Transparency depends very much on the output driver and its settings. I
have used it successfully with xdvipdfm, by way of the "opacity" optin in
TikZ; but the resulting output files are version 1.5 PDFs which not every
printer supports. If you're using some other driver (for instance,
anything that goes to Postscript instead of PDF), or if your printer
doesn't like transparency, there may be problems. It is possible to use
Ghostscript to resolve the transparency (convert to a non-transparent PDF
or Postscript file that still looks at it should) but it appears to
accomplish that by rasterizing the file, which may not be suitable for
your purposes.
Thank you for your prompt response, Mathew. In fact, I am using the default
driver (I am not aware how I might alter this), and was simply relying on it
to "do the right thing". If you could tell me how to identify the
driver, and
what possible additional options I might pass to it to improve matters,
I would
be most grateful. As you correctly anticipate, rasterising the output would
be self-defeating : the whole object of this exercise is to generate a
PDF that
contains embedded scaleable fonts and glyphs.
