Abstract
An apparatus for exposure of a relief precursor (P) which comprises a substrate layer and at least one photosensitive layer. The apparatus includes a carrying structure for carrying a relief precursor and an LED array configured to illuminate a photosensitive layer of the relief precursor carried by the carrying structure. The LED array is configured to illuminate simultaneously a predetermined surface area of at least 900 cm. The LED array includes a plurality of subsets of one or more LEDs, each subset being individually controllable. The apparatus also includes a control unit to control the plurality of subsets individually, and such that an irradiation intensity difference in the predetermined surface area is within a predetermined range.
