摘要： An inkjet recording head using pigment ink as discharged ink includes a nozzle member having a nozzle for discharging ink. The nozzle member has an ink-repellent layer forming a discharge port face having a discharge port that is an open end of the nozzle. The ink jet recording head further includes a projection portion positioned around the discharge port and protruding along a central axis of the nozzle with respect to the discharge port face. The nozzle, in a cross section passing through the central axis of the nozzle, has an outline shape provided with a curved line having a changing curvature radius. A point at which the curvature radius of the curved line is minimum is included in the projection portion and has a maximum height from the discharge port face in the cross section.

摘要： A flexible-film wire substrate is bent at first, second and third bent portions. Wires of a flexible wire pattern are deflected at least between the second bent portion and the third bent portion so that a pitch increases from the second bent portion toward the third bent portion. By bending the first, second and third bent portions so that the wires are substantially orthogonal to each bending line, the flexible-film wire substrate can be excellently bent without influencing the flexible wire pattern on the flexible-film wire substrate.

摘要： In an ink-jet printing apparatus in which a carriage mounting an ink-jet printhead having a plurality of nozzles arrayed in a row of even-numbered nozzles and a row of odd-numbered nozzles for performing printing by discharging ink from the print elements is scanned back and forth over a print medium in a direction cross to the direction in which the print elements are arrayed to thereby print on the print medium, print data in conformity with the structure of the printhead is generated from entered information. Printing is carried out upon thinning print data, which is printed by the nozzles of the row of odd-numbered nozzles, if printing is performed by scanning the carriage in the forward direction, and upon thinning print data, which is printed by the nozzles of the row of even-numbered nozzles, if printing is performed by scanning the carriage in the reverse direction. This improves print quality by reducing edge roughness.

摘要： An ink jet head is provided with an orifice plate having a plurality of discharge ports being open thereto. This ink jet head comprises evaporation suppressing groove in the vicinity of the discharge ports. With the arrangement thus formed, it becomes possible to heighten the humidity in the atmosphere in the vicinity of discharge ports, hence suppressing the evaporation from the discharge ports for the prevention of unstable discharges.

摘要： There is provided an ink jet printing apparatus and a printing method capable of reducing unevenness due to a time lag. An ink jet printing apparatus comprise a printing head including a first and a second eject port array. The second eject port array is shorter than said first eject port array in said conveying direction of the printing medium. The first eject port array has a first a second. The first eject port group is disposed parallel to said second eject port array. The second eject port group is not disposed parallel to the second eject port array. In an identical printing area of the printing medium, a printing ratio of the first eject port group is lower than that of the second eject port group. The second ink contains a component that reduces dispersion stability of the first ink.
