Preparation of photosensitive resin printing master

Abstract

Abstract PURPOSE:To obtain a photosensitive resin printing master high in master thickness precision, by feeding a liquid photosensitive resin on a substrate to be moved together with an image carrier at an equal speed on 2 roller surfaces disposed in parallel and illuminating the obtained photosensitive resin layer with an active light. CONSTITUTION:Two rollers 1, 2 is disposed at a specified interval, the circumferential wall is made of a material transmitting an active light and provided with active light source 3 in its inside. Image carrier 4 and substrate 5 for photosensitive resin layer are moved along the circumferential surfaces of rollers 1 and 2 in the same direction according to each arrow at the same peripheral speed, respectively, and photosensitive resin fluid 6 is continuously supplied in the proper position of a space between carrier 4 and substrate 5 to form a photosensitive resin layer of thickness similar to the width of the gap on substrate 5. This photosensitive resin layer is illuminated by the active light from the backside of carrier 4 to form hardened areas A and nonhardened areas B corresponding to the image, and the desired printing master is obtained by processing areas A, B in the subsequent developing process.
