SeparationPolarity
Type: Enum
How a single-ink separation maps to grayscale (positive = ink dark, the plate-preview look)
Values
| Value | Description | Deprecated |
|---|---|---|
NEGATIVE | Ink renders as luminance: more ink is brighter, and full ink is white. The raw ink-amount signal, matching the contone plate files a RIP consumes. | |
POSITIVE | Ink renders dark: more ink is darker, and full ink is black on white. Matches Acrobat's Output Preview and the positive-film convention, so it is the intuitive plate preview. |
