Question

What option do you need to choose for the Preserve Separation Interaction parameter in the Optimize PDF Separations task?

Answer

Change the option of this parameter when the separations you remove contain objects knocking out in other separations.

None:
This only deletes knockout objects that are only defined in the removed separation(s). Use this when removing separations that don't influence the final result (e.g. die cut separations).

Standalone:

This converts knock-out objects that are only defined in the removed separation(s) to white knock-out objects defined in one of the remaining separations. The remaining separations keep looking the same. This method is recommended for most use cases.

For Versioning:

This converts knock-out objects that are only defined in the removed separations to white overprinting objects. Those are defined in a color space made from the remaining separations of the file and overprinting on all other separations. This ensures that when re-adding separation layers for versioning, the final result looks the same as the original file.
