The report presents the results of the engineer design tests of the prototype lithographic enlargina platemaking equipment. The unit represents for the first time the ability to expose 25 12- by 36-inch conventional diazo presensitized lithographic plates directly to miniaturized material, and it therefore reflects a major breakthrough in U.V. optics. The resulting press plates were successfully processed and printed on an offset lithographic press with excellent results. Author
