The application of the four-color process to printing fine line work found on topographical maps was investigated. A description of the mapping process is included and the reason why the four-color process would be advantageous to cartographic printing was discussed. The chapter on fourcolor process theory was included for the benefit of the cartographic community - The experimental design for data transfer, color tolerance, target design to match spot and process color, as well as color space employed, were reviewed. The reasons for the use of a direct digital proofing system were explained. The results of data transfer were evaluated and solutions obtained for limitations in the transfer mechanisms. Color tolerances were established using the CIE LAB color space and two image maps. Using colorimetry, test targets matching the spot color to its equivalent process color were evaluated and found to fall within the established tolerances . Three topographical maps were produced totally in the digital domain. The Cartographic Community carefully evaluated these products and deemed them as the preferred method for generating topographic maps . The results of this study can be interpreted to show that the four-color process system is the most advantageous method for the generation of cartographic products.
