ABSTRACT:
The present invention is directed to a method and a system for forming a relief image on a photosensitive printing element. The system comprises an enclosure housing a conveyor and a heatable roller. The photosensitive printing element is positioned on a continuous loop of the conveyor and the heatable roller is urged towards the photosensitive printing element on the conveyor. An absorbent material is conducted over the heatable roller and is used to absorb at least a portion of the liquefied or softened material from the photosensitive printing element when the heatable roller is heated. The system also comprises ventilation means operatively connected to the enclosure for treating and recycling air containing contaminants that are released into the enclosure as the portion of the photosensitive material is heated and then softens. The ventilation means typically include a particulate filter and a bed of adsorbent material. The treated air may then be returned to the enclosure.
