I would like to export a figure exactly as seen when opened in Matlab. However, in the resulting pdf file the legend text extends beyond the frame and the title partly overlaps with itself. These issues do not occur when exporting to png.

clc;close all;
d=dir('*.fig');
for i = 1:1%length(d)
   fn=d(i).name;
   myfn=openfig(fn)
   %set(myfn,'PaperPositionMode','auto');
   print(myfn,strrep(fn,'fig','pdf'),'-dpdf');
   %saveas(gca, strrep(fn,'fig','pdf'), 'pdf');
   close all
end

Example figure: https://dl.dropboxusercontent.com/u/12598822/4-2-1-geschw-10.fig

Any help would be appreciated, since I already tried several suggestions from the forum, but none worked so far.

I think the issue you're seeing is because the font used in the generated PDF file is not the same as the font specified in the figure.

In the example figure you posted, both the title and the legend are using Calibri as the font. The exported PDF file uses Courier instead.

MATLAB supports a small set of fonts when exporting to PDF and PostScript, and Calibri is not one of the fonts that is supported. If the font isn't supported a substitution occurs when exporting, and in this case Courier is being used.

If you set the axes and legend text to use Helvetica instead you should see better results.

% this assumes   ax    and   leg   are handles to the axes and legend objects: 
set(ax, 'FontName', 'Helvetica');
set(leg, 'FontName, 'Helvetica');

Thanks, that worked

This might be a bit overkill, but it's good enough:

clc;close all;
d=dir('*.fig');
for i = 1:length(d)
   fn=d(i).name;
   myfn=openfig(fn)
   set(myfn,'PaperPositionMode','auto');
   set(gca,'FontName', 'Helvetica')
   axes = findobj(gcf,'type','axes')
   set(findall(axes,'type','text'),'FontName', 'Helvetica')
   set(findall(gcf,'type','text'),'FontName', 'Helvetica')
   set(findall(myfn,'-property','FontName'),'FontName','Helvetica')
   legend = findobj(gcf,'Type','legend')
   set(legend,'FontName', 'Helvetica')
   print(myfn,strrep(fn,'fig','pdf'),'-dpdf','-painters');
   close all
end
