I am actually producing PDF/X-4 print-ready stuff with Inkscape, ghostscript and Scribus. I even have TrimBoxes and proper CMYK.
But it involves many manual steps, especially overprinting for the K color channel does not work and I need to adjust every polygon and vectorized text manually.
I whish it would be possible all in one tool. I can afford the time, because it is only a hobby. If it would be professional the extra steps involved make it not good enough.
ghostcript can add a color profile, too. I use the regular ISO coated v2 (without the 300%). This is just a step to not do all things in Scribus by hand and make sure colors are not out of gamut.
I don’t now the command line from the top of my head. Just ping me again, so when I am on my computer I can send the complete ghostscript cli line that currently works for me.
The final profile is set up by Scribus, where I have set it to the ISO coated with 300%. Ideally I would like to have less steps in the chain, so that a change in the Inkscape-source involves less manually steps. One can dream of it. (:
I don’t now which of ProcessColorModel or ColorConversionStrategy is the important one. I kept both and did not bother to try to omit one of them. -dPDFSETTINGS=/prepress makes sure that embedded bitmaps are in 300dpi and I think -f prevents Ghostscript staying in interactive mode after all pages have been finished.
If we all spent that money on gimp, scribus and inkscape, they would be so much better in just 2 years.

I use Ghostscript for postprocessing the PDF files. What do yo I use to add a color profile for example?

Here I am again.
I’ve been fantasizing of making a simple GS GUI.
Finally I found the time to write down, how I use Ghostscript:
gs \ -sDEVICE=pdfwrite \ -o /output/gs_file.pdf \ -dPDFSETTINGS=/prepress \ -sProcessColorModel=DeviceCMYK \ -sDefaultCMYKProfile=/path/to/ISOcoated_v2_eci.icc \ -sColorConversionStrategy=CMYK \ source/file.pdf \ -fI don’t now which of
