Abstract

A method and apparatus for determining the effect-particle orientation in a film or coating are disclosed. The method comprises using opposing directional reflectance measurements, preferably in continuous processes and allows for an on-line evaluation system to provide more specific control over particle orientation, thereby allowing for better color matching between and among various panels or articles.
