None of those commas should be present, and they significantly change the meaning of the sentence. With them (especially the first), it means that all Monotype fonts have been specially adapted to these recommendations and carry The Name Affix, which is “1450”. The commas serve equivalently to parentheses: “Monotype fonts (which have been specially adapted to these recommendations) carry the name affix ("1450").”
What they meant was: “Monotype fonts which have been specially adapted to these recommendations carry the name affix "1450".” That is: the subset of Monotype fonts so adapted are identified by the presence of the “1450” name affix.
A remark like this would normally be off-topic on HN, but I mention it because (a) the line threw me, for a couple of readings, and I only resolved it because I know Monotype fonts have been round much longer than this DIN 1450 thing and by inference from the next sentence; and (b) correct language usage is at least as important as font when it comes to “barrier-free reading”.
Some of the other commas in the article are also wrong in the same and similar ways. I’m curious whether there might be something about comma usage or sentence structure in the native language of the author, which I’m guessing isn’t English. (There are a few other mildly unusual or clumsy word choices and sentence structures, and a few minor errors. Given the context, probably German.)
