Optical correction of a font
means that capital letters are
different measured heights even
though they appear the same height.
An O or a W are actually taller by
measuring than an H. An A is
somewhere between the two.
This is to do with the alignment of
characters on the baseline where,
for example the points of a W
actually sit below the line to ensure
that the letterform appears to sit
comfortably. Similarly the curve of
the O sits below the line. The H,
having no curves or points, sits on
the exact baseline.
Incidentally, this is why, when
people use Letraset or other rubdown
lettering systems, they often end up
with wobbly lines—unless they use
the Esselte Letraset alignment system
that takes account of it.
But in font design, there is
also optical correction of stroke
thicknesses. Particularly in S, but
also surprisingly in I, and any straight
strokes, the actual shape of the
stroke is full of nuance. Rarely, even
in the most deceptively geometrically
constructed sans serif font, is there
a straight line, due to optical cor-
rection. Most straights are, in fact,
subtle curves that come in at the
waist of the straight stroke and fan
out at the top and bottom.
The mistake made by many font
redrawers was to trust their eyes!
So you will miss the nuance, but
who cares as long as it looks okay?
And it probably will look okay at text
sizes up to about 12 point. But when
won’t it look okay?
This is where the digital font
revolution has really made an impact.
All those original nuances become
obvious in enlargement. But so do
any of the font redrawers’ short cuts.
If you’ve tried to enlarge a poor font,
you will know the problem—it looks
ugly, ungainly and lumpy. Points are
often not sharp and smooth curves
can have an unsightly kink in them.

Why spend money on original fonts?
Why not use the many lookalike font
clones that are available in cheap
font sets? This is not font piracy
(where you copy a font that someone
else has paid for). This is where a
new font is released and becomes so
popular that other font companies
create lookalike fonts in order to
keep their customers from changing
to a new supplier. But they don’t pay
the original font designer or buy the
original drawings from the original
font producer—they redraw their
own version. It happened with
Helvetica, which is available as
Megaron, Helvetia and Geneva.
It happened with Palatino, which
is available as Palatio, Palladium
and Andover.
It’s happening still, although
there is a new twist in the legal
definition. In a 1998 US case, it was
upheld that although the designer
still can’t copyright the font design
itself, the software program that
defines the font can be copyrighted.
But what’s wrong with it, aside
from dubious ethics and dodgy
principles? Why is it worth the
money to get the original?
Most designers would
acknowledge that the original font
contains nuances that most redraw
copyists appear to have been
unaware of or ignore. This nuance
is most often found in optical
correction. The designer of a font
will often draw a geometrically and
measurement-correct letterform only
to find through tests and close
observation that, when our eyes
see that character, we perceive it
incorrectly. We may thicken one part
of it or see an oval where a circle
is desired.

This is often an indicator that they
were scanned and redrawn from a
printed character that had gained
thickness due to inking in the printing
process. It also means that the
originally finely tuned contrast
between the medium and bold
versions of a face can also be lost.
The other testing that an
original font designer will do is to do
with how particular character pairs
set and the overall texture of the
new font in text setting. This is all to
do with interletter spacing and
character kerning.
The redrawer will not have
spent the same amount of time as
the originator in the detailing of
those combinations and the testing
of the setting, so often uneven
setting results with a redrawn font.
This is okay if you are prepared to do
the kerning and letterspacing
yourself, but how much actually
gets done that should?
Originators of a font will
also spend more time creating the
full font requirements for high-end
publishing—they will often create an
expert set and sometimes foreign
language font sets to match.
