Simple interception of device color spaces

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

The next easiest and common workflow is where the graphic designer has designed a page, for example for SWOP, but which may also contain RGB images. This workflow is best handled by passing colors in /DeviceCMYK and /DeviceGray straight through to the SWOP device without modification.

/DeviceRGB objects are treated as though they were painted in an /ICCBased color space. This example configuration, as shown in Figure: Simple interception for conventional press, transforms /DeviceRGB using an sRGB.icc /SWOP.icc profile pair:

  /DeviceRGB [ /ICCBased (iccprofiles/sRGB.icc) (r) file ]
>> setinterceptcolorspace
  /Profile (iccprofiles/SWOP.icc) (r) file
>> setreproduction

Without color management, device spaces are converted to the output device using the standard device space conversion from [RB3]. In the case of /DeviceRGB, it would be converted to a CMYK device using under color removal and black generation. This is difficult to configure and never produces good color throughout the whole gamut, but can be arranged to produce plausible color for some of the gamut.
