摘要： A printhead includes a jetting module, deflection mechanism, and catcher. The jetting module includes a nozzle array extending along a length of the jetting module and forms drops travelling along a first path from liquid jets emitted from the nozzles. The deflection mechanism causes selected drops to deviate from the first path to a second path. The catcher intercepts drops travelling along one of the paths, includes a drop contact surface and a liquid removal conduit connected in fluid communication by a Coanda surface including a radial surface having an array of grooves. The array of grooves extends in the same direction as that of the nozzle array. For a given groove, the groove includes a depth that varies along the radial surface as viewed relative to the drop contact surface and a liquid removal conduit surface adjacent to the Coanda surface.

The jetting module forms drops travelling along a first path from liquid jets emitted from the nozzles. The deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path to a second path. The catcher, positioned to intercept liquid drops travelling along one of the paths, includes a drop contact surface and a liquid removal conduit connected in fluid communication by a Coanda surface including a radial surface including an array of grooves. The liquid removal conduit includes a surface that is positioned opposite and spaced apart from the radial surface such that the opposite surface of the liquid removal conduit does not contact the radial surface that includes the array of grooves.

摘要： A group timing delay device is provided to shift the timing of drop formation waveforms supplied to drop formation devices of nozzles of one of first and second groups so that print drops formed from nozzles of the first and second groups are not aligned relative to each other along a nozzle array direction. A charging device includes a common charge electrode associated with liquid jets formed from the nozzles of the first and second group and a source of varying electrical potential between the charge electrode and liquid jets. The source of varying electrical potential provides a charging waveform that is independent of print and non-print drop patterns. The charging device is synchronized with the drop formation device and the group timing delay device to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.

摘要： A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

摘要： A device and method of controlling fluid flow are provided. The method includes providing a moving fluid including a fluid flow characteristic; providing a fluid control device including a fluid control surface, the fluid control surface including a pattern; causing the fluid to contact the fluid control surface of the fluid control device; and causing the fluid to interact with the fluid control surface of the fluid control device using the pattern of the fluid control surface that, when activated, causes adjacent fluid drops to merge or coalesce while the fluid is in contact with the pattern of the fluid control device such that the fluid flow characteristic of the fluid after interacting with the fluid control surface of the fluid control device is different from the fluid flow characteristic of the fluid before interaction with the fluid control surface of the fluid control device.

摘要： Preparing a flexographic member (60) includes providing a digital image and calculating a relief image based on the digital image. At least one stress-sensitive boundary region (11) adjacent to at least one image feature is identified and the relief image is created on the flexographic member. The depth (18) of at least a portion of a floor region (10) adjacent the at least one image feature is increased to provide a modified floor region.
