You can specify that a colorant (usually only a spot color) be trapped like a black color. Keep in mind the following rules about ink types:
- Normal inks can be trapped as black if you select the Treat as Black option.
- Other colors trap to opaque inks, as opaque inks are always treated as black.
- A screened ink is only treated as black if you select the Treat as Black option, and its tint is greater than the Black Color Limit setting.
- Transparent or OpaqueIgnored inks are never treated as black.
