Each target group must be classified as a color space that is the kind of color you want as output. The color spaces defined in the matching source groups are 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 reviewing the chapter on "Graphic primitives and attributes" in Graphics Objects Content Architecture for Advanced Function Presentation Reference, 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 Windows command line: 1. From the install_path\config directory, specify: copy 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 notepad 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. See the sample cmt.cfg configuration file below Required, starts a Color Mapping Definition. # One definition for each Source to Target mapping BeginSourceDef: # Required, starts the Source Parameters BeginSourceDef ColorSpace: # Required, values= OCA | Highlight | GOCA Chapter 28.

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
reviewing the chapter on "Graphic primitives and attributes" in
Graphics Objects
Content Architecture for Advanced Function Presentation Reference
, 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 Windows command line:
1.
From the
install_path\config
directory, specify:
copy 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
notepad 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. See the sample
cmt.cfg
configuration file below:
# -------------------------------------------------------
# Required, starts
a Color Mapping Definition.
# One definition for each Source to Target mapping.
# -------------------------------------------------------
# -------------------------------------------------------
# BeginSourceDef:
# Required, starts the Source Parameters
# -------------------------------------------------------
BeginSourceDef:
# -------------------------------------------------------
# ColorSpace:
# Required, values= OCA | Highlight |
GOCA
