Gives a method to determine the opacity (paper backing) of paper by diffuse reflectance. Restricted to white and near-white papers (and boards), and paper or board that has been with a fluorescent dyestuff or exhibits significant fluorescence can be measured. The agreement between values that are obtained with different instruments may not be satisfactory and there could be difficulty in assessing the results meaning.
