Excerpt from Report of Workshop on Advanced Methods and Models for Appearance of Coatings and Coated Objects: National Institute of Standards and Technology, Gaithersburg, MD, May 20, 1996 Current appearance metrology is almost exclusively based on specular and colorimetric measurements. This has led to a host of specialized metrics e.g., at least ten for gloss alone that are useful in monitoring the day-to-day quality of a product, such as determining whether the paper produced today is as shiny as that produced yesterday. However, these metrics are inadequate for many current requirements including 1) describing metallic and pearlescent coatings which change appearance with angle of viewing and angle of illumination, 2) characterizing texture, 3) predicting the appearance of a finished product from the coating constituents, and 4) predicting the appearance of a coating as the product ages. Needs for new or improved characterization procedures, metrics, standards, and tools have been recognized by the industry for some time. This is illustrated by recommendations in a recent report by the Council on Optical Radiation Measurements (corm).1 The recommendations include establishing a national appearance measurement laboratory program at nist that would address a variety of appearance attributes, including gloss, distinctness of image, orange peel, texture, sheen, translucency, and contrast. The Council further recommends that this effort be supported by developing a system of standard reference materials for these and other appearance attributes.
