Wow - 5 hours and no reply.
Seriously - the bloatware that is Adobe software (because we really need it updated for 'features' constantly just like micro$bloat) SHOULD have this feature.
They should even be able to sell it for crissakes.
Chriscozi - have you ever worked for a vendor ISV/OEM ? My guess is probably not. Typeface ownership / patents / copywrites on fonts ( or better said, somehow wrangling them within a software application or RIP/DFE is a losing proposition. Before we could embed the fount within that PDF/X file ( THAT YOU CUSTOMER SHOULD BE DOING NOW SINCE THEY CAN ) - we needed to have the DFOs ( Definitive Font Outline ) loaded into the RIP - in the case of KANJI type fonts, the wee MASSIVE ( so, when AFGA would sell a RIP in Japan or China, it was VERY expensive and came on multiple large hard drives )
We do not have this issue when you don't need 10,000 glyphs in your fonts character set.
It is 100% solve is the designer save the file to be exchanged as a PDF/X file.
if they are too ignorant to build a proper PDF/X file - or - there is some complex flexo type ( complex trapping / distortion / spot color overprinting ) workflow where you require they send the original Adobe Illustrator file - then - as it relates to fonts - they need to INCLUDE them when they send the file ( totally legal to do that as long as you only use these fonts with THAT customer.
So, totally solvable 100% of the time.
