摘要： An ink jet (10) apparatus and method provides high-resolution gray scale printing by providing multiple PZT drive waveforms (100, 110, 120), each having a spectral energy distribution that excites a different modal resonance of ink in an ink jet print head orifice (14). By selecting the particular drive waveform that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required. Jetting reliability and contaminant susceptibility are, thereby, improved by eliminating the need for an unconventionally small orifice. Changing a selected PZT drive waveform amplitude changes drop ejection velocity without changing drop volume. This invention, therefore, provides for selection of ejected ink drop volumes having substantially the same ejection velocity over a wide range of ejection repetition rates.

摘要： 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.

摘要： A viscoelastic and ink-immiscible fluid is used to form a membrane over the ink orifice of a drop-on-demand, pressure pulse ink jet head. The membrane lies in a plane perpendicular to the direction of emission of ink drops, and provides a barrier between the ink orifice and the external atmosphere. Evaporation of the ink, or entry of contaminants including air into the ink, is thus inhibited. The elimination of evaporative clogging then permits the use of a smaller orifice. Wetting of the exterior surface of the ink jet head by the flow of ink through the ink orifice is also inhibited, thus making possible the production of more uniform ink drops that will emerge in a constant direction. The elastic property of the membrane permits the passage of an ink drop therethrough, followed by the closing up of the membrane. The viscous property of the membrane permits it to absorb any energy of a pressure pulse that is not consumed in ejecting an ink drop, thus inhibiting the occurrence of pressure oscillations that could cause either variations in the speed of ejected ink drops or the appearance of satellite ink droplets.

摘要： An air assisted drop-on-demand ink jet head 10 has an ink chamber with an ink drop-forming orifice outlet 23 from which ink drops are generated in response to pressure waves caused by a piezoelectric crystal 56. The ink drops are carried by air outwardly through an external orifice 24 and toward printing medium. The internal orifice outlet 23 is centered in a projecting structure 48 which extends toward the external orifice 24. In one form, the projection 48 is of a frustoconical or mesa-like shape. Air flowing past the top of the projection prevents ink from wetting anything but the top of the projection, resulting in highly uniform ink drop formation with a single uniform dot being produced on the printing medium in response to each pressure wave.

摘要： Gray scale ink jet printing method and apparatus produce a high quality image having varying color intensities. This is achieved by mixing a colored phase change ink with varying amounts of a clear phase change ink base, thereby producing multiple gray scale levels of each color. The mixing either can be performed prior to placement of the phase change ink in the printer, or can be performed within the printer to produce different levels of color intensity during the printing process.

摘要： Ink jet printing on a liquid medium can be performed using a membrane underlayer. A drop of a liquid can spread on the surface of the liquid medium, forming a substrate for the ink jet printing. The liquid ink can include a thermogelling component which can gelled, e.g., forming gel droplets, when contacting the membrane.
