Why is it important to calibrate my monitor? How do I do this?
Profiling and Calibrating FAQ's -
It is important to calibrate the monitor you are using as quite often the screen will be much brighter than what is achievable from the printer and is set to whatever default colour it is shipped with. Proper calibration will ensure that the colours and black levels remain true.
There will always be a difference between what you are seeing on the screen and what is being produced on print as one is projected light and one is reflected light. However using an ICC profile along with a calibrated screen will significantly reduce the difference between the two and help to get the results produced from the printer as close as possible to what you are seeing on screen.
NB: It is important to remember that even after calibrating your screen, you may still need to further adjust the brightness on the monitor.
You can calibrate your monitor using appliances such as a Spyder calibrator.
