    摘要: A platemaking system uses an intermediate imaging mask (10) made of a film of photochromic material (14), preferably bacteriorhodopsin. The film is nominally opaque, but is temporarily made transparent by exposure to light of a certain wavelength. An image is formed on the mask using light (18) of the appropriate wavelength, which renders portions of the mask transparent. The mask is then interposed between a photosensitive printing plate (20) and a light source (24) which produces light to which the plate is sensitive, exposing the printing plate and thereby transferring the desired image onto the plate. The described method is preferably implemented using a transparent rotating drum (30) that is coated with a bR film (31). As the drum rotates past a green or yellow laser (34), a desired image (32) is written onto the film by the laser's beam. The drum rotates the image until it is opposite a photosensitive printing plate (36), and a light source (38) inside the drum exposes the plate through the mask to transfer the image. The system preferably includes another light source (44) that is directed onto the formed image after it has been transferred which 'erases' the film and thus prepares it to accept a new image.

    摘要: Photographic process, in which a substrate comprising a plurality of superimposed layers of photochromic materials sensitive to different light wavelengths is provided. The object to be photographed is scanned and a digital file defining the image of the object is generated from the scanning. A plurality of sources of laser light having different wavelengths, each of which is the wavelength to which one of the photochromic materials is sensitive is provided and the layers of photochromic materials are irradiated by means of the laser beams produced by the sources, according to a program determined by the digital file, whereby to develop in each pixel of the substrate the color that it has in the image. The colors thus generated in the pixels of the substrate layers; and the background areas of the substrate layers are set.

    摘要: Disclosed herein is a recording/reproducing method for an optical recording medium comprising a step of heating a recording layer containing a photochromic material and a polymer which are so combined with each other that a photostationary state attained upon irradiation with light of a specific wavelength is varied with temperatures, and a step of applying the light of a specific wavelength to the heated recording layer for bringing the same into a photostationary state and recording information. In order to reproduce the information, a portion of the recording layer which is in a photostationary state is selectively heated, and reproducing light is applied to reproduce recorded and unrecorded states.
