Normally, Document Fonts created in packaging are for the file they are sent with.
However, I believe if you copied your variation InDesign files into the same folder, they should work as well. I think InDesign always opens Document Fonts found in the same folder as the InDesign file itself.
Make a book file, add all these files and package the book, so you have no double files.
Thanks for replying Steve. A man who worked at a press, told me that InDesign files always pulled fonts from the same folder first. My coworker thinks it's only the InDesign file that fonts were packaged for. Now I don't know for sure what he meant and I don't have a way to contact him again.
More experimentation on my part will be required and more packaging of files. Our Creative dept has 3 designers and when we work on each others files, there's always font issues unless the fonts have been packaged for each file. And don't get me started on Helveticas! Between system fonts, fonts used over the years, clients providing fonts... it's been a problem we've yet to solve... everyone using the same Helvetica font family.
Again, thanks Steve.
Thanks Willi. I'll have to look into making book files. I'm not familiar with the process or procedure. But I'm going to learn about it.
