摘要： The present apparatus includes: a liquid ejecting head having a nozzle plate with an ejecting hole through which a liquid is discharged, a conductive member disposed behind an object being processed opposite to the liquid ejecting head, a potential difference generating device for generating a potential difference between the nozzle plate and the conductive member, and a switching control device for turning on and off the potential difference generating device. The switching control device decides whether a process to which the object is subjected is a borderless recording process that drops liquid drops on an edge part of the object or a bordered recording process that does not drop any liquid drops on the edge part, and turns off the potential difference generating device when the bordered recording process is executed.

The method and apparatus use insulating ink prepared by dispersing colorant particles capable of being charged in a solvent as the ink composition, allow an electrostatic force to act on the ink composition to form a thread of the ink composition and provide a stimulus to the thread at a frequency in a range of 100 kHz to 800 kHz to separate the thread into the ink droplets. The apparatus includes an inkjet head for ejecting the ink droplets, an electrode substrate for applying a charging voltage to the recording medium and a stimulus providing unit for providing the stimulus.

摘要： There is disclosed an image forming method for mixing a plurality of recording liquids to produce a mixed liquid with a desired density and/or color and transporting the mixed liquid to an image receiving medium to form an image. The actual value of the mixture proportion of the mixed liquid is constantly monitored in the vicinity of the confluent point of the recording liquids (in the vicinity of the downstream side of the confluent point or on the upstream side), and is compared with the target value of the mixture proportion obtained based on the image signal. And the supply amount of each recording liquid is subjected to feedback control in such a manner that the detected actual value agrees with the target value. The mixture proportion is prevented from fluctuating by influences of a recording liquid temperature, an atmospheric pressure, and the like and an image quality is enhanced.

摘要： The invention relates to a method of printing a two-dimensional bit-mapped image having a number of pixels per row, the printhead having a row of ejection channels and each ejection channel having associated ejection electrodes to which voltages are applied in use. During printing, in order to cause volumes of fluid to be ejected from selected ejection channels of the printhead for printing, voltage pulses having values of predetermined amplitude and duration as determined by respective image pixel bit values generated by a raster image processor are applied, at a given pulse period, to the electrodes of the selected ejection channels. The part of the raster image corresponding to an ejection channel is scanned to determine the number of adjacent non-printing pixel periods prior to a pixel to be printed and, immediately prior to the printing of said pixel, a voltage pulse, having a value predetermined in accordance with the time, measured in units of the given pixel period, between the last pixel to be printed and said pixel to be printed, is applied to the ejection electrode.
