| titleOfInvention | Raised zone retroreflective cube corner article and method of manufacture |
| abstract | A cube corner article and method of manufacturing the article from a series of unitary substrates. The method of manufacture comprises the first step of providing an initial non-unitary cube corner element array comprising a plurality of geometric structures including cube corner elements (212, 218). Then, a replica of the cube corner element array is produced as a substrate suitable for forming retroreflective surfaces. Portions of the replica substrate material are removed. The removal of these portions forms at least one cavity (206) bounded by side walls in the replica at a depth at least that of the cube corner elements. The replica is replicated to produce an additional directly machinable substrate suitable for forming retroreflective surfaces. The substrate comprises at least one raised section (208) having sidewalls at a height at least that of the cube corner elements. At least one raised section is directly machined to form a zone comprising a plurality of geometric structures including cube corner elements bounded by at least two sets of parallel grooves. |
