ABSTRACT:
The invention is directed to methods of making an article bearing a relief image using a removable film. First, an imageable film that contains at least a mask substrate and an imageable material is imagewise exposed to imaging radiation to form an imaged film. The imaged film is then transferred to an imageable article, such as a flexographic printing plate precursor. The resulting assembly is exposed to curing radiation resulting in exposed and unexposed areas of photosensitive material on the imageable article. Following exposure to curing radiation, the imaged film is then removed from the imageable article. The imageable article is then developed with a suitable developer to form a relief image. The imaged film may then be reused to make additional articles bearing the relief image.
