Different color reproduction techniques have different color capabilities, or 

transparency films have comparatively large gamuts, as do color monitors. The color gamut 
that can be produced using process inks or 

 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 Color Server, nor can they be reproduced on a press 
using 

. Moreover, different printers have different gamuts. Some colors your 

printer can produce cannot be reproduced on an offset press, and vice versa. The following 
figure illustrates this concept of differing gamuts.

You must account for the gamut of your printer when designing on a color monitor. When 
printed, colors that fall outside the printer gamut are “mapped” to printable colors. This 
process, referred to as 

, takes place when color data is converted or adjusted 

to meet the gamut requirements of a printer. 

The Color Server 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 you select for a particular print job. For added flexibility, 
you can also use the Color Server color management system in combination with the color 
management systems on Windows and Mac OS computers.
