A process of making a micro glass beaded retro-reflective material comprising micro glass beads lenses, which are partially embedded in graphic matrixes of binding material. The pre-fixed rotating axes of the micro glass beads lenses lie at varying angles to the general plane of the graphic matrix to achieve uniform visibility in broad range of entrance and observation angles. The gaps between the graphic matrixes allow the permeability, flexibility, softness and color of the base material to be maintained.
