Abstract: A printed reflective sheet manufactured using open-type beads and, more specifically, a printed reflective sheet comprising: a base sheet; an adhesive layer formed on the base sheet; a reflective film which is formed on the adhesive layer and has reflective beads protrusively embedded therein; an ink-fixing layer formed on the reflective film and on the protruding portions of the reflective beads; a printed layer formed on the ink-fixing layer; and a transparent protective layer formed on the printed layer, wherein the ink-fixing layer, printed layer, and transparent protective layer are formed in a curved structure corresponding to the protruding portions of the reflective beads. Accordingly, the open-type printed reflective sheet has not only high reflective brightness but also excellent recognizability of a printed image.
