ABSTRACT:
Retroreflective sheeting and articles are formed in which the size of the retroreflective and non-retroreflective surfaces may be varied across an array of microprisms. This is accomplished by varying the location of the reflective coating applied to the microprism side facets, such that, some prism side facets are completely coated with reflective material while others are coated only at the apex area; and still others are coated with a non-reflective coatings, such as, a colored adhesive.
