PURPOSE:To quickly and easily perform the fitting operation of a carbon printing board by a method in which a photo-sensitive resin material coated on a base plate is exposed to light through a negative film for baking and washed chemically, and the printing board thus treated is wound around a printing cylinder and fixed. CONSTITUTION:A photo-sensitive synthetic resin 3 is coated through an adhesive 2 over the surface of a metal thin base plate 1, a negative film 4 for baking is closely adhered to the resin 3, and the resin 3 is exposed to light. Then, the resin 3 thus treated is washed chemically to obtain a relief printing plate P on which a desired printing pattern is arranged in order in desired numbers. The relief printing plate P is wound around a printing cylinder 5 having a guide groove 6 in the longitudinal direction and a winding shaft 7 inside along the guide groove 6 and fixed. |
