发明名称 Retroreflective sheeting with controlled cap-Y
摘要 A retroreflective laminate sheeting (56) has a viewing surface having a retroreflective layer (12) which has a first cap-Y value of a viewing surface side thereof. A plurality of discrete pigmented indicia (16) are disposed on the viewing surface side (14) of the retroreflective layer (12). The pigmented indicia (16) define a second cap-Y value of the viewing surface of the sheeting (56), the second cap-Y value being less than the first cap-Y value. One method of making a retroreflective sheeting (56) includes forming a retroreflective layer (12) on a web, the web moving in a web direction. The method includes applying a pigmented material proximate the retroreflective layer (12), the pigmented material forming a plurality of parallel stripes (16) oriented substantially in at least one of the web direction and a direction orthogonal to the web direction.
