(v13) Source space color management
This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.
This feature is rarely used, but may be useful for special effects.
The source space intercepts are used to color manage objects into their transparency group differently to transforms between transparency groups. This is done using the /SourceCMYK, /SourceRGB,
and /SourceGray setinterceptcolorspace
keys. This is a simple example:
<<
/DeviceCMYK [ /ICCBased (iccprofiles/SWOP.icc) (r) file ]
/DeviceRGB [ /ICCBased (iccprofiles/sRGB.icc) (r) file ]
/SourceRGB [ /ICCBased (iccprofiles/probeRGB.icc) (r) file ]
>> setinterceptcolorspace
<<
/Profile (iccprofiles/Digital.icc) (r) file
>> setreproduction
where the example from (v13) Interception re-purposing of jobs for different output devices has been augmented with the /SourceRGB
key. The intention of the example is to highlight RGB objects with a special probeRGB.icc profile that indicates their presence, regardless of the blend space of their parent transparency group.
