Using target groups
Each target group has an identification (ID) number from 1 through 127, which is used
to match the target group with one or more corresponding source groups.
The cmt utility generates pairs of sources and targets, then assigns increasing, sequential IDs to each pair.
You must classify each target group as one of these output color spaces:
- RGB
- CMYK
- Highlight
- CIELAB
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 your printer supports.
