Opacity is
measured in a similar way to Shade. However opacity, or hiding power,
as defined by ISO 2814 involves measuring whiteness of a known film
of test material on both a black (less than 5%) and a white (greater
than 75%, less than 85%) substrate. A full range of Opacity
Test Charts are available.
