I created a series of fonts for a new type designer a year ago. I also created a Bold version for her basic set as opposed to the larger Pro version. She was learning Fontlab Studio along the way and so I declined to do the Bold version of the large font just because of time restraints. So a few days ago I was sent the new Bold version of the larger Pro font and asked about doing fixes. I agreed and did quite a few. What I'm finding now is that I can't seem to get the bold to work as a family with the Regular version. I've read through and tried every version I could with naming schemes and preference settings.
So… my question is: are there any other issues outside of naming that can prevent a weight of a font from becoming a family with another? I should preface that with the fact that I'm not entirely sure of how the original data was pulled into the new Bold version because I know they did copy some bold letters from the Basic Bold that I generated. I ended up having to import kerning data back into the Bold as a result.
