You know, I did ponder on whether PDF/X-3 was appropriate for non-colour
output. However, from the very informative page here:
I understood that PDF/X-3 is a subset of PDF, specifically aimed at
ensuring the most accurate transfer of printing information. So I
figured it was the most likely format to work, regardless of whether the
content was colour or monochrome. In fact, I recall that there is
mention in the Scribus documentation of old PDF/X-1 supporting greyscale
I have no particular attachment to PDF/X-3, so long as the printer can
easily and correctly print what I send.

Thanks - I didn't think converting to greyscale would be difficult, but
I'm inferring from what you say here that there are better and worse
ways of doing it? :o)

...interesting - thanks for the insight... :o)

Ok, that sounds very helpful. May I ask why greyscale export to PDF/X-3
is not supported? (I'm curious, particularly if it's a case of "we don't
believe it would be really useful to anyone.")

This is the hint that there are better and worses ways of creating
greyscale pics - yes? If I go the scribus script route, I believe I
could call Gimp from within the script to do the greyscale conversion.
If I go the non-script route, then I could convert to greyscale
relatively easily if I can get the data into the RGB colour space.

It's not actually a matter of trusting 1.3.3, it's a matter of
practicality. I removed Scribus 1.3.x from my own machine some time ago,
when I realised that the file formats and font handling were quite
different, and I really had to choose which version I was going to use
for production work. It was sad in a way, because I really liked a lot
of the 1.3 look and feel.
The newsletter in question is going to be produced in the future by
someone other than myself, on a different machine (Fedora Core 4 on an
old G4 PPC), so it is important that we standardise on software.
However, I will certainly test the greyscale PDF export of 1.3.3 as it
may well be the best answer for me, and I will happily provide feedback
to the developers, if that is of any help.
Most helpful indeed. Again, many thanks.
