A test target with three two bar groups was designed around the DIM microfilm standards. It was produced photographically on a litho film. This target v/as used to discover the factors significant in determining small image sizes and spacings in a microfilm. A 16 mm film holder was designed and built to facilitate the microfilm imaging process. Second and third generation images were made using a liquid-gated contact printing prodedure. It was found that the optical image size an the film at the time of exposure, the image generation, and the optical image size and the density interaction were significant factors in determining small image sizes and separations.
