摘要： A group timing delay device shifts the timing of drop formation waveforms supplied to drop formation devices of one of first and second nozzle groups so that print drops from the nozzle 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 from the nozzle groups and a source of varying electrical potential between the charge electrode and liquid jets which provides a charging waveform that is independent of a print and non-print drop pattern. The charging device is synchronized with the drop formation devices and the group timing delay device to produce a print drop charge state on print drops of a drop pair, a first non-print drop charge state on non-print drops of the drop pair, and a second non-print drop charge state on third drops.

摘要： A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface.

摘要： A laser-ablatable element for direct laser engraving has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. This relief-forming layer includes a laser-ablatable polymeric binder and an infrared radiation absorbing compound that is present at a concentration profile such that its concentration is greater near the bottom surface than the image-forming surface. This arrangement of the infrared radiation absorbing compound provides improved ablation efficiency, particularly when laser exposure is carried out adiabatically.

摘要： A compressed fluid microvalve for controlling flow of compressed fluid from a region of high pressure to a region of low pressure is provided. A chamber includes an inlet port, a region of high pressure, and an outlet port leading to a region of low pressure. A cantilever beam includes a first portion, a second portion, and a third portion. The cantilever beam is anchored to a portion of the chamber and is suspended in the chamber such that the first portion and third portion of the cantilever beam are exposed to the region of high pressure on all sides. The second portion of the cantilever beam overlaps the outlet port. The cantilever beam includes a first position in contact with the outlet port to prevent fluid flow from the chamber through the outlet port and a second position removed from contact with the outlet port to permit fluid flow from the chamber through the outlet port. A controller is in electrical communication with the cantilever beam and is configured to provide an actuation pulse to the cantilever beam to move the cantilever beam from the first position in contact with the outlet port to the second position removed from contact with the outlet port.
