摘要： A liquid dispenser includes a liquid supply channel, a liquid dispensing channel including an outlet opening, and a liquid return channel. A liquid supply provides liquid under pressure from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A selectively actuatable diverter member imparts heat energy directly to a first portion of the liquid to divert a second portion of the liquid toward outlet opening of the liquid dispensing channel.

摘要： A continuous inkjet system includes a plurality of nozzles producing a respective liquid jet through each nozzle. A stimulation device at each nozzle is responsive to different types of stimulation signals to produce a modulation in the respective liquid jet to selectively control droplet break off relative to phases of the cycle of a varying voltage source that is connected to a charge electrode. The break off phase of a droplet relative to the voltage phase of the voltage source will determine whether the droplet is charged or not charged. Droplets that become charged may be deflected from their paths and a deflection mechanism including the charge electrode determines which droplets are allowed to reach a surface for say printing and which droplets are collected and not deposited upon the surface.

摘要： A liquid dispenser includes a liquid supply channel, a liquid supply adapted to feed a stream of liquid through the supply channel, a liquid return channel adapted to receive liquid from the supply channel, a liquid dispensing outlet opening, and a diverter member selectively movable into the supply channel to divert droplets to the dispensing outlet opening. The liquid flows from the liquid supply channel to the liquid return channel by Coanda effect when not diverted. The motion of the diverter member is substantially orthogonal to and opposes the direction of liquid flow, so that energy associated with moving the diverter member imparts no energy to the diverted droplets. The energy associated with moving the diverter member is less than 100 nJ per pL droplet volume. In some embodiments, the energy associated with moving the diverter member is less than 10 nJ per pL droplet volume.

摘要： The present invention provides a method for reproducing image data from a press output on another device. The present invention mimics color, resolution and frequency of dots used by varying the color saturation (amplitude) of the dots used to mimic the defining characteristics of the source output. By allowing adjustments in both frequency and amplitude to vary from the original output device, it becomes possible to match the resolution and color of the source device.
