For about 12 years now, Windows (PCs) and Apple (Macs) have ended support for Type 1 and True type fonts in favor of Open Type fonts. This doesn’t mean that you can’t still buy a True Type font or that they won’t ever work, but it does mean that you are walking on thin ice. Systems and software are no longer developed with these old fonts in mind, with the exception of Adobe who allows you to put the font in the library of the software using it. Even then, you may still encounter problems. So why switch to Open Type fonts? Why should you give up thousands of dollars worth (if you are an agency) of licenses for fonts?
