Abstract
Retroreflective sheeting () comprising a retroreflecting layer (), which has an array of retroreflective elements () formed thereon, and a divergence-enhancing layer () which is positioned in front of the retroreflecting layer (). The divergence-enhancing layer () has localized aberration regions () which change the divergence of light traveling therethrough. The placement of the localized aberration regions () relative to the retroreflective elements () broadens the divergence range of the sheeting ().
