Abstract
A method and an apparatus for fabricating gravure printing cylinders of synthetic resin in which a solution of a photosetting polyamide resin used as a coating resin is applied over the surface of a cylindrical base spirally as successively overlaid layers and thereafter the applied resin in subjected to drying by a heater and to photosetting by irradiation with ultraviolet rays, electron rays or the like. The resin layer surface thus obtained is mechanically engraved by an electronic engraver for forming gravure cells. The irradiation of ultraviolet ray, electron ray, or the like may be effected during or after application of the polyamide resin over the cylindrical base.
