Abstract: A film manufacturing method and a device thereof by a resin print configured to allow resin to be temporarily saved at one side of a raw film material for integrally printing by compression force of a roller, wherein the device comprises: a supply roller wound with a raw film material; a printed roller adhesively fed thereon with the raw film material supplied from the supply roller and formed thereon with a plurality of grooves; a supply hopper for supplying a predetermined melted resin toward the surface of the printed roller; and first and second pressing rollers abutted on both sides of the printed roller for pressing the raw film material to the surface of the printed roller, such that a preferable pattern can be printed on the raw film material, resulting in increase of productivity by simplified process and reduction of raw materials.
