As far as I understand it I need to make sure all of the black lineart is k100 while black lineart 4 pixels in from the edge of the lineart is a rich black something like 60C40Y40M100K. I'm only found descriptions of how to do it in photoshop.
The overprint pure black seems like its turning all the black into a rich black but I'm having a hard time understanding how to edit/understand the output of Separate+ as far as getting cymk values and changing them to other values.
