Patent ID: 7709183

Claim:
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.
