<snip long explanations>

Thanks to those who responded. I have confirmed that Sumatra PDF and
Multivalent PDF readers render the text correctly. Only Adobe Reader 9
and
Acrobat 8 show the bolded text, and they truly do show the text as
bolded,
it's not zoom-dependent. It happens with both the URW and the CMR fonts;
they're the only ones I tried.

here is an minimal example; I've posted a summary also on comp.text.pdf.

\documentclass{book}
\usepackage{graphicx,lipsum}

\begin{document}
\lipsum[1]
Surrounding text is NORMAL
\includegraphics{singleclickbutton2}
\lipsum[5]
\newpage
\lipsum[1]
Surround text is BOLD
\includegraphics{singleclickbutton3}
\lipsum[5]
\end{document}

The actual files are here:http://www.jtartlabs.com/test/
the pdf is test.pdf
The source files: test.tex, singleclickbutton2.png,
singleclickbutton3.png

please let me know if you have a clue as to what's going on. I haven't
been
able to google a direct answer.

thanks,

Tim,

Bizarre. Both your posted pdf file and the one I get by compiling
your source show up without bold text in my acrobat reader version 8.0
(for linux).

Best,

J.

Thanks for taking a look. I've sent the pdf around and when people view it
at large zoom levels, the effect is not very noticeable. If you look at it
where the page fits in the reader (around 40% zoom on my monitor),

But you said it wasn't dependent on the zoom!
I quote:
Only Adobe Reader 9 and Acrobat 8 show the bolded text,
and they truly do show the text as bolded, it's not zoom-dependent.

I have seen this many times. The text isn't bold, it is
simply darker, as if rendered with a different set of
rules. This is suggested by the fact that the effect IS
zoom dependent.

It seems to me that it started occuring when I got an LCD
monitor, but it could be that simply coincided with moving
up to AcroReader 8.0. I have a 7.x installed elsewhere. If
I have time, I'll look at it there.

I don't think there is any solution. I also don't think it
is related to pdfTeX, but I will see if I can find the
effect in non-TeX documents.

Well, to my eyes, the effect is there no matter what the zoom level is, but
it's not that noticeable at large zoom levels. The thing is, I include the
graphic and I see the effect, include another graphic and I don't see it. I
don't see it on mac's preview, but I do with adobe reader 9.1 and acrobat 8,
on both XP and Mac OSX.

you're right that the text isn't actually bold; it must have something to do
with the smoothing used. I realize my test pages aren't a big deal, but in
my original doc (that unfortunately I can't share) the effect is more
noticeable.

I'll work on getting a better test case. Maybe there is no fix, but for now
at least I'll keep trying. I also don't think this has anything to do with
pdftex; I think it's a bug in the adobe pdf viewer.

thanks,
