How do I avoid Type3 fonts when submitting to ManuscriptCentral

This is not the precise answer to the original question but it explains how I got LaTeX manuscript submitted to manuscriptcentral when there are complains about Type3 fonts:

Some of the embedded figures were exported eps from matlab. It seemed that matlab is not able to handle font embedding correctly. However, once I imported them into inkscape and converted the svg to eps I was able to have eps figures that were accepted by Rapid Inspector and that also allowed the compilation on manuscriptcentral to proceed.

EDIT: For any of this to work it is obviously crucial to export vector formats from matlab (neither png nor tiff, which are raster image formats, will be of any use in inkscape). A general solution for exporting is described by matlab directly: http://se.mathworks.com/matlabcentral/fileexchange/23629-export-fig . Note that some people find the following customization of that procedure useful: https://stackoverflow.com/questions/14446960/exporting-eps-from-matlab .

I had the same problem. I replaced a \mathbbm{1} command I had with \mathds{1} and the issue has been resolved: no Type 3 Font Error in Manuscript Central.

I encountered the same problem, but I resolve this problem by simply forcing the online submission system using Latex mode = PdfLatex, whose default is XeLatex.
