Parser error: "Failed to map colorant" appears when trying to RIP a Normalized PDF.
Possible causes and solutions
The Normalized PDF came from DeskPack, where the Ink Manager showed that the Dot Shape was set to 0. Changing this to none allowed ripping without errors.
For a job with external references (e.g. a PDFPLA file), ink were changed in one of the external references without re-saving the master file. Re-saving the master file (PDFPLA) does solve the problem.
