Thank you for the clarifications and corrections of my
misunderstandings, Martin.
My other thought would be to try printing just the blacK separation
from Opro (or OPW) for distilling to a PDF, but I don't know whether
the black would still be in RGB space or the colour jpegs would be
included and then the print shop could separate the resulting PDF.
Probably adding to confusion again ;-)
