FACTORS THAT AFFECT COLOR PRINTING
The PCL and PostScript printer drivers supplied with your printer
provide several controls for changing the color output. For general
use the default driver settings 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.
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, 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.
