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.
Claims11
An apparatus for manufacturing a relief material for seamless printing using a liquid-state photosensitive resin, comprising:
- a workpiece continuous rotating mechanism having a structure capable of rotating a workpiece by integrally connecting the workpiece thereto so as to be able to apply a liquid-state photosensitive resin to an outer periphery of the workpiece;
- a resin supplying mechanism having at least one resin supply nozzle connected with a vessel for housing the liquid-state photosensitive resin and that is linearly moveable in an axial direction of the workpiece;
- a resin applying smoothing mechanism having a resin receiving plate for receiving the liquid-state photosensitive resin from the linearly moveable resin supply nozzle of the resin supplying mechanism and for applying the resin to the outer periphery of the rotating workpiece, the plate having a front end having a doctor blade shape at a position facing the workpiece and having a structure which can move in a direction perpendicular to the axis of the workpiece to adjust a tilt angle of the plate, at least one end of the resin receiving plate in the axial direction having a resin flow preventative moveable dam that is linearly moveable in the axial direction of the workpiece;
- and
- an exposing mechanism capable of applying high-intensity ultraviolet light to liquid-state photosensitive resin applied to the outer periphery of the workpiece to form a photosensitive resin cured layer thereon.
