ABSTRACT:
Method and apparatus for manufacturing a seamless printing roll. A liquid photosensitive resin is applied to the space between a process cylinder and a rigid plate which is transparent to actinic light. Relative movement is provided between the cylinder and the plate perpendicular to the longitudinal axis of the cylinder, while the cylinder is rotated in synchronization with the relative movement of the rigid plate to evenly spread the photosensitive resin. The photo-sensitive resin is simultaneously exposed in the space between the cylinder and rigid plate.
