The figure below illustrates how the pattern editor works. The print origin shifts if a leader
bar gets used. If no leader bar is used the print origin is at the very top left of the pattern.
The figure also shows that the leader gets only printed in those passes of the print head
where the image has content. The leader bar might therefore have gaps in y direction.

Drop Spacing
The drop spacing is the center to center distance in X and Y of the drops that the DMP
deposits to create the pattern. Drop spacing is adjustable between 5 and 254
μ
m in one
micron increments. It toggles with the arrows on the box in five
μ
m increments. For
example, with a 50
μ
m drop spacing, the pattern generator places drops 50
μ
m apart in X
and 50
μ
m apart in Y to fill in your pattern. So, for a 100
μ
m wide, 10 mm tall vertical
line, the system places 3 drops in the X direction (one for the first edge, another at 50
μ
m,
and another at 100
μ
m for the next edge) by 2,001 drops tall. The drop spacing therefore
determines your resolution or density in the X direction and determines the angle at which
the cartridge must be set to get the same resolution or density in the Y direction. The drop
spacing parameter is most useful for altering the fill density (amount of jetted ink per area)
of lines and rectangles, or it may be used to create rows of individual drops which are
spaced closer together than 254
μ
m.
