Abstract

Apparatus for exposure of a relief precursor includes a substrate layer and at least one photosensitive layer. The apparatus includes a first light source configured to illuminate a first side of the relief precursor, a movable second light source configured to illuminate a second side of the relief precursor opposite the first side, a movable shield located between the first light source and the second light source and configured to capture at least a portion of the light of the second light source transmitted through the relief precursor, and a moving means configured to move the movable shield simultaneously with the second light source.
