A method and system for automated production of stereoscopic and animated images and hardcopies can utilize a light-sensitive lenticular material employing a conventional or non-conventional photographic emulsion or an instant-developing material. An automated printer can produce autostereoscopic and animated hardcopies in multiple formats from digital and non-digital sources, including single images, stereopairs, and multiple-image sets of negatives, transparencies, or prints. The printer, which includes a projection device and a material plate that can rotate around two perpendicular axes, can utilize software to automate viewing angle calculation, printer control, multiple-image alignment, distortion correction, and image processing and conversion. A digital camera can capture stereoscopic and animated images and record them digitally or on photographic film. A non-digital camera can record stereoscopic and animated images directly onto light-sensitive lenticular material employing a conventional or non-conventional photographic emulsion or an instant-developing material. The printer and cameras can utilize autostereoscopic monitors to preview parallax.

A marking tape for transferring information written thereon to a film when the film is exposed to x-rays. The tape is a laminate of an upper film, a radiopaque emulsion, and a lower film. The top surface of the upper film is partially coated with a writable ink, and the ink coating positioned directly over the radiopaque emulsion. Pressure exerted by the user while writing on the ink surface causes the underlying emulsion to part. When the marking tape is affixed to a film cassette, x-rays penetrate the marking tape in those areas where the emulsion has been parted, the underlying film is exposed, and the information entered on the marking tape is thereby transferred to the film. The marking tape can be made in different sizes and radiopacities that can be distinguished by color-coding the writable surface.

The invention relates to device and method for processing a polymer film surface microstructure based on roll-to-roll hot rolling. The method comprises the following six steps: unrolling, pre-heating, hot-rolling, conforming, cooling and rolling. The unrolling step includes continuously drawing a polymer film from a rolled material and removing static electricity on the surface of the film. After the pre-heating step, the polymer film is heated to a temperature below the glass transition temperature thereof to get ready for the hot-rolling step. The local heating treatment is conducted on a plate roller to allow only the temperature of the stamping surface to rise above the glass transition temperature, so as to roll-form the preheated film. The conforming step enables the rolled film in close contact with the surface of the plate roller, so that the film is completely deformed. The formed film is subjected to both cooling and conforming to cause rapid curing of the surface microstructure and reduce rebound. Compared with the prior art, the device and method have the advantages of reducing the risk of rebound and deformation, improving the forming precision of the microstructure, making demoulding easier and increasing the processing efficiency.
