Abstract : This study was performed to determine the feasibility of recording cartographic pressplates directly from digital data. The principal technical aspects considered were laser recording technology and pressplate recording materials. The general conclusion was that, with certain qualifications, cartographic quality pressplates can be generated directly from digital data by laser recording with present and emerging technology. The generation of some form of a full color proof directly from digital data was found to be an essential function in any future system. Although there is a high potential for near term development of a full color proofing procedure compatible with direct pressplate recording from a digital data base, this feature merits particular attention in future developmental activities. Similarly, the candidate pressplate materials, while highly promising, must be more thoroughly characterized and compared in a subsequent program phase to establish practical performance levels, quality control, and availability.
