(v13) BackdropAutoSeparations

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

As described in (v13) Named colors in transparency groups, named colors are normally composited independently of process colorants; they are then converted to the output device as a last step after compositing has been performed.

In rare circumstances, it is desirable to convert named colors early during interpretation to the blend space of the current transparency group. Possible reasons for use include: a large number of named colorants in the job, or an application that intended named colors to be converted before compositing. After conversion, all compositing will be done exclusively in the blend space. The configuration setting is:

<< /BackdropAutoSeparations false >> setpagedevice

where the default value is true.

Named color interception (v13) Named color management is performed when converting the named colors to process.

Device colorants are not affected; they continue to be rendered on the device regardless of the setting.
