All the fonts are embedded, so not a font substitution issue.

Could you be specific on what needs improvement instead of just "looks terribly ugly"? Comments like that are not helpful. I can only guess what the problems you're having are. I can't reproduce your rendering issue on my machine. If your font had been successfully loaded by Freetype then "Both" would not overlap like it does. We will start shipping with Freetype on Linux starting Chrome 60. We have also recently fixed the overlapping issue. To improve the rendering right now, you'll need to update FreeType version in your machine so that the embedded font is successfully loaded. Re #3: I don't think this should reproduce on Mac and Win, can you confirm you reproduced issue on those? Closing for now, will reopen if there's anything that should be addressed.

Kerning is awful. Glyphs are antialiased from above and below which is totally unnecessary. It really is dirty and ugly, while Adobe Reader's rendering is neat and tidy. |
