NLQ grid
Because the NLQ characters can use as many as 
18 
dots vertically
and 12 dots horizontally, you plan your designs on a different grid
than the one for draft characters.

Grid 
for 
NLQ characters
On this grid you can use any numbered line or space. As you can
see, that includes the bottom line and the line on the right side. You
should remember to leave one or two columns blank for space
between characters, however.
Each NLQ character definition requires 36 data numbers. There-
fore, each vertical column must be divided into three sections for the
calculation of data numbers. The process is not difficult once you get
some practice using it.
Figure 7-7 shows a single column to make clear how the data num-
bers are calculated. Notice that using circles instead of dots in design-
ing NLQ characters makes it easier to keep track of overlapping dots.
