Figure 8-5. 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 be-
tween 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 8-6 shows a single column to make clear how the data
numbers are calculated. Notice that in designing NLQ characters we
suggest using circles instead of dots to make it easier to keep track of
overlapping dots.
