PRINTING

ASICS

)

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.

ACTORS

THAT

THE

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.
