Separating colors in a .tiff file

Only CMYK output is possible using ArcMap for color separation. If your map includes raster images, they should be removed before separation.

Maps can be exported to 1-bit TIFF format, color-separated files based on the unique list of colors defined in symbols that appear in the data frame and page layout. For more information on styles and choosing colors, see ArcMap help.

The TIFF Color Separator is used to color separate a map sheet. The color separator has various options that can be set prior to separating the map sheet, such as the choice of colors to separate, the file format, and the resolution of the TIFF files.

For each color listed in the Plate Definition list, there are two options: include the color in the separation process or a color overprints colors and symbols beneath it in the draw order. The first option is triggered by selecting and unselecting specific colors. The second option is controlled by the Overprint check box in the Plate Definition window. If the Overprint option is not selected, then that color will print over all the symbols and colors drawn underneath it in the map sheet. If the Overprint check box is checked, then the color will not print over symbols or colors drawn underneath it on the map sheet.

The defined colors and their parameters can be set up and exported to an ECT file. This ECT file can then be loaded by any system using the TIFF Color Separator. In this way, a color definition file can be set up for different production workflows. This color file can then be distributed for use during the color separation process. Tools for loading and saving color files help with this process.
