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.

Abstract: A method and a medium for laser imaging is herein disclosed. The medium incorporates one or more types of microstructures having a predetermined heat or radiation modifiable optical characteristic such as color, scattering, diffusion, diffraction, interference and iridescence. Associated intimately with the microstructures is a radiation antenna that acts to absorb radiation from a radiation source. The radiation antenna and source are attuned to one another to efficiently transfer energy therebetween and subsequently to the microstructures; this transfer of energy results in the modification of an optical characteristic of the microstructures to form an image on the medium. The medium has one or more layers that may include both the radiation antenna and the microstructures. Alternatively, the microstructures and radiation antenna may be included in separate layers. Coatings that incorporate one or more layers that include distinct microstructures and radiation antennae are also contemplated.
