Transtype 3 never did a good job creating font families, I was hoping version 4 would do better. I'm using the latest Mac download version of Transtype 4. I am importing .otf fonts and exporting PS .otf. I assemble the font and export and the resulting family works correctly in Word for Mac. Word for Windows does not see the bold members of the family and fakes a boldface. I've tested in Word 2000, 2003 and 2007. I also tried exporting as .ttf, same problem. I'll be glad to send samples. You're going to have to do better if you want my money.
