IBM Identification
The IBM Identification system uses a different approach from the one used
in the PANOSE system. This system is based on the font’s appearance. In
the IBM system two numbers that designate the font category and sub-
category identify each font. A font’s design is compared to one of the
“standard” and well-known designs.
To set IBM Identification information select a Category that matches
your font from the IBM Class list. Then select a sub-category in the IBM
Subclass list.
A detailed description of the IBM Font Identification system may be found
in the TrueType font format specification on the Microsoft Typography
