OverprintICCBased (user param)

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

If the OverprintICCBased user param is set, treat CMYK ICCBased color spaces as DeviceCMYK for the purpose of non-zero overprinting, if the resulting ICC transform results in no color conversion, i.e. if the two profiles in the transform match. This will happen when any of these cases are true:

• setreproduction has no profiles, and the OverrideCMYK setinterceptcolorspace attribute is true.
• setreproduction has profiles, the OverrideCMYK setinterceptcolorspace attribute is true , and the first profile in setreproduction matches the DeviceCMYK profile from setinterceptcolorspace.
• the job is being processed as PDF/X-3+, when a CMYK ICCBased color space matches the OutputIntents profile.

OveprintICCBased has no effect unless the overprint mode graphics state attribute has been set, see OverprintProcess (user param).

Default: false. Automatically set to true for PDF jobs treated as PDF/X-3+.
