摘要： A printing apparatus and printing method for improving printing speed in multi-pass printing without increasing the capacity of a printer power source while utilizing a conventional printhead. A plurality of printing elements of the printhead is divided into a plurality of blocks; different blocks are selected from the plurality of blocks for each scan of the multi-pass printing; printing elements included in the selected block are time-divisionally driven; and moving speed of the carriage is increased in accordance with the number of times of scans in multi-pass printing. In multi-pass printing, for instance, in a case where the number of blocks selected for each scan of multi-pass printing is one half of the total number of blocks, the moving speed of the carriage is doubled, thereby achieving high-quality image printing while maintaining high speed of the printing.

摘要： To reduce the number of simultaneously driven printing elements so that the instantaneously flowing current is restricted in a printing system for completing an image by repeating the printing scan a plurality of times in the same printing area while applying random mask thereto. For this purpose, a mask of a predetermined size is structured as a thinning pattern in which data are arranged randomly, the data being for determining whether or not the respective ink ejection openings in a printing head are to be driven when the printing head repeats the scan a plurality of times in the same printing area of a printing medium. When forming an image, the printing elements concerned with the printing operation in the same printing area are divided into a plurality of sections, and the thinning patterns complementary to each other are applied to the respective sections during the respective printing scans.

摘要： A jet, and a method thereof, use bubbles as virtual valves to eject droplets of different sizes. The jet is in fluid communication with a reservoir and has a substrate, an orifice layer, first nozzles, and second nozzles. The substrate has a manifold for receiving ink from the reservoir. The orifice layer is positioned on the top of the substrate to form first chambers and second chambers. First orifices of the first nozzles and second orifices of the second nozzles are formed on the orifice layer. The jet has at least one of following characteristics: (a) the first chambers are larger than the second chambers; (b) an interval between two heating units of the first nozzle is larger than an interval between two heating units of the second nozzle; and (c) the apertures of the first orifices are larger than the apertures of the second orifices.

摘要： A compact monochrome ink jet printhead having a staggered high-density arrangement of ink drop generators for high-performance printing. The present invention provides a high-performance design that enable high-resolution and high-speed printing while reducing cost due to an efficient use of printhead space. In particular, the compact, high-performance printhead of the present invention includes several thermally-efficient aspects that allow a large number of ink drop generators to be placed on a compact printhead while minimizing problems such as thermal excursions. In a preferred embodiment, the ink drop generator density on the compact printhead exceeds 10 ink drop generators per square millimeter and the compact printhead contains at least 350 nozzles. The ink drop generators are arranged in at least four parallel rows. Each row is staggered (or offset) relative to an adjacent row to provide a greater effective pitch that a non-staggered arrangement. The ink drop generators of the present invention include high resistance resistors and a thin passivation to increase thermally efficiency. Further thermal control is achieved by ejecting low-weight ink drops from the thermally-efficient ink drop generators at a high ejection frequency that exceeds 12 kHz.

摘要： A method for operating a printer having vertically offset printheads each having an array of nozzles. A method step includes printing in a first mode which enables a larger number or all of the nozzles of the printheads. Another step includes printing in a second mode which enables only nozzles defining a common print region for the printheads. In one example, the first and second modes occur in different raster lines of the same sheet of print medium. In another example, the first and second modes occur in different print jobs.

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： In an ink jet head, in order to make the occupying area of a chamber associated to each nozzle as small as possible, while maintaining a discharge ink drop volume, and on the other hand, to locate a number of nozzles with a high density, the plan view shape of a pressure plate provided to each chamber is so configured to fulfill the relation of 1:≦A≦2, where “A” is the ratio of an circumscribed circle diameter of the plan view shape of the pressure plate to an inscribed circle diameter of the plan view shape of the pressure plate. For example, the pressure plate is formed to have the plan view shape of a substantial square or a substantial rhombus. The chambers having such a feature are located in the form of a matrix. Thus, a stably driven, highly reliable ink jet head can be realized.
