Opacity charts

Opacity chartsalso known as 'hiding power charts' or 'contrast ratio charts', have simple combinations of black and white surfaceswhich are large enough for reflection measurements with wide aperture, and for Visual opacity and colour observations.

The black and white test areas are marked with a clear, impermeable top layer sealedwhich prevents the penetration of applied coatings into the paper.
