摘要： Reproducing a predetermined pattern on a medium, by for example, an apparatus that includes in combination a source of colored ink, a primary source of compressed air, a spray head including a housing having an inner ink chamber in flow communication with the source of ink, an outer air chamber in flow communication with the source of air and surrounding the inner ink chamber, a spray nozzle having an outside diameter and an internal longitudinal bore connected to the inner ink chamber and extending forward of the housing. A spray shield has an outer surface adjacent the medium and an inner surface positioned adjacent to and spaced from the housing and has a transverse opening therethrough in alignment with the nozzle. An auxiliary air supply has a pressure significantly less than the pressure of the air from the primary source of compressed air. The auxiliary air supply is in flow communication with the space between the shield and the housing thereby to force clean air through the space and out through the spray shield opening.

摘要： A system for printing images on a substrate includes a multiplicity of print heads mounted in a carriage and positioned a distance from the substrate. A sensor detects the thickness of the substrate as the substrate moves through the system, and a control system receives the substrate thickness information detected by the sensor and transmits signals to a motor coupled to the carriage. These signals instruct the motor to adjust the position of the carriage to maintain a desired gap between the print heads and the substrate.

摘要： A system for copying images onto a long sheet of paper or vinyl while. A flow of constant-pressure air is pulse-width modulated in accordance with the control signals and passed over an ink meniscus maintained on the end of a small nozzle. The pulse-modulated air flowing across the meniscus causes the ink to be sprayed onto the recording medium. The dot size on the image remains constant and the pulse width within each pixel is varied to produce the desired density of color. Pressure surges in the ink supply system, produced for example by vibration or acceleration of the ink, are suppressed by a second meniscus in the ink-supply system, formed by a gas bubble or interface near the nozzle meniscus. The second meniscus should have a surface area at least as large as that of the jet meniscus. At the end of each pixel, the ink flow is interrupted for a period of about 100 microseconds to restore system equilibrium. A second and continuous air flow around the air nozzle supplies air to the turbulent flow across the ink jet and reduces recirculation of atomized ink and minimizes contamination of the nozzle and adjacent surfaces. The supply roll is mounted at each end on independently movable arms.

摘要： A printing apparatus for printing images on a substrate includes a first set of print heads S1 having at least one print head P1,1 arranged to deposit a first ink I1, and a second set of print heads S2 having at least two print heads P2,1, P2,2 arranged to deposit a second ink I2. The at least one print head P1,1 of the first set S1 and a first print head P2,1 of the second set S2 respectively depositing the first ink I1 and the second ink I2 in a first order of deposition O1, and the at least one print head P1,1 of the first set I1 and a second print head P2,2 of the second set S2 respectively depositing the first ink I1 and the second ink I2 in a second order of deposition O2 as the printing apparatus traverses across the substrate in one direction D1. The order of deposition of the first ink I1 and the second ink I2 from the print heads is reversed as the printing apparatus traverses across the substrate in an opposite direction D2.

摘要： The invention is embodied in a pressurized ink supply system for a three color ink jet printer. In order to provide a relatively large ink supply, three stationary primary ink reservoirs, formed as three long tubular sacks of flexible plastic film, contained in a pressurized disposable cartridge, are connected through flexible plastic umbilical tubes, and three solenoid-operated valves, to three secondary ink reservoirs mounted on the movable carriage of the print head. Automatic ink replenishment and an out-of-ink alarm are controlled entirely from the secondary ink reservoirs.The ink level in each secondary reservoir is maintained within close limits without attention from the operator. When the primary reservoir runs out of ink, as indicated by failure of the secondary reservoir to fill within a specified time period, an alarm alerts the operator to remove and replace the ink cartridge. The pressure in the primary reservoirs forces the ink to the secondary reservoirs under automatic control, and under manual control for purging the ink passages by momentarily opening all of the solenoid valves.Each secondary reservoir is provided with a rigid tub-like bottom covered by a thin flexible dome. An optical sensor is provided in each secondary reservoir that detects the level of ink in the reservoir. This sensor activates one of the solenoid valves to allow ink to flow into the appropriate secondary reservoir. If the secondary reservoir has not been filled within the normal fill time, a signal alerts the operator that the primary ink reservoir is empty and the ink cartridge should be replaced.
