How to do it

There are several ways to improve the accuracy of the preview. Most involve software that sends a series of (known) colour samples to the screen. A device, either a colorimeter or a spectrophotometer, is attached to the screen and reads the colours as they are displayed. From this data a profile can be made that reflects the state of the screen and can be used to modify the way colours are displayed.

To improve the quality and effectiveness of the process another step called ‘pre-calibration’ can be added. This is most effective where individual control of the red, green and blue colour guns in the monitor is available.

Here are the options for calibration and profiling of your monitor:

Downside

Use Apple Display Calibrator or Adobe Gamma or similar program
Rating:

• Works on the premise that if we visually balance the red, green and blue values of the monitor we’ll get accurate colour – better than nothing.
• Costs nothing to try it.

Everyone views colour differently, so there is no guarantee of match between monitors or monitor to print.
