I have seen that several authors of scientific papers include in their work, black and white graphics (university logos mainly) that appear to have an incredibly high resolution. I have found the Universidad Nacional Autónoma de México and my university logo with that quality, but recently my university logo has experienced some changes so the one I have no longer works.
I was able to remove the colors of my university logo with a software called Pinta, but the output wasn´t perfect (I got very thin lines) and not a very good quality.
That file is in PDF.
I have read that a way to acomplish this is to create a "font" with just a ligature of the logo, or convert a PNG file to a Vector and save it as PDF. I tried this last option with inkscape, but it looks blurry due to some gray lines produced when I trace my image.
So my question is, How can I acomplish to get a PDF file with the logo of my college in high quality? (I don't know much about graphic design software or theory)
This is my college Logo.
