COLOUR PRINTING
The printer drivers supplied with your printer provide several controls
for changing the colour 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 colour 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 colour management functions.
FACTORS THAT AFFECT THE APPEARANCE OF PRINTS
If you wish to manually adjust the colour settings in your printer
driver, please be aware that colour 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 colours
a monitor or printer can reproduce
>
Neither a printer nor a monitor is capable of reproducing the
full range of colours visible to the human eye. Each device is
restricted to a certain range of colours. In addition to this, a
printer cannot reproduce all of the colours displayed on a
monitor, and vice versa.
>
Both devices use very different technologies to represent
colour. 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 colours such as intense reds
and blues and these cannot be easily produced on any printer
using toner or ink. Similarly, there are certain colours, (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
colours do not match the colours displayed on screen.
