Ghostscript colorconversionstrategy monochrome

Post by jhgrredbjhj I'm trying to convert a bunch of pdf's previously created with Ghostscript to monochrome. They were generated from cad drawings and are vector based.

The lines are red and I want them to be black. I do not want any type of anti-aliasing, halftone, dithering, grayscale or anything like that.

Does anyone know how to do this? Post by Helge Blischke Post by jhgrredbjhj I'm trying to convert a bunch of pdf's previously created with Ghostscript to monochrome.
