[Tex/LaTex] Can’t get the pdf and .ps files to use type 1 fonts

acmdvipsfontspstruetype

I am preparing a paper for submission to ACM proceedings and Digital Library. However, I keep getting the "Your pdf and .ps files both use type 3 fonts, you need use type 1 fonts" error from the publishing house.

I have generated plots in PS and PDF formats and both utilize type 3 fonts. I would love to avoid any solution that would require me to reproduce the plots (using matplotlib and python) as much as possible (The computation time to recalculate would mean that I miss the deadline).

I tried the command:

dvips -P pdf -t letter -o <file>.ps <file>.dvi

as well as 

\usepackage[T1]{fontenc}
\usepackage{lmodern}

and still get type 3 fonts in my PS files and PDFS

I wonder how can I rectify the font type issue. Is there a way to change the font of a PDF or PS plot after-the-fact to produce a compliant PDF and PS version of my paper without any type 3 fonts?

PS: I'd appreciate detailed explanation, as I am new and just getting started with these tools. And I don't mind less than ideal workarounds.

If pkfix and pkfix-helper are not able to help, the easiest way is to use a tool that can take the document with text in embedded fonts and convert them to curves/outlines. That way there is no embedded fonts of any kind that can be of trouble. It also saves the effort of trying to find suitable replacement fonts etc.

Since your .ps files contain DocumentMedia DSC comments let's use them to save some work.

$ grep DocumentMedia class_1_best_describer_mention.ps
%%DocumentMedia: 555x608 555 608 0 () ()

Open the .ps file in almost any major vector-based drawing program. For example in CorelDraw either select Import text as curves when opening .ps file or select Export text as curves when exporting as .eps. In others it may be called Create Outlines or something similar.

Edit the exported .eps file and add the line above starting %%DocumentMedia: somewhere near the line starting %%BoundingBox:.

If you want, you can change the .eps ending to .ps.

To create the .pdf file. From the DocumentMedia line above take the dimensions and put them to command below into the corresponding DEVICE*POINTS options.

$ ps2pdf -dDEVICEWIDTHPOINTS=555 -dDEVICEHEIGHTPOINTS=608 class_1_best_describer_mention-2.ps class_1_best_describer_mention-2.pdf

Now you have files that will pass.

However, the best way is to follow the directions in Avoiding Type 3 fonts in matplotlib plots.

I have converted the example files you provided and have them available if there is still need for them.
