The familiar Properties dialog appears:
Font Properties Dialog
You can change font style attributes and the FOND properties here in the
same way as for the TrueType fonts described earlier. And one more option
becomes available when a multiple master font is converted: Create
instance. You may check this option if you want to create a single master
Type 1 font, but you MUST check this option to convert to a TrueType or
OpenType font. That is why, if you change the font type to TrueType or
OpenType PS this option will be checked automatically.
Note: Multiple master fonts have characters with varying parameters
(width, weight etc.) by their nature. If you choose some constant values for
these parameters and fix them you will get an "instance" of the font that is
a plain Type 1 font.
Note: You cannot alter the advanced font options for multiple master fonts
but you can do this for an instance.
