Having a calibrated monitor is one of the essential requirements in a colour managed workflow. With a calibrated monitor you can be confident that the colours you are seeing and editing on screen will accurately match the output of your prints (printer profiling also necessary). If you profile your monitor against a standard you can also be assured that other users with monitors profiled against the same standard will be viewing your images with the same colours.
Calibration of a monitor involves adjusting a monitor’s settings to configure it into an optimal state and then producing and implementing a colour profile which allows the monitor to display colours as accurately as possible. This process should be repeated on a regular basis as the colour accuracy of a monitor changes over its lifetime.
This report details the results of monitor calibrations performed on an Eizo SX2462W monitor on workstation 4 in the digital darkroom and an IMac home computer. The calibrations were carried out using an X-Rite i1Display Pro calibration device and i1Profiler software.

As can be seen in the table above, the white point was closely matched to the target value of 6500K by both monitors but the luminance was slightly lower. Overall the displays are achieving a very close output to the requested industry standard.
The comparison of the profiles to the Adobe RGB colour revealed the limitations of the monitors and shift in available colours. I was surprised to find that the IMac display had a very similar profile to the Eizo.
