Ink jet heads less susceptible to rectified diffusion and methods for preparing them. |
摘要 |
<p>The present invention provides an ink jet print head having an improved driver design and capable of extended and continuous periods of operation with substantially reduced rectified diffusion-induced printing quality degradation. In preferred ink jet print heads of the present invention, the ink-contacting portion of the surface of the diaphragm of a piezoelectric ceramic/diaphragm drive mechanism is electropolished. By electropolishing only a portion of one surface, the ink-contacting surface, of one ink jet print head component, rectified diffusion is greatly reduced. <IMAGE></p> |
