The "Bold" button would use a real Bold if it was available. Sounds
like the typeface used doesn't have a true bold and a synthetic is
being generated. The way to check is to highlight some of the "Bold"
text and then open the Character Designer to see what it says about
the font. If the Weight attribute says "Bolded" then it means that FM
has to fake it.

Either an incomplete set of fonts was used or the typeface simply
doesn't have a Bold. This might be a more serious issue, since you may
have to change to a different typeface to get a true bold.

Otherwise, you can use the Change & Find options to substitute a real
Bold for the fake Bolded. First, create a Character tag that has the
font that you want in Bold (set all attributes to AsIs except for the
Weight, which you would set to Bold). Apply this bold characters tag
to some text and then do Edit > Copy Special > Character Formats to
load the tag into FM's clipboard. Now, using Find & Change, set the
Find option to search for Character Formats > Bolded and set the
Change to "By Pasting". You can change all of the Boldeds to true Bold
this way.
