustration provides a graphical representation of this concept.

You need to account for the gamut of your print device when designing on a
color monitor. When printed, colors that fall outside the print device's gamut
are "mapped" to printable colors. This process, referred to as gamut
mapping, takes place when color data is converted or adjusted to meet the
color space and gamut requirements of a print device.
The KX-P8420 Color Printer is specially designed to perform gamut
mapping at high speed with high quality results. It provides these color
management features automatically, using either built-in default settings or
settings that you specify for a particular print job. For added flexibility, the
KX-P8420 color management system can also be used in combination with
color management systems on Macintosh and Windows computers.
