How to set the black text to "overpriint"?

Discussion created by coastgis on Apr 6, 2012
I???m trying to print a map on a commercial press from ArcGIS. I believe a PDF file is the best way, so I exported a CMYK PDF, 600 dpi, and sent it to the printer.

They report that the black text on the map causes a ???knock-out??? in the other colors that the black text has to fit into, instead of ???overprint???ing the text. This is very difficult to register on even a good press.

Is there any way to instruct ArcMap to ???overprint??? the black text instead?

Does one do this in the software setup or in the PDF export?

Thanks for any hints,
