PROBLEM TO BE SOLVED: To realize the manufacturing method for an optical information recording medium, with which the development of the molding defect in a printing layer during a single printing process is checked as small as possible and the thicker film thickness of the printing layer is realized and consequently a fine printing can be obtained due to the heightening of the degree of shielding of color in a light reflecting layer, a protective layer of the like and, in addition, the miniaturization of production facilities and the reduction of a production cost are realized. SOLUTION: In a printing process, ink is dripped on a mask 30 having meshes 34 so as to press the mask 30 with a squeegee 32 against the protective layer 108 formed on a board 102 in order to print desired letters or the like on the protective layer 108 so as to form the printed layer 110, the number of the mesh 34 comprising the mask 30 is set to be 150 mesh or more and 250 mesh or less and the viscosity of the ink is set to be 100 P or more and 300 P or less.
