[Tex/LaTex] Type 3 fonts in output PDF file

fontspdf

I am trying to submit an article through ScholarOne Manuscript Central. However, when I try to look at the PDF proof I get the Font Type 3 error.

I have used PDFLatex to compile the file, using eps images generated directly from Matlab, and some PDF figures generated from Visio.

From other posts, I have seen that it is advisable to export the images from Matlab to InkScape first. Is this necessary?

Besides, I have seen that you can use pdffonts to find all font types in the document and done so. From that file, I have the following fonts:
Type 1, True Type, and CID True Type. Which ones are the Type 3 fonts?

Do you reckon I should just play with the Visio files or should I export the Matlab figures to InkScape first?

Thank you in advance for the help!

EDIT: here is the error message I get from Manuscript Central when I try to visualize the PDF proof:

I received a Type 3 Font error during PDF creation. What should I do?
A Type 3 font error is due to bit mapped fonts in your document or missing fonts used within the document. Bitmapped fonts display poorly on screen in PDF files and sometimes cause printing problems. We recommend for Word Documents that you embed your fonts and re-upload the file(s), or for PDF's save them using Acrobat 6 (or lower).
If your fonts are all uploaded to the manuscript or embedded, please also check the file name. If you have uploaded a TeX file and there are spaces in the file name, it will not convert. Remove the spaces in the file name and re-upload the file and the Type 3 Font error message should no longer display when you try to view the PDF.

Best Answer

The full error message you quote says that it is "bitmap or missing fonts", not just typ3 3 fonts that cause the warning.

The only font not embedded in the list you show is helvetica, presumably that has come from some external image tool, try to get it to embed fonts.
