I am on an iMAC with Sierra 10.12.5
MY PROBLEM: One of the fonts in my 3.6 MB PDF Document hosted on Box.net seems to have changed or become corrupted.
I do not use Sync.
My hosted document displayed perfectly for many months, but one of the fonts looks TERRIBLE.
My original font had a serif. The font displayed now does not have a serif and the letter-spacing is a mess!
I thought all fonts in a PDF are "frozen," --like part of an image?--Can anyone tell me why a font has changed?
If you would like to have a look, here is the LINK:
