“I am interested in reclassifying some fonts, so that (a) they show up under one family in a piece of software and (b) don’t conflict with each other thus preventing a font manager like Suitcase Fusion from activating several weights at once.”

Sorry no one’s taken this on. Please be specific: OSx?, what app?, what fonts?

Cheers!

This is a technical question. I’ll move it to the BUILD area.

You should be aware that some foundries would consider this modifying the font. Those same foundries do now allow for it. Your best bet might be to contact the foundry from whom you licensed the type and ask if they can supply you with split families. I know Linotype offers this for one.

This happens on Windows XP and (currently) on my laptop running OS X v10.4 ... I’m having particular problems with a broken family of Scala used by any major application: specifically Illustrator, Photoshop and InDesign CS3. Is that specific enough?

“Is that specific enough?”
Yes. Thank you for your response. My advice is to contact the vendor from whom you purchased the broken family of Scala and have them replace it with a product that works for you.

Cheers!
