ES 1220n Color Printing  • 156

The PCL and Postscript emulation printer drivers supplied with this 
printer provide several controls for changing the color output of your 
printer. For general use the Auto settings will suffice, providing 
reasonable default settings that will produce good results for most 
documents.

Many applications have their own color settings, and these may 
override the settings in the printer driver. Please refer to the 
documentation for your software application for details on how that 
particular program’s color management functions.

If you wish to manually adjust the color settings in your printer driver, 
please be aware that color reproduction is a complex topic, and there 
are many factors to take into consideration. Some of the most 
important factors are listed below.

• Neither a printer nor a monitor is capable of reproducing the full 

range of colors visible to the human eye. Each device is restricted 
to a certain range of colors. In addition to this, a printer cannot 
reproduce all of the colors displayed on a monitor, and vice versa.

• Both devices use very different technologies to represent color. A 

monitor uses Red, Green and Blue (RGB) phosphors (or LCDs), a 
printer uses Cyan, Magenta, Yellow and Black (CMYK) toner or 
ink.

• A monitor can display very vivid colors such as intense reds and 

blues and these cannot be easily produced on any printer using 
toner or ink. Similarly, there are certain colors, (some yellows for 
example), that can be printed, but cannot be displayed accurately 
on a monitor. This disparity between monitors and printers is often 
the main reason that printed colors do not match the colors 
displayed on screen.
