Monitor Adjustment Test Patterns

Many monitors are used with their brightness and contrast controls set too high. This results in an image that looks correct on screen but does not closely match the colors that will print. Calibrating your display sets the brightness and contrast controls so that you see the most detail possible in the dark shadows and bright highlights of your images. You should calibrate your display any time you change your computer monitor or the lighting around your computer. To make images on screen look more like they will look when printed:
  1. Turn the brightness and contrast controls on your computer all the way up.
  2. Adjust the brightness until the 2 darkest black patches can not be distinguished.
  3. Adjust the contrast so the monitor is comfortably bright.
Basically, adjust contrast and brightness for best gray and color scales.
