Abstract
Three electrophotographic films from James Rivers Graphics, Eastman Kodak, and Coulter Information Systems were evaluated for application to high performance data recording. An evaluation breadboard, designed to provide basic characterization of image quality and image stability parameters, included the recommended processing stations for each film supplied by the film manufacturers for high resolution toner particle deposition. The results of the sensitometric, holographic, and microimage investigations are presented. The sensitometric evaluation discusses the D log E curves, Dmin, Dmax, and contrast, the effects of processing on sensitometric properties, and high intensity reciprocity law failure. Covered in the holographic evaluation are discussions on diffraction efficiency of Fresnel holograms, latent image decay, image stability to temperature and relative humidity as well as extended and high intensity readout. The microimage evaluation section discusses RMS granularity and contact printing.
