Because the NLQ characters can use as many as 16 dots ver-
tically and 11 dots horizontally, you plan your designs on a dif-
ferent grid than the one you used for draft characters. Make up
some grids (photocopy Figure 6-12 if you wish) and get ready to
be creative!

II Figure 6-12. Use this grid (or one similar to it) to define your own
NLQ characters.
As you noticed when the NLQ characters are printed, they are
printing in twice; the first line of data is printed, the paper is
moved up a distance of l/2 dot, then the second data line is
printed. So, we’ve written the numbers on the horizontal lines.
To calculate the data numbers for this column, you see which
dots are used in the box and add their values together. Then you
go down the dots on the horizontal lines and add their values
together as shown in Figure 6-13.
Now we’ll show you how to use the NLQ character definition
with a flask as shown in Figure 6-13. Figure 6-13 shows the
design drawn on a grid and the data numbers printed at the
bottom of each column.
If you look at each column individually, you can see how the
data numbers were calculated.
