Measuring Highway Signage Material Using The ColorFlex 45/0

Highway signage material is very optically complex and has gotten progressively more so over the years. The non-uniform characteristics of these materials include: translucency, visible fluorescence and prismatic sparkle.

These three characteristics are not currently addressed adequately in most highway signage specifications. In addition, the x, y tolerance box used in most specifications is dependent on the optical characteristics of the reference instrument(s) used to establish the initial specification, not necessarily taking other types of instruments into account.
