Graham, the best way to print maps from Therion's PDFs is to render them to pictures. I do it in Photoshop. It could be really huge file. Don't render to too high resolution. For A1 150-180 dpi in final size should be enough. RGB/CMYK problem should be solved if one sets the color space of PDF as sRGB in printers software.

I am having one of our surveys printed professionally as an A1 poster and a couple of issues have arisen that it is worth users being aware of. One is that the printer's software had a problem faithfully reproduced some fill areas, mostly stal flow. They solved it but it is worth keeping an eye out for this as some small areas might easily be missed.
The second is the lack of control over colour - not the usual problem of being able to control which colours it uses if asked to colour the whole survey - which I believe is being looked at - but the seeming fact that the output will be coloured RGB when printers require CMYK. I know that Acrobat Distiller can deal with this and generate appropriate files, but I cannot see a way of doing this in Therion.
