摘要： A continuous-stream ink jet printhead (10) is disclosed utilizing constant thermal pulses to perturb the ink streams (11) emitted through a plurality of nozzles (27) to break up the ink streams into droplets at a fixed distance from the nozzles whereat the drops are individually charged by a charging electrode in accordance with digitized data signals. Each printhead has a manifold, a plurality of ink channels (22) communicating at one end with the manifold and terminating at the other end with nozzles, and at least one resistor addressed by a predetermined frequency of current pulses for applying thermal pulses to the ink. In one embodiment, a resistor is positioned in each of the channels adjacent the nozzles, and in another embodiment, a single resistor is located in the ink manifold. The resistors are pulsed at low power to generate a perturbation of ink properties such as density, viscosity, or surface tension, without producing a phase change in the ink.

摘要： An ink jet printhead is provided with improved filtering of unwanted contaminants which are contained in ink being supplied from an ink manifold (22) into an ink inlet (25) of the printhead (10). A filter (14) is formed in a thin film by a laser ablation process in which output laser radiation is directed through a mask or imaging system creating the desired filter hole pattern. The radiation is controlled so that slightly tapered holes are formed in the film. The holes constitute a filter element which is then laminated to the ink inlet of the printhead. The tapered filter pores or holes provide improved flow/impedance and add increased structural strength to improve handling and processing of the filter.

摘要： A continuous liquid drop generator (25) and a printing system employing it are disclosed. The generator includes a thin cavity (29) which contains liquid under pressure. The liquid is emitted through a nozzle (31) as a liquid column from which drops are formed. The liquid in the cavity is acoustically stimulated by a thin, flexible piezoelectric exciter (27). Polyvinylidene fluoride (PVF 2 ) is one piezoelectric material disclosed. The thin body generator includes a transmission plate or block (28) between a backing plate (26) and a nozzle plate (30). The transmission plate (28) chemically protects the exciter and provides space for an infeed conduit (32) that couples a liquid to the thin cavity. The generator design is especially suited for multiple-nozzle drop generators. One printing system disclosed employs a multiple nozzle generator with each nozzle addressing drops to multiple pixels within a segment of a scan line. Collectively, the drop streams emitted from the multiple nozzles are able to compose a full scan line on a target. The target moves relative to the drop generator.

摘要： A liquid drop generation apparatus for an ink jet printing system uses a thin film of polymeric piezoelectric material, such as polyvinylidene fluoride (43, 55, 69) operated in the piezoelectric thickness mode, to stimulate liquid drop formation. The film is placed against a rigid wall (25, 62) of a liquid-fitted chamber (22, 63) having at least one nozzle (32, 64) for emitting a continuous stream of liquid (41) from which the drops (42) are formed. The rate of drop generation is related to the frequency of an AC voltage applied across the piezoelectric film.

摘要： A color spatial filter (36) for ink jet color printers, especially four color CYMK printers. The printer (22) includes an enhanced print mode, activated by a switch (42) located on the printer (22) and associated logic circuitry which examines and corrects black pixel coloring to increase black picture quality and reduce intercolor bleeding. This is accomplished by examining a surrounding neighborhood of pixels around each pixel as they flow to a color swath print buffer (34) and selecting a method of correcting the representation of each pixel, based on a set of predetermined rules, to produce black by choosing either K, a slow-drying high density ink, or CYM, a fast- drying ink having low intercolor bleeding to thereby control bleeding characteristics that provide the best copy quality images. A lookup table may be used for greater gradations of black representation. Alternatively, printing may be performed using a color printer having two black inks, each with different drying rates and picture qualities. In this case, the filter (36) examines the color space pixel planes (40) and enhances the image by updating the color space pixel planes with CYMK₁K₂ based on each pixel and its associated neighborhood of values.
