适用范围：Provides a measure of diffuse opacity (paper backing) of white and near-white papers, previously known as 'printing opacity.' The method may be employed for colored papers on condition that their reflectance (paper backing) is greater than 20% and their diffuse opacity (paper backing) is greater than 45%. The method is not suitable for highly transparent papers such as glassine.
