摘要： The present invention suppresses the adverse effect of air currents resulting from ink ejection, regardless of the moving speed of a print head, to allow high-grade images to be printed. Input image data is converted into print data corresponding to each of a plurality of nozzle arrays so that an amount of ink droplets ejected from each of the plurality of nozzle arrays and ejected per unit area is different depending on the moving speed of the print head.

摘要： In an inkjet printing apparatus having a plurality of printing modes with different scanning speeds, first and second preliminary discharge performing positions are provided within the moving area of a carriage as positions where preliminary discharge is performed to cause a printhead to discharge ink irrespective of printing, and a combination of positions where preliminary discharge is performed is set from the first and second preliminary discharge performing positions in accordance with the scanning speed in a set printing mode. This makes it possible to execute preliminary discharge at intervals within necessary intervals even if the scanning speed is decreased when high resolution printing is performed.

摘要： This invention provides a printing apparatus which employs a print head constructed to minimize a memory area to hold ejection data and not requiring a sophisticated manufacturing technology and thus realizes a print mode to perform a higher-than-normal-resolution printing, making it possible to form a high quality image when needed. For each of cyan and magenta that make large contributions to the formation of an image, four nozzle arrays are allocated. For each of the remaining colors, two nozzle arrays are allocated. For cyan and magenta, the interval between adjoining nozzles of the paired two arrays is set to ¼ the nozzle pitch. For cyan and magenta, all of the four nozzle arrays are used in the high resolution print mode and, in the normal print mode, only two of the four nozzle arrays are used for printing. Of the paired adjoining nozzle arrays, only one is used.

摘要： The present invention provides a liquid application device and an inkjet recording apparatus, which are capable of supplying liquid to a liquid room with the power consumption and/or the noise which are reduced. A pump is driven to fill a liquid retention space S with an application liquid. When the filling has been completed, the pump is stopped. Subsequently, the application liquid is applied to an application medium which has been transferred. At this time, a count in a RAM is increased. Thereafter, the determination as to whether or not the application can be carried out is made on the basis of the count and the prescribed application-performable number of sheets stored in a ROM. If it is determined that the application cannot be carried out, the filling of the application liquid is performed. If it is determined that the application can be carried out, next application is performed.

摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： A present invention reduces the generation of periodic uneven print density in the image in a main scanning direction. The present invention focuses attention on a fact that, when a printing head including a plurality of nozzle arrays for ejecting different inks is used to print an image and when the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short, the displacement of ink impact positions is smaller when compared to a case where the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively long. Thus, a dot arrangement pattern allocated to the pixel data is selected so that the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short.
