摘要: Ink-jet printing incorporates a family of different technologies with common end result to form and direct small fluid droplets specific location high accuracy. These fit into two broad classes. In continuous-mode ink-jet technology, jet liquid is formed by forcing under pressure through an orifice. Surface tension forces create instabilities in the cylindrical jet, causing break up drops [1, 2]. By providing controlled single-frequency disturbance, can be forced uniform diameter velocity droplets. The charged during their breakup deflected from straight trajectory electrostatic field. Charging levels allows placed at one several locations on substrate, or directed catcher gutter for recycling disposal [3]. Figure 22.1 shows schematic system, 22.2 photomicrograph array 70 μm jets water issuing droplet generator device breaking ~140 40 kHz.
