摘要： An adverse effect of air flows occurring near the nozzle line with high print duty is reliably avoided by appropriately dividing and allocating the print data to a plurality of ink ejection nozzle lines. When the print head is scanning in a forward direction, a combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used. When the print head is scanning in a backward direction, another combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used.

摘要： A color ink jet printing apparatus is provided which can print high quality color images and black letters without increasing a running cost and a printing time while using nozzle arrays with poor first ejection stability. For this purpose, inks with good first ejection stability are printed overlappingly at those of pixel positions printed by another nozzle array where the first ejection stability problem is likely to be caused by the latter nozzle array ejecting an ink with poor first ejection stability. This makes the first ejection stability problem less conspicuous on a printed image while taking full advantage of desirable characteristics of the inks used.

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 compact liquid ejection recording head capable of forming high-quality images at high speed includes large nozzles for ejecting large droplets, medium nozzles for ejecting medium droplets, and small nozzles for ejecting small droplets. The large nozzles are arranged on one side of an ink supply port, while the small nozzles and the medium nozzles are arranged on the other side of the ink supply port. The number of the small nozzles is larger than that of the medium nozzles, and that of the large nozzles. This allows high-quality and high-speed printing using the small nozzles, high-speed photo printing using the medium and small nozzles, and high-speed printing using the large nozzles.

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 liquid fixing device used for an ink jet recording apparatus for discharging ink liquid onto a recording medium arranged on a given feeding path for the formation of images on the medium includes a housing, a first aperture for inducing air into the housing, a second aperture having a width wider than that of the recording medium arranged on the feeding path, this second aperture being arranged to face the recording surface of the recording medium arranged on the feeding path with given gaps formed between them on the upstream and downstream sides in the feeding direction thereof, a heat emitting source facing the recording surface of the recording medium through the second aperture side portions arranged around the heat emitting source, with the first aperture being arranged on one end and the second aperture on the other end thereof, and exhaust means for inducing the air outside the housing into the housing through the first aperture to guide the air to the recording surface of the recording medium by way of the heat emitting source and second aperture, and to exhaust the air outside the housing by forming the air flow through the aforesaid gaps toward the upstream and downstream sides in the feeding direction of the recording medium. Hence the prints on the recording medium are fixed rapidly at lower running costs.

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.
