Whew, a great help Peter - thanks!

I was beginning to think that maybe I'd 'backed the wrong horse' in
choosing Scribus, and that I'd have to start again with a commercial DTP
program, with several weeks work wasted!

The pages look OK without bleed and crop marks, so maybe they'll be OK
for the printer. I think what I'll do is copy a test pair of pages to a
USB drive and take it to the printer for checking.

You state: "The PDF contains bleed and trim boxes that the
printers imposition software adheres to, and crop marks are added for
the final spreads."

I don't see these marks. Are they invisible to a viewer, then?

Thanks again for the help.
