Abstract
The invention relates to a processing apparatus for processing a flexographic plate. The apparatus comprises a supporting unit for supporting a flexographic plate including a relief layer containing a photosensitive material, the plate further including, on the relief layer, a carbon layer that is impenetrable for UV light. The apparatus also comprises an optical system for locally ablating the carbon layer for forming a pattern in the carbon layer that is penetrable for UV light, and for polymerizing at least a top part of the relief layer under the carbon pattern layer. Thereto, the optical system includes a single radiation source for both locally ablating the carbon layer and for polymerizing at least a top part of the relief layer.
