Black Generation

Black Generation defines the method to generate black for the target color space.

  • Target Profile uses the separation from the target profile
  • UCR, GCR, MinK, MaxK generates a new separation independent from the target profile separation. More information is provided in the Online Help for the Printer Profiling.
  • Preserve Black linearizes the input black value and preserves it. Only CMY will be changed.
  • Preserve Separation preserves the ratio of CMY- and black-composed gray during color conversion.
  • SaveInk replaces CMY colorants with black to save ink. This option needs an separate licence.
  • The option Preserve 0% Black is available if the Preserve Separation mode is selected. It prevents creating a black channel for colors from the source color space that had no black. This is important for keeping overprints.
  • The option Enhance Shadows is available if the Preserve Separation mode is selected. This intelligent black generation option prevents detail losses and low densities in dark color regions.

Note: Specifically when converting between two CMYK color spaces, the Preserve Separation mode for Black Generation is of decisive importance, because it preserves the ratio of CMY- and black-composed gray during color conversion. The Enhance Shadows option should always be activated when you select the Preserve Separation mode.
