first six faces), it seemed unlikely that I would ever have
the opportunity to revisit the fonts.Until 1993, when
Fontographer added the interpolation feature (now called
Font Blend).
Using interpolation, I could quickly create intermediate fonts
between the Bantamweight and Featherweight types; more
importantly, using extrapolation (using a blend amount
greater than 100 percent), I was able to carry the changes
from the wider Featherweight font, through the narrower
Bantamweight font, into a new typeface, a super condensed
sans serif I dubbed Champion Gothic Flyweight.
By caricaturing the ways in which the Bantamweight and
Featherweight fonts differed, the new extrapolated font
highlighted some of the design flaws in the original two
faces, which I was able to easily correct. But most
importantly, this technique enabled me to create a new font
in just MINUTES rather than weeks.
