PDF editing is a desperate last resort and if these are company documents you should always find and edit the original but if that is absolutely impossible ( eg deleted, and backups eaten by termites) I have an idea...are you able to select the text then change it to that font (the same name but that would be the one in your computer - or to some other font and back again?
Thanks for your input. Sorry, but I don't follow the suggestion. When I try to edit any text in the document, I am unable to select the "Officina Sans ITC Book" option. It appears at the bottom of the drop down list of fonts, but is grey and "frozen out" - and can not be selected.
I'm looking at it again and it seems like the issue is that I have installed "OfficinaSansITCStd Book" installed, whereas the font I needed is "Officina Sans ITC Book".
I guess they must be different fonts! Very annoying. Will look into it.
Often fonts change over time and the old ones are unobtainable. That's why I suggested CHANGING the font to the new one. It's likely to be very similar.
I am having the same problem. How do I change the font to the new one?
