Color Print Matching

The install utility provides a color matching profile for your printer. In
general, using these Color Matching settings will provide reasonable
default settings that 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
Printed Documents
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.

Range of Colors: Monitors Versus Printers

• 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.

Viewing conditions

A printed document can look very different under different lighting
conditions. For example, the colors may look different when viewed
