摘要： PROBLEM TO BE SOLVED: To adjust and compensate an ink ejecting frequency of a recording head when interstices of ink droplets become uneven caused by an uneven pattern induced on a recording medium. SOLUTION: An ink ejecting frequency is controlled in order to compensate unevenness of a recording medium in printing by controlling ink ejection based on adjusted frequency of a recording head. A control can be performed individually or by the same controlling signal by using a plurality of recording heads corresponding to a different color ink. The control can be changed even in bidirectional printing based on printing direction. An adjustment of ink ejecting frequency makes it possible to provide a predetermined uneven pattern having a periodic wave-shaped portion on the recording medium, determine the number of ink droplets ejected within each area by dividing each periodic wave-shaped portion into a predetermined number of areas, determine a space between gate alleys of each area, provide at least one parameter according to printing operation and decide a difference of an ink ejecting trigger.

摘要： PROBLEM TO BE SOLVED: To enhance wiping efficiency by wiping an ink jet recording head having a wiper cleaner twice continuously during a wiping sequence. SOLUTION: A recording head is moved in a first direction, for example, while passing over a lowered wiper and then it is moved in the first direction to the ascending position of wiper which is then elevated (S805). Subsequently, the recording head is moved in a second direction opposite to the first direction and elevated to be wiped off by means of the wiper (S807). The recording head is then moved in a second direction to a wiper descending position and the wiper is lowered (S810). Thereafter, the recording head 15 is moved in the first direction over the lowered wiper to the ascending position of wiper before the wiper is elevated (S814). Thereafter, the recording head is moved in the second direction and the ascended wiper is wiped off by means of a wiper cleaner (S816). Finally, the recording head is moved in the second direction to the descending position of wiper which is then lowered (S818).

摘要： PROBLEM TO BE SOLVED: To perform gas-liquid exchange between the ink in an ink containing section and the atmosphere well by introducing the atmosphere forcibly into a communication passage at the time of ink supply using an atmosphere introduction passage by disposing a negative pressure generating member in a passage coupling an atmosphere communicating section with the upper end of the atmosphere introduction passage. SOLUTION: When an ink jet recorder is operated, an ink suction force is generated in an ink tank 1. Consequently, an ink 9 is sucked from an ink containing section 6 and passed through a gap 8, between the end B of rib and the bottom 11 of ink cartridge, for communicating the ink containing section 6 with a negative pressure generating member containing section 4 to the negative pressure generating member containing section 4 thence sucked through a negative pressure generating member 3 into a joint member 7 and fed to an ink jet recording head. Since the negative pressure generating member containing section 4 is opened through an atmosphere communication port 13 to the atmosphere, the air passes through the negative pressure generating member 3 and enters the ink containing section 6 through the gap 8 between the rib end B and the ink cartridge bottom 11. Consequently, the ink in the ink containing section is exchanged with the atmosphere quickly in safety at the time of supplying ink.

摘要： PROBLEM TO BE SOLVED: To prevent the drop in whole saturation and to obtain an image having high quality while the reproducibility of an achromatic color is maintained by adding an achromatic signal generated based on an extracted achromatic component to plural color component signals which are color- corrected by a color correction means. SOLUTION: In a 'luminance-density conversion processing' step, original image data (Rin, Gin and Bin) are inputted from a computer 7, a luminance- density conversion processing is executed on RGB image data and they are converted into CMY image data (Cin, Min and Yin). The achromatic component K1 is extracted from CMY image data and chromatic components C1, M1 and Y1 are generated. Then, the chromatic components C1, M1 and Y1 are color-corrected and chromatic components C2, M2 and Y2 are generated. Then, C, M, Y and K are density-corrected and CMYK image data C3, M3, Y3 and K2 are obtained. Then, a black generation processing is executed. An output correction processing is executed on data and CMYK image data are obtained. Then, they are sent to a printer and a color image is formed on recording paper.

摘要： PURPOSE: To increase a density of black images by discharging and overlapping an ink including a component that makes a coloring material insoluble or coagulate at points where a black ink is discharged. CONSTITUTION: When an ink jet unit 103 scans forward, in a printing area of a black image, a black ink is discharged from each discharge port 30n of a head 30K, then a cyan ink is discharged from a head 30C to pixels indicated by K+C. As a result of this, the black ink and cyan ink come into contact with each other and react, whereby dyestuffs are turned insoluble or coagulated. Thereafter, a yellow ink is discharged from each discharge port 30n of a head 30Y to pixels indicated by K+Y. The yellow ink is discharged upon necessities so as to adjust a color tone of the black image. If it is necessary to adjust the color tone, a magenta ink is also discharged. In this manner, a density of the black image is increased and a boundary part between the black image and a color image is prevented from blurring.

摘要： PURPOSE:To prevent lowering of the drying-prevention property and to enhance the reliability in a standing condition by a constitution wherein a part of or all of a rib of a cap of a capping device that is in contact with a face of an ink jet record head is made multiplied. CONSTITUTION:A cap 20 comprises doubled ribs 21 that have a function like a sucker. The ribs 21 are deformed by being pressed against a face by an elastic force so that a part of an air between ribs 21 is discharged therefrom. When the cap is pulled by a force of vibration or the like, a gap between the ribs has a negative pressure so that it acts as a resistance force against the pulling. In the case where an outer pressure against the cap 20 becomes zero when the pressing force of the cap 20 is removed by the vibration, the pressure from the outside always acts on the cap 20 caused by the negative pressure between the ribs, thereby obtaining a resistance force that is greater than that of a conventional cap against the shift in the traverse direction. Even when the cap 20 is shifted in the traverse direction, a leakage of the air is prevented by means of the inner rib.
