The All separation and separation omission

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

The handling of jobs containing the /All separation is special and perhaps non-obvious. There are two cases:

• If no colorants apart from All, SuperBlacks objects, or RegisterMarks objects are detected, and a black separation exists, those objects are transferred to the black separation and only black is output. (SuperBlacks and RegisterMarks are defined in Ignore in SeparationDetails.)
• If there are other colors used, and RegisterMarks or SuperBlacks are set, then those classes of object are ignored. Genuine All separations are included in these ignored objects. (To understand this, think of All as a subset or special case of RegisterMarks, which itself is a subset of SuperBlacks if there is a black separation).

The RIP renders SuperBlacks or RegisterMarks objects only in the planes in which they were marked, and does not transfer the objects to the All separation.
