INK ANALYZER AND COMPENSATOR

摘要

In an ink drop writing system a vibrating nozzle forms drops, which are thereafter deflected electrostatically, whereby characters or waveforms are written on paper by the deflected drops. The fluid resonance of the ink must be considered in the design of the nozzle if good drop formation and printing is to be obtained. This invention maintains a desired fluid resonance by compensating for the effects of evaporation on fluid resonance.
