Droplet jetting

Piezo. This is the same basic print head technology as in continuous inkjet. The ink jet droplets are forced out through the nozzle after an electrical signal to the piezoelectric crystal causes a pressure wave to be set up in the ink (Figure 2.35b). The wave can be produced in the bend mode, as in Figure 2.35b or in a push or shear mode. An important variation on piezo technology is the Xaar... [Pg.144]

Thus, trajectories for the jet droplets result, which may differ. Depending on the elevation of the leak above the ground, the direction of emission, the type of material and the droplet size, the droplets may vaporize before they reach the ground. Droplets which reach the ground form a pool from which further liquid vaporizes in the course of time. Due to these processes droplets are formed which differ in trajectory and extent of vaporization. [Pg.477]

Different doses of the drugs in a single dosage unit could be produced by varying some printing parameters, such as the distance between jetted droplets and the physical dimensions of the printed dosage forms. [Pg.266]

Secondary Disintegration of Jet Droplet When the jet di tegrates, the iuitial droplet size is given by the above correlation. However, often these initial droplets can be relativd y large and may not be stable. The droplets from the jet can further disintegrate under two conditions. These are... [Pg.153]

Recent work performed by Dong et al. describes the visualization of DoD ink-jet droplets in order to address the FDP in more detail. The combination of a pulsed laser, a low-speed charge coupled device camera, and signal generators enables an imaging system based on flash photography that is able to... [Pg.152]
