The vast majority of droplets have a low (or no) negative charge and do not exit the Printhead
Orifice. Instead, they go straight into an Ink Return Gutter, where they are pulled back through
the Umbilical Tube to the Mixing Tank to be recirculated and reused.
The high number of droplets passing through the Printhead each second means that the
JetStream can print at incredibly high speeds: a single-line 5x5 dot image can be printed at up
to 1,000 feet per minute. The solvent-based inks generally used with the JetStream result in
drying times of about a second, all of which makes the JetStream an ideal choice for fast
production lines.
