[scribus] PDF Colour separations

[Frank Cox]

To this point, I have been creating plates by printing to a colour-separated ps
file, then doing an imposition from that into four pdf files (one for each
colour) then printing each pdf file to the appropriate series of plates.
Unfortunately, ghostscript blows up once in a while using that output due to, I
think, poor quality fonts being used in the original document.
(10,000 Fonts for $1.49!)  Unfortunately, I can't persuade the folks who create
this thing to stick to using good quality fonts (I've tried several times) so
I'm stuck with the consequences.

I am now considering the idea of starting from a pdf file instead of a ps file
(not knowing if the output will be any different or better or not) but have
discovered that there is no obvious way to create a colour separated pdf file
in Scribus.  Export to PDF has several options, none of which appear to do what
I can do by printing to a ps file.

So my question is, how can I get a set of colour separated pdf files out of a
Scribus-generated PDF file?  I see that ghostscript now supports a tiffsep
device, but that will give me a series of tiffs.  Should I go with that and use
tiff2pdf to create my pdf files for the plates?  Or is there a better way?

Or am I wasting my effort here and won't gain anything different by starting my
imposition and colour separation from a PDF instead of a ps file?
