Abstract
A workpiece 70 is set to holding rotating means and then liquid-state photosensitive resin 10 is supplied to a resin applying smoothing unit 150 to mold the workpiece 70 into a uniform thickness while rotating the workpiece 70 and applying the liquid-state photosensitive resin 10 to the outer periphery of the workpiece 70 by the resin applying smoothing unit 150. Moreover, while rotating the workpiece 70, liquid-state photosensitive resin, it is exposed by high-intensity ultraviolet light 30 and thereby, the surface of the photo-cured photosensitive resin is shaped to remove an unnecessary resin layer. Then, laser carving is performed by an infrared laser beam 40 to perform post-treatment.
Claims19
A method for manufacturing a relief material for seamless printing using a liquid-state photosensitive resin, the method comprising:
- setting a workpiece using either of a printing cylinder or a printing sleeve, which is integrally supported by a metallic mandrel, to a holding and rotating device for holding and rotating the workpiece;
- supplying a liquid-state photosensitive resin having a viscosity that retains an applied shape without being influenced by gravity or centrifugal force due to rotation, to a resin receiving plate which has an angle of inclination and whose front end has a doctor blade shape from a resin supplying device in a linear mode by linearly moving the resin supplying device in an axial direction of the workpiece, at least one end of the resin receiving plate in the axial direction having a resin flow preventive movable dam that is linearly movable in the axial direction of the workpiece;
- applying the liquid-state photosensitive resin supplied to the resin receiving plate to an outer periphery of the workpiece at an applied thickness with the front-end of the resin receiving plate while rotating the workpiece;
- and
- exposing high-intensity ultraviolet light to the liquid-state photosensitive resin applied to the outer periphery of the workpiece while rotating the workpiece to form a photosensitive resin cured layer by optically curing the liquid-state photosensitive resin so that it can be carved by an infrared laser beam.
