Colour printing (basics) > 20

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.

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.

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.

A print can look very different under different lighting conditions. For example, the colours 

in a print may look different when viewed standing next to a sunlit window, compared to 

how they look under standard office fluorescent lighting.

The driver settings for manual colour can change the appearance of a print. There are 

several options available to help match the printed colours with those displayed on screen.

The brightness and contrast controls on your monitor can change how your document looks 

on-screen. Additionally, your monitor’s colour temperature influences how “warm” or “cool” 

the colours 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.)
