    摘要: A printing control method of a multi-nozzle binary continuous ink jet printer wherein drops of a first category and drops of a second category are formed by jet breaking. The flowpaths followed by the drops of the first and second categories are differentiated. For printing a black pixel followed by a white pixel, a drop of the first category and a drop of the second category are formed. The cumulative formation time drops of the first and second categories is equal to or higher than the running time of one pixel.

    摘要: A method of selecting inkjet nozzle banks for assembly into an inkjet printhead. The printhead when assembled includes at least two nozzle banks and is operative for printing one particular color ink or other liquid and each nozzle bank includes plural nozzles. The printhead is operational in a printer to print raster rows so that at least one raster row is printed using ink drops deposited at respective different pixel locations on the raster row by respective different nozzles on each of the at least two nozzle banks. The method includes (a) characterizing a drop size parameter for predetermined nozzles of each of the nozzle banks; (b) identifying for each of plural raster rows the respective different nozzles on each of the at least two nozzle banks that would be used to print the respective raster row; (c) identifying a size characteristic associated with each of the plural raster rows using a predetermined computer algorithm without printing the raster rows; and (d) determining in accordance with a criterion and data derived from size characteristic identified in step (c) whether or not the at least two nozzle banks are an acceptable match.

    摘要: Apparatus for controlling ink in a continuous ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish a continuous flow of ink in a stream, the nozzle bore defining a nozzle bore perimeter; and a heater which causes the stream to break up into a plurality of droplets at a position spaced from the nozzle bore. The heater having a selectively-actuated section associated with only a portion of the nozzle bore perimeter, whereby actuation of the heater section produces an asymmetric application of heat to the stream to control the direction of the stream between a print direction and a non-print direction.

    摘要: Disclosed is an ink droplet expelling apparatus for expelling an ink droplet in response to an electric signal, compising a printing head provided with one or more ink chambers, electro-mechanical transducers disposed on the printing head corresponding to the ink chambers, and a driving signal generating circuit for producing electric signals for driving the electro-mechanical transducers. The elector-mechanical transducers are distorted by three different driving signals to reduce the volumes of the ink chambers to raise the pressure therein to thereby expel an ink droplet out of a nozzle formed at the front end of the head. The three driving signals are applied to the electro-mechanical transducers in a predetermined order, the first one giving the ink a velocity, the second one accelerating the ink to expel it in the form of an ink droplet out of the nozzle, the third one acting to suppress the pressure fluctuation in the ink chambers caused by the first and second driving signals as well as to supplement ink in the ink chambers from an ink tank.

    摘要: A drop-on-demand printing method comprising performing the following steps in a printing head: discharging a first primary drop of a first liquid from a first nozzle outlet to move along a first path (pA) with a first speed; discharging a second primary drop of a second liquid from a second nozzle outlet to move along a second path (pB) with a second speed, lower than the first speed, wherein the second path (pB) is inclined with respect to the first path (pB) along an axis inclined at an angle (α) from 3 to 60 degrees and crosses the first path (pA) at a connection point; controlling the flight of the first primary drop and the second primary drop to combine the first primary drop with the second primary drop into a combined drop at the connection point so that a chemical reaction is initiated between the first liquid of the first primary drop and the second liquid of the second primary drop; applying electric charge to the combined drop; wherein the path of flight (pC) of the combined drop is altered no more than 20 degrees from the axis of the path of flight (pA) of the first primary drop; and controlling the path of flight (pC) of the combined drop with applied electric charge by deflecting electrodes.
