Adjustments made to the monitor
If you have high quality monitor capable of finely controlling the amount of light allocated to each component of the RGB mix of colours, it is possible to adjust the colours appearing on the screen in such a way as to approximate the printed result. However, normal monitors allow only rough control of brightness and contrast, control which is applied indiscriminately to the entire screen and is not very effective for anything more than rough adjustment of the appearance of whole screen images. We recommend selection of a highly reliable monitor which suffers from as little deviation in the reproduction of colours as possible.
Some software applications allow you to adjust the Gamma value, a value which adjusts the contrast of a colour. One rule of thumb holds that a monitor Gamma value of about 1.4 brings the colours displayed on a monitor into close agreement with the colours displayed on the printed page.
Adjustment of colour from within software applications
When the software application allows adjustment of colour, the appearance of colours on the monitor screen can be adjusted after comparison with printed results.
Normally, colours are adjusted according to the procedure outlined below. For further information about how to adjust colours, see the documentation accompanying your software application.
•First, print out a colour sample using the CMYK method, and adjust the colours appearing on the monitor screen as you compare them to the printed result. This process is called colour calibration. By performing this calibration, it is possible to bring the colours displayed on the monitor screen and on the printed page into closer match.
•If your software application uses a colour palette to set colour levels, it is possible to finely tune the appearance of a particular colour by adjusting the colour palette.
•If your software application permits you to adjust the colours over the entire screen through use of a colour balance, you can make adjustments like washing out red colours or strengthening yellows over the entire screen at a single stroke.
