CV-20 - Raster Formats and Sources

Learning Objectives: 
  • Explain how color fastness and color consistency are ensured in map production
  • Compare outputs of the same map at various low and high resolutions
  • Differentiate among the various raster map outputs (JPEG, GIF, TIFF) and various vector formats (PDF, Adobe Illustrator Postscript)
  • Compare and contrast the file formats suited to presentation of maps on the Web to those suited to publication in high resolution contexts
  • Compare and contrast the issues that arise for map production using black-and-white and fourcolor process specifications
  • Outline the process for the digital production of offset press printed maps, including reference to feature and color separates, feature and map composites, and resolution
  • Critique typographic integrity in export formats (e.g., some file export processes break type into letters degrading searchability, font processing, and reliability of Raster Image Processing)
  • Prepare a map file for CMYK publication in a book
  • Prepare a map file for RGB presentation on a Web site
  • Discuss the purpose of advanced production methods (e.g., stochastic screening, hexachrome color, color management and device profiles, trapping, overprinting)
