Color Printing Basics; Factors That Affect The Appearance Of Prints - Toshiba e-STUDIO222CS Printing Manual

OLOR 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.

ACTORS 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.
Viewing conditions
A print can look very different under different lighting conditions. For example, the colors
in a print may look different when viewed standing next to a sunlit window, compared to
how they look under standard office fluorescent lighting.
Printer driver color settings
The driver settings for manual color can change the appearance of a print. There are
several options available to help match the printed colors with those displayed on screen.
Monitor settings
The brightness and contrast controls on your monitor can change how your document looks
on-screen. Additionally, your monitor's color temperature influences how "warm" or "cool"
the colors look.
There are several settings found on a typical monitor:
> 5000k Warmest; yellowish lighting, typically used in graphic art environments.
> 6500k Cooler; approximates daylight conditions.
> 9300k Cool; the default setting for many monitors and television sets.
(k = degrees Kelvin, a measurement of temperature.)
