Both devices use very different technologies to represent color.
> A monitor uses Red, Green and Blue (RGB) phosphors (or
LCDs).
> A printer uses Cyan, Yellow, Magenta and Black (CMYK)
toner or ink.
Very vivid colors (such as intense reds and blues) can be
displayed on a monitor. These same colors cannot be easily
produced on any printer using toner or ink.
There are certain colors (for example, some yellows), that can be
printed, but cannot be displayed accurately on a monitor.
These differences between monitor colors and printer colors are
the main reasons why printed colors do not always match the
colors displayed on screen.

The brightness and contrast controls on your monitor can change
how your document looks on-screen.
Your monitor color temperature also influences how “warm” or
“cool” the colors look.
Several of the color matching options make reference to your
monitor’s color temperature.
Many monitors allow you to adjust the color temperature through
their control panels.
There are several settings found on a typical monitor:
k=degrees Kelvin, a measurement of temperature
5000k or D50 Warmest, yellowish
lighting
Typically used in graphics arts
environments.
6500k or D65 Cooler Approximates daylight conditions.
9300k Cool The default setting for many monitors
and television sets.
