How to calibrate your colour monitor
A monitor calibrator is a light-sensitive device that measures the brightness and colour of a screen. The calibration device plugs into your PC or Mac via a USB cable.
Using special software, it measures your screen and makes adjustments to display colours accurately. Using a calibrator is very easy. You simply place the colorimeter on the surface of your computer’s screen and follow the on-screen prompts.
The software gets your screen to display a range of colours at different levels of brightness and then produces a colour profile to correct any deficiencies.
Your monitor’s profile is a reference file stored on your computer to ensure the screen displays colours accurately. The screen profile plays no further part in the colour management process apart from that.
