As I complete the masthead for a book, I see that the publisher has sent me a .png
for the new (to me) "printed on acid free paper" symbol — there's a version of it on Wikipedia,
but after a quick and lazy search I haven't found any discussion about the history or status of the symbol.
I also don't find "acid" in the Unicode character index (accessed 20120919), so I'm guessing this thing hasn't made it into Unicode yet.
Is there a standard LaTeX command to generate it? Or shall I make do with \includegraphics
?
Edit: The forms I've seen look like the Arabic numeral 8 rotated counterclockwise 90° and placed in a circle. I wonder if an infinity sign is not actually what is intended, rather than an eight. But I'm not sure who to ask.
Edit 2: Actually, the publisher has identified it as U+267E, so that gives me another way to enter it. In the several fonts where OS 10.8 finds it present, it is indeed an infinity-sign inside.
Best Answer
The symbol is in Unicode
Wikipedia, Acid-free paper, says:
I have not found the symbol in The Comprehensive LaTeX Symbol List. There is not a "standard" command in LaTeX for this symbol.
Unicode/OpenType/TrueType fonts
These fonts require LuaLaTeX or XeLaTeX.
The glyph is contained in
Deja Vu Sans
:Font
XITS
/xits-regular.otf
:Font
STIXGeneral-Regular
/STIXGeneral.otf
:Solution with
TikZ
Without a font that contains the symbol, it can be constructed with
tikz
, for example:Edit: If you are using LuaLaTeX or XeLaTeX, then the symbol can be used directly as unicode character:
The
TikZ
solution also works with other TeX compilers.I have edited the examples to use document class
standalone
. Thus the examples generate a PDF page with the symbol. The margins are cropped entirely (solution viaTikZ
) or to the bounding box of the characters (solutions with Unicode fonts). The PDF file can directly be included in pdflatex (or xelatex). Or it can be converted to PostScript to support latex/dvips, e.g. viapdftops
ofxpdf

This avoids including a bitmap file (
.png
).
