Abstract
Embodiments of a system and a method for determining a surface smoothness of a facing specimen can be used in connection with the manufacture of products, including cementitious products such as gypsum wallboard, for example. Such systems and methods can be used to generate a composite smoothness factor based upon a measured mottle value and topography value using stochastic frequency distribution analysis.
