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.
