Abstract: PROBLEM TO BE SOLVED: To restrain tone-jamp pr pseudo-contour from occurring by stopping the discharge of dilution liquid in accordance with the stoppage of ink discharge of a head being in a threshold value or lower at limiting a quantity of the ink discharge of one print head into a given threshold value of lower, and limiting a quantity of the ink discharge of another print head into a lager value than that. SOLUTION: When a quantity of the ink discharge of two print heads is limited into a given threshold value or lower and a larger value than that, stoppage means 22 is furnished for stopping the discharge of dilution liquid in accordance with the stoppage of the ink discharge of one print head. Namely, stopping signals generated in CPU 5 are sent out to the stoppage means 22. Herein, when printing signals limit the ink discharge of two print heads as being a threshold value or lower and a larger value than the threshold value, the transmittance of discharge timing signals to a discharge oscillator driving part 15 of one print head is interrupted to thereby stop the discharge of dilution liquid along with ink.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of photographic printing quality and long time required for printing out from being generated in treatment when an all white data is inputted. SOLUTION: Recording paper 1 is fixed by pressure onto a drum with a paper-fixing by pressure roller 3 provided axially to the drum 2. A feed screw 4 is provided on an outer periphery of the drum 2. A printer head part 5 is held with the feed screw 4. The drum 2 is connected to a motor 9 via a pulley 6, a belt 7, and a pulley 8. The feed screw 4, rotation of the motor 9, and head driving 10 are connected to a driving control part 11, and the driving control part 11 is connected to a control signal generating part 12. Then, when an all white image data is inputted to the control signal generating part 12, a diluting solution is discharged to any printer head by the driving control part 11.

Abstract: PROBLEM TO BE SOLVED: To print even at an accurate print gradation level with uniform quality without reducing the substantial resolution even due to the temperature change of a print head or environmental temperature change. SOLUTION: A CPU 5 corrects image data to be printed based on the temperature detected by a temperature sensor 40, and generates a print data signal from the corrected data. A head application signal for driving a print head 16 is generated from the data signal after the correction.

Abstract: PROBLEM TO BE SOLVED: To enable effective avoidance of lowering of the quality of an image printed on a recording medium, by providing a means to supply an ink jet head part with a head drive signal for controlling a state of jetting of printing ink from each nozzle end part in the ink jet head part, and others. SOLUTION: Data DA1' to DAn' being the respective bases of a set of an ink jet control signal QI1 and a transparent solvent jet control signal QW1 to a set of an ink jet control signal QIn and a transparent solvent jet control signal QWn, which are head drive signals formed in a head drive signal forming part 66, are obtained by subjecting data DL1 to DLn obtained from a frame memory part 62 to a gray level information transform processing executed by a gray level information transform part 65 and also to an area tone computation processing executed by an area tone computation part 64 and enabling output of a multiple value. This enables avoidance of the lowering of a gray level and a tone due to the nonuniformity in the characteristics of jetting of printing ink of nozzle end parts in an ink jet head part, and others.

Abstract: PURPOSE:To rapidly form a mixed soln. with accurate concn. in a mixing part and to contribute to the increase of a printing speed. CONSTITUTION:In an on-demand ink jet printer wherein the ink soln. from a pressure transmission chamber 3 and the ink from an ink quantifying part (electroosmosis membrane device) are mixed in a mixing part 5 to form a mixed soln. and an electrostriction vibrator 4 is intermittently driven corresponding to printing data to intermittently emit the mixed soln. from an orifice 6, when the transmition of ink is not desired, the electroosmosis membrane part 13 of the ink quantifying part 2 is driven by a pulse having polarity inverse to that of the pulse at the transmission of the ink. By this constitution, braking force is generated in the electroosmosis membrane part 13 by the pulse of inverse polarity to prevent the transmission of the ink and, therefore, the ink can be accurately and rapidly quantified.

Abstract: PURPOSE:To carry out the intermediate tone printing having the uniformity of image by a method wherein an ink ejection nozzle ejecting an ink and a transparent solvent ejection nozzle ejecting a transparent solvent are closely located and the ink and the transparent solvent are mixed outside of the nozzles. CONSTITUTION:On the starting of the printing, a pulse type do voltage is applied on opposing mesh electrodes provided on the each surface of an electric permeation membrane 16 of an ink reservoir section 5 to supply a specified amount of ink 4 from an ink supplying passage 7 to an ink ejection nozzle 13 of a mixture nozzle section 8 so that the ink is not ejected from an ink nozzle 15 to stay at an outlet with being a ball shape. Next, a specified voltage is applied on opposing electrodes 11a of an electrostrictive vibrator 11 to reduce a volume of an ink reservoir 3 by the distortion of the electrostrictive vibrator 11 so that a transparent solvent 2 is ejected from a transparent solvent nozzle 14. At that time, the ink ball is influenced by the movement of the transparent solvent 2 and they are unified with each other to form a mixture liquid which is ejected from a mixture nozzle section 8 and spouts. The pressure applied on the ink reservoir 3 is effectively transferred to the mixture nozzle section 8 without hindering a transparent solvent supply passage 6 by means of a one way valve 9 disposed therein.

Abstract: PURPOSE:To significantly shorten the printing time of an ink-jet print head which spouts ink and transparent solvent after mixing them up, by applying water-repellent finish on the inside of a mixing part where the ink and transparent solvent are mixed. CONSTITUTION:While printing is not performed, transparent solvent 4 and ink 9 are repelled by water-repellent finish 14 applied on the inner circumferential face of a nozzle 7 and prevented from entering the nozzle 7 and from being mixed naturally. Then, when a heater 2 is energized to heat them, bubbles are produced inside the transparent solvent 4 and adiabatically inflate, causing the transparent solvent 4 to be pushed into the nozzle 7. At this time, the transparent solvent 4 is mixed with the ink 9 protruding inside the nozzle 7 to make a mixed liquid 13 and protrudes from a spout 12 of an orifice 11. When heating by the heater 2 is stopped, the bubbles are deprived of heat by the transparent solvent 4 surrounding the bubbles and deflate to extinction, however, the mixed liquid 13 is spouted from the orifice 11 at this time. Air enters the nozzle 7 after the mixed liquid is spouted, and the ink 9 and the transparent solvent 4 return to the initial state due to the surface tension of the water-repellent finish 14.
