ColorBlackGeneration Enum

How to represent an achromatic (gray/black) RGB-authored color as CMYK - see BlackGeneration.

public enum ColorBlackGeneration

Fields

UseTrueBlack 0

K-only: C=M=Y=0, K scaled to the source gray’s darkness. Default.

UseRichBlack 1

K-only plus proportionally-scaled C/M/Y for ink density on press (common for large solid-black areas, at the cost of registration sensitivity) - only the darkest values get meaningful CMY; lighter grays stay close to neutral.
