[pdftex] Font (embedding) problem

[Marcel Korpel]

Hi,

When using different encoding schemes on the same font, the font name
gets duplicated several times. I haven't experienced any problems with
that, but lately I had to use an Océ printer at my university and
things went wrong.

For instance, when using old-style figures in the body text and lining
figures for footnote numbers, all 1's were printed as a lining figure,
whether they were old-style, lining or superscript ones.

I searched through the archives (and the rest of the internet, of
course) and found a thread at
http://tug.org/mailman/htdig/pdftex/2005-November/thread.html#6191
named "multiple embedded pdf figures", the OP seems to suffer from the
same problem. In this thread someone proposes to process the pdf file
with Ghostscript.

So I did a 'gswin32 -dNOPAUSE -dBATCH -sDEVICE=pdfwrite
-sOutputFile=out.pdf in.pdf' and tried to print the file again.
Remarkably, the problem was gone. Moreover, the file has shrunk to
almost half its original size. pdfTeX version was 1.10a, Ghostscript
version was AFPL 8.51 (as I was at the university, I was not able to
use the newest version; it's in any case rather uncommon to see a TeX
installation at a humanities department).

My questions are:

1. As suggested in mentioned thread, will a newer version of pdfTeX
solve this problem? I looked through the changelog, but couldn't find
something referring to this (at home I use version 1.30 of TeTeX,
which suffers from the same problem).

2. What are the differences between those pdf files output by pdfTeX
and the one after processing the pdfTeX output through Ghostscript?
What causes such a large decrease of file size?

Thank you in advance.

Kind regards,
Marcel Korpel
