[Therion] PDF generation

[Bruce]

I have (in my small experience) not yet found a large format printer/driver
that can reproduce therion generated fill areas reliably.  Almost always get
recessive hazey dotty rectangular areas, and the transparency settings are
ignored.

I have tried converting to jpg and png but usually going up to 150 dpi
crashes or locks things up, and when 150 dpi does work, while the file looks
OK on screen, the quality of the printed output is so bad as to be unusable,
so I go back to using the original pdf.

I'm working with approx 5MB pdf files that print about 600-1000mm x 2000mm,
and sometimes up to 10MB.

Regards
Bruce

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.

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.
