Prepress whose responsibility?

I was always interested in this question : prepress layout, it is the responsibility of the designer or the responsible employee in a particular printing will print the layout ?

Free printing will not do it. That is, padding, layout, color separation to CMYK, overprint and trapping, output to PDF / etc to do the designer. However, the same descent of the pages (if printed book) they will do on their own.
