Has the software screwup under which Adobe Acrobat 5.0 refuses to print (that
is, distill) any documents containing EPS files exported from Mathematica and
containing Mathematica's default "Math1" fonts been fixed yet?
(I'm not looking for workarounds, which I've already had to implement. I'm
asking if Mathematica has either issued a patch adding the necessary legal
stuff to its fonts, or Adobe has issued a patch relaxing its legalistic
enforcement so that Acrobat 5.0 will now do what all earlier versions of
Acrobat used to do? For those not already familiar with the problem, more
FONTS, LAWYERS, AND PERSONAL COMPUTER SOFTWARE
Something over a year ago I incorporated into a Microsoft PowerPoint
presentation a number of Encapsulated PostScript (EPS) plots prepared using
Wolfram's Mathematica software.
Recently, working against a tight deadline I attempted to print this
presentation to a PDF file as I had done in the past, except this time I was
using the latest upgrade (5.0) of Adobe Acrobat. The result was an Acrobat
error file which said (irrelevant items excised):
Math1 font cannot be embedded due to licensing restrictions. Font vendor (WRI
) does not permit this font to be embedded in PDF. Rest of job will be
ignored; no PDF file produced.
I'm not qualified to sort out the legal tangles here, but it appears that
Wolfram actually does allow its "Math1" font to be embedded in PDF files.
SInce the Math1 font data as embedded in the EPS files does not contain an
explicit release, however, Acrobat 5.0 refuses to print the offending file
(although earlier versions of Acrobat would do so).
There is a well-documented Mathematica command that one can use to switch to
Helvetica (an unrestricted and widely used font) as the default font for
graphics. If you replot and re-export all your graphs using Helvetica as the
default font, and if the axis values are all positive and you use no special
symbols or punctuation in the axis labels, Acrobat 5.0 will create the desired
As a further refinement in the art of user torment, however, if either axis
extends to negative values Mathematica inserts the negative axis labels into
the EPS file using Helvetica for the numerals but Math1 for the "-" signs, and
that's enough for Acrobat to refuse to create a PDF file Similar results
happen if the axis labels contain many common non-alphameric symbols, such as
simple parentheses; Mathematic uses Helvetica for the letters, but outputs
punctuation and other symbols in Math1 instead of Helvetica.Turning off this
(bizarre) default font substitution behavior can only be done using an obscure
and essentially undocumented Mathematica flag.
