@hakan_geijer @abolisyonista Hi! Indeed, we sanitize all PDFs we host on our website for security reasons (and then apply OCR to make the text selectable again), which is where the blurriness comes from. We try to find a compromise between readability and small file size. But you seem to think those PDFs are too blurry, so we'll enhance their quality a bit and upload new versions today or tomorrow. And of course, feel free to download the original files on opsec.riotmedicine.net which do not suffer from this issue.
