transformed to this color space. The color mapping table allows RGB CMYK, highlight, and CIELAB, but your actual hardware determines your available choices. For example, if your printer supports only highlight color, your target group must use highlight color. You can specify exact values for output colors. For example, if your printer supports three highlight colors, you can specify colors 1, 2, or 3 with coverage and shading percentages that are supported by your printer.

Creating a color mapping table In the procedure described below, we create a color mapping table to print an Advanced Function Presentation (AFP) file that contains pie charts in the color green. For our AFP files, this pie chart appears as a series of horizontal lines. By accessing the chapter on "Graphic primitives and attributes" in the Graphics Objects Content Architecture for Advanced Function Presentation Reference manual, we can see that these horizontal lines are created by a Pattern Output Primitive with a hexadecimal value of '0B'(11). To turn these horizontal lines into a shade of green when using a ColorSpace source group of GOCA to map to a target group value of RGB, make sure that you specify a low value for red (12), a high value for green (252), and a value under 50 for blue (42) to provide a clear contrast. You must do these tasks from the AIX command line: 1. From the usr/lpp/psf/config directory, specify: cp cmt.cfg piel.cfg This copies the Color Mapping Table configuration file into a file you can customize for your own purposes (in this case, pie1.cfg) 2. Specify vi piel.cfg. This lets you edit the configuration file and insert the applicable values to create the appropriate color mapping (whether GOCA to RGB or OCA to CIELAB) table.
