# Broken display of 11pt typewriter text in Acrobat Reader [duplicate]

This question already has an answer here:

I set some all-caps words in my document as typewriter. Using scrartcl as documentclass, with a default fontsize of 11pt, yields a PDF that looks rather bad in Acrobat Reader. Here is an example:

\documentclass{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\begin{document}
\texttt{FOO\_BAR}
\end{document}


When using another documentclass like article or with documentclass scrartcl and the option [fontsize=10pt] everything renders fine. I tested Acrobat Reader 11 on MacOS Lion and Version 9 on Windows XP. On the other hand, using e.g. MacOS Preview or Skim as PDF viewers, even the original version with fontsize 11pt renders fine.

[Update] Here is a screenshot of the rendering in Acrobat Reader 11 on MacOS Lion:

and a screenshot from the rendering in MacOS Preview:

Here you can see that e.g. the letters F and R in Acrobat are not as high as the other letters, in contrast to the rendering of Preview (or when using a fontsize of 10pt or 12pt).

[Update] This is not a duplicate of Why are Bitmap-Fonts used automatically?. In my example you can see, that I already use modern and I just checked, that Acrobat really says that Type 1 fonts are used. So I have no problems with bitmap/Type3 fonts.

Is there any way to make those typewriter texts look good in Acrobat Reader with size 11pt?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

• Could you add a screen shot of how it looks bad in AR? – doncherry Mar 16 '13 at 18:19
• Looks fine on my computer, with Adobe Reader XI. – Leo Liu Mar 17 '13 at 7:25
• This isn't a duplicate. But I fail to see how the first screenshot is bad. The TT font has a pixely look but that's just how the font looks. – Christian Mar 17 '13 at 20:08
• This is IMHO a duplicate of [tex.stackexchange.com/questions/98410/… does Latin Modern make strange-appearing output?), which is marked as a duplicate of [tex.stackexchange.com/questions/1390/… Modern vs cm-super?). The issue is in the (in my opinion) not perfect hinting of lmodern font. – yo' Mar 17 '13 at 21:26
• This is indeed a duplicate of Why does Latin Modern make strange-appearing output? (thanks to tohecz for the link). The best workarounds seem to be using another fontsize like 10pt or 12pt or using another font (like the BlueSky Computer Modern variant). – Stefan Nobis Mar 18 '13 at 8:39
