Preview was once a great PDF viewer. Since the last two or three OSX versions, it became less great, and I wonder what has happened. This is a part of a PDF with editable fields (the numbers can be edited), when I fill them in with Preview: Note how the baseline between the filled-in text and the preexisting text is off. This is what is rendered by Adobe Reader DC: Okay, so Adobe highlights the editable fields blue, let's ignore that. It also seems to have problems with the character heights in the captions, let's ignore that too (this is not a thread for making fun of Adobe). The important thing is that it places the numbers where they are supposed to be, which is vertically centered in the field and on roughly the same baseline as the captions. Now for the interesting thing: I save this PDF with Adobe Reader and then reopen it in Preview: Suddenly, the numbers are correctly placed! But as soon as I edit a number in Preview, it is misplaced again. I am interested in why this happens, and also in whether I can craft the PDF document in a way that is a workaround for Preview's baseline problem. Can someone shed some light on this?
