Any commercial printer should be able to accept a PostScript file. I would
recommend setting the publication up as CMYK, Greyscale (black and white) or
Spot colour first (depending on what you need), then print (or save to) a
PostScript file, however be sure that you print the file as CMYK not
publisher's default of RGB. I have had the best results using the Creo
Colour printer driver (set to print to file) to create PostScript files, but
any generic level 2 PostScript driver should work well. I have had a lot of
problems with the Acrobat Distiller driver, especially on large or complex
Publisher files, the use of Wizards and drag and drop graphics/tables/charts
seems to make the situation worse.
Regardless of which PostScript print driver used, sometimes I have found it
necessary to print a few pages at a time (for multiple PostScript files) to
get the files to work, unfortunately you can't tell if you have a problem
with the PostScript file until you distil the file (turn it into a PDF).
Although I have found the Acrobat Distiller is the worst for this always look
for objects layered in the wrong order, missing objects, etcetera in the PDF
file. The only solution I have found is to print fewer pages at a time for
that Publication.
Be aware Publisher sometimes does not let you know that there has been a
problem creating the PostScript file,it churns away for a long time, then
acts like it has finished printing but no PostScript file is produced, this
indicates a PostScript error has occurred. The only solution I have found is
to print fewer pages at a time for that Publication.
