Investigation of resolution loss in contact exposure of transparent electrophotographic films

A study was performed to determine the nature of the effects causing resolution loss in contact exposure Transparent Electrophotographic (TEP) films. Target and TEP film characteristics were varied and resolution was measured under magnification. Results indicated that the factors responsible for resolution loss included the grain structure of the original target, moisture content of the target emulsion, and surface charge of the target. No conclusions could be made for the effect of TEP photoconductor coating thickness
