ABSTRACT:
A printing resin plate is produced by adoption of such process and apparatus that a negative film is placed on a transparent plate positioned on a frame stand; a liquid photopolymerizable resin is applied through a cover film onto said negative film to form a layer; the frame stand and/or a means having a belt, which has been extended between at least two rolls and which can rotate synchronously with the frame stand, are moved to insert a support into a space between the liquid photopolymerizable resin layer on the frame stand and the lower surface of said belt; the frame stand is moved to below the lower surface of the belt while pressing the support with the lower surface of the belt by the downward pressure of the belt thereby closely adhering the support onto the liquid photopolymerizable resin layer; and then the liquid photopolymerizable resin layer is exposed to light.
