Graphics
In the figure on the previous page, you can see the main rules for
graphics design in the three densities:
l
In single-density, no dots can be placed on vertical lines.
l
In double-density, dots can be placed on vertical lines, and they
can overlap.
l
In high-speed
double-density,
dots can be placed on vertical
lines, but no dots can overlap.
After choosing the desired density, you design your
fiie
by
plotting dots on graph paper.
The high-speed double-density design shown below should point
you in
the right direction for your own work.
After plotting the
<dots
on a
g&l,
you calculate
thenumbers
for
each pin
pattern
by dividing the design grid into separate print
lines. For the arrow design, the grid was divided into two lines,
each seven dots high. Then each column was examined to calculate
the graphics data. The results for the first line are shown in the
figure on the next page. The pin values are on the left and the sums
at the bottom of each column.
