| Résumé : |
The measurement and control of surface appearance is important to a wide range of industries as the appeal of finished goods can depend strongly on the visual appearance of their surfaces. Many techniques are employed to quantify the appearances of surfaces, measuring properties such a haze, colour, specular gloss or distinctness of image. Specular gloss can be defined as the proportion of light reflected from a standard surface. This measurement is relatively straight forward to make and standard methods for measuring gloss have been developed for use in industries such as paper manufacture, paints and coatings, metals and plastics. Many manufacturers make fixed angle reflectometer instruments (known as gloss meters) which conform to these standards.
Different measurement procedures are required when measuring curved surfaces. Gloss meter manufacturers have developed meters with reduced illumination areas to imrove the measurement of curved surface gloss. The work in the present paper addresses the measurement of the gloss of cylindrical surfaces. Such surfaces have curvatures simply defined by the cylinder radius and readily identifiable axes of symmetry. Measurements were made of the gloss of cylindrical surfaces to assess the performance of gloss meters. Simple models to calculate the expected performance of meters on the cylindrical surfaces are discussed. |
