Color Printing
The printer drivers supplied with your printer provide several 
controls for changing the color output. For general use the 
automatic 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.
Factors that affect the appearance of prints
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.
Differences between the range of colors a monitor or 
printer can reproduce
>
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.
