Using N-Color ICC Profiles

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

In the same way as for CMM custom color spaces, it is also possible to use N-color ICC profiles regardless of the color space used to paint objects. This is a similar configuration to the previous CMM custom color space example:

CODE

<<
  /DeviceRGB [ /ICCBased (iccprofiles/sRGB.icc) (r) file ]
>> setinterceptcolorspace
<<
  /Profile (iccprofiles/SWOP.icc) (r) file
  /NextDevice <<
    /InputColorSpace [ /ICCBased (iccprofiles/CMYKOG-CMYK.icc) (r) file ]
  >>
>> setreproduction

where the CMYKOG-CMYK.icc profile is a device link that also converts CMYKOG to CMYK.

The behavior of the RIP in directly passing named colorants to a /NextDevice is equivalent for both ICC profiles and CMM custom color spaces. However, CMM custom color spaces are often more convenient because ICC profiles can get very large with more than four input components.

The N-color ICC profile does not need to be a device link. It could be an input profile that converts to the ICC PCS as in this corresponding example:

CODE

<<
  /DeviceRGB [ /ICCBased (iccprofiles/sRGB.icc) (r) file ]
>> setinterceptcolorspace
<<
  /Profile (iccprofiles/SWOP.icc) (r) file
  /NextDevice <<
    /InputColorSpace [ /ICCBased (iccprofiles/CMYKOG.icc) (r) file ]
    /Profile (iccprofiles/Flexo.icc) (r) file
  >>
>> setreproduction
