ABSTRACT A retroreflective laminar sheet assembly comprises base and cover sheets made from flexible synthetic plastic materials, and an array of interposed retroreflective film pieces seated within discrete cells formed therebetween. The sheets and film pieces of different compositions are used to afford a preselected balance of mechanical and optical properties, and the construction is such that distortion is minimized and flexibility of the assembly is maintained. The invention also provides novel methods by which such an assembly can be produced, which may take advantage of inherent or induced cohesive characteristics of the components employed.
